Antrees auto tune realtime live Earlier this year, Antares and Universal Audio raised the bar for Auto-Tune on UA interfaces with Auto-Tune Realtime Advanced.With enhanced features such as Classic Mode for the popular “Auto-Tune 5” sound, Realtime Advanced quickly became a favorite for songwriters, producers and mixers. Now it’s time to stir things up again with new Auto-Tune Realtime Access for UA. A UA exclusive, the Antares Auto-Tune Realtime Advanced plug-in improves the previous UAD version with powerful workflow and sonic enhancements, making it the ultimate ultra-low-latency tuning solution for Apollo and Arrow interfaces — optimized for insta. Auto-Tune Artist (formerly Auto-Tune Live) is designed to meet the demanding needs of working musicians, producers, and live sound engineers. It includes all of the advanced real-time pitch correction features of Auto-Tune Pro, and is optimized.

REAPER supports MIDI and virtual instruments. This makes it very easy for you to start creating music using your favorite virtual instrument or edit existing MIDI projects. This tutorial is written for a complete beginner in MIDI music production. At the end of this tutorial, you should learn the following: a.) Understanding the basics of. Jul 12, 2019  VST Plugins Don't Save Settings. 6 months ago 12 July 2019. UnknownReverence 0 replies So I'm using reaplugs by Reaper and I have to redo the settings every time I load SLOBS. I think I saw a post about a month back about it being a problem and being worked on. We're still checking this file's contents to make sure it's safe to download. Want to use some of the comprehensive FX plug-ins that REAPER provides, but stuck in another host? Haven't made the switch yet? Fear not - you can download ReaPlugs, a package of FX that includes many of the plug-ins that come with REAPER, for free! Want to use some of the comprehensive FX plug-ins that REAPER provides, but stuck in another host? Haven't made the switch yet? Fear not - you can download ReaPlugs, a package of FX that includes many of the plug-ins that come with REAPER, for free! Then reinstall reaper, then the plugins (paying close attention to where in the file system these are installed, and confirming that reaper's VST path is pointing to the correct directories). Then reinstate the backups of your work to the default directories that reaper uses to save your projects.

  • Why free?
  • When the plugin was released the first time it was not free. After several years of successful sales, we ran into a set of personal circumstances, that made it impossible for us to support the software as fully as it deserved. Because of that, we made the difficult decision to release it for free.
    Now that we are back and dedicated to the plugin full time again, we have decided to keep it free. Every donation we receive, no matter how small, keeps this project alive and may help us to provide some updates and upgrades in the future.
  • I am completely new to recording and I don't have a host/DAW yet to run the plugin on (only for beginners).
  • Word definition:
    DAW = Digital Audio Workstation = Audio editing/recording software
    If you are new to recording and haven't chosen one of the many DAWs yet, we recommend to try out Reaper, which can be downloaded here:
    Download Reaper
    Reaper has an unlimited 'Evaluation Mode', which means you can (technically) use it for free with all features, even without purchasing a license. This makes it the perfect DAW for beginners.
    As soon as you installed Reaper, you can watch the following video showing the installation and usage of the plugin inside Reaper.

  • How do I install on Windows?
  • Look at the Preferences Menu of your recording software / DAW and find out where your VST folder is located on your system, if you don't already know.
    Open the downloaded zip file and copy both of these files:
    MT-PowerDrumKit.dll
    and
    MT-PowerDrumKit-Content.pdk
    into your VST plugins folder.
    Restart your recording software. You may need to RE-SCAN your plugins folder from inside your recording software.
    If the plugin doesn't show up in your DAW, click HERE, then scroll down and follow the yellow arrow.
  • How do I install on a Mac?

  • 1) Download and unzip the file.
    2) Right-click on the .mpkg file and select open.
    3) Follow the instructions.
    4) Restart your Mac.
    If the plugin doesn't show up in your DAW, click HERE, then scroll down and follow the yellow arrow.
  • How do I install on Linux?
  • Currently there is no native Linux version available. But on the DOWNLOAD page we have a version for Linux, which is actually a Windows version, which was slightly modified to be able to run on Linux with the help of a bridge.
    Important:
    You will need Wine and additionally a bridge like LinVST, Airwave or Carla.
    Please visit THIS WEBSITE to see a detailed general instruction about how to use Windows VST Plugins on Linux in Reaper, Tracktion, Ardour and other DAWs.
    For this plugin it is important to copy both the .dll and .pdk files from the downloaded zip file into the VST folder of your DAW.

  • What is the drum map for and how do I use it?

  • The drum map (some DAWs also call it note names or pitch names) is a separate file, which comes together with a drum instrument and can be imported into the DAW. It will allow the DAW to display the actual drum names (Kick, Snare, etc.) in the MIDI editor instead of just the blank piano roll keys. This makes drum programming much more convenient. Check the following instructions to see what it looks like and how to import the drum map into your DAW:
    Not all DAWs support drum maps. The following are the only ones we know of.
    See instructions for..

  • Using Cakewalk at least one mixer fader jumps down once I hit play.
  • This is a behaviour apparently caused by MIDI files which are exported either from Guitar Pro or Tux Guitar. These programs seem to add weird automation data to the MIDI file which affects drum plugins in the DAW Cakewalk. Not only MTPDK is affected by this.
    A quick solution was provided by Cakewalk once we reached out to them. Watch the following video to see how it works:

  • I am using Studio One and the plugin doesn't show up.
  • At first you need to check whether you have the Pro or Artist version of Studio One.
    Unfortunately, the Artist version of Studio One doesn't support 3rd party plugins, unless you install the following add-on from Presonus:
    VST and AU Support Add-on for Studio One Artist
    If you are new to recording in general and not already very used to Studio One and also not willing to buy the add-on mentioned above, we recommend to try out the audio software Reaper, which can be downloaded here.
    Reaper has an unlimited 'Evalution Mode', which means you can use it for free with all features, even without purchasing a license. This makes it the perfect DAW for beginners.
    As soon as you installed Reaper, you can click here to see a video showing the installation and usage of the plugin inside Reaper.
  • The plugin doesn't show up in my DAW (Mac or Windows).

  • Mac:

    Note: On a Mac the plugin runs only on Intel processors. All Macs of the past 10 years were equipped with an Intel processor. You can check your device by clicking on the top left Apple icon and select 'About this Mac'.
    Some users reported that restarting the Mac after installing the plugin helped the DAW to scan and recognize the plugin.

    Windows:

    Some DAW software simply don't support VST instruments. They support VST effects, but not instruments. Examples of such unsupported DAWs are:
    - Adobe Audition
    - Audacity
    If you are completely new to audio recording and haven't chosen a DAW yet which supports VST instruments, click HERE and follow the yellow arrow.
    For those who already have a DAW which supports VST instruments:
    Make sure to copy both plugin files into the VST folder which is set in the preferences of your DAW. Also, click the 'Re-scan' button if your DAW offers you that. This will re-scan all plugin folders and help to recognize new installed plugins.
    A common mistake is to download and install the wrong 'bit' version of the plugin. As you will notice, there is 32 bit and 64 bit available. Depending on the combination of your operating system and your DAW, you have to select the correct one, otherwise the plugin won't show up.
    Note: A 32 bit software can also run on a 64 bit Windows version, therefore having a 64 bit operating system doesn't necessarily mean that your DAW is also installed as 64 bit. Some older DAWs, like Cubase 5 for instance, were almost only available in 32 bit, but do run on a 64 bit Windows version. Though they need the 32 bit version of the plugin.
    If your DAW is installed in the folder Program Files (x86) (with that (x86) at the end), it is a strong indication that it is a 32 bit application, for which you would need the 32 bit plugin version.
    If your DAW is installed in the folder Program Files (without (x86)) chances are that it is 64 bit.
    Also, taking a look at the about page of your DAW (usually found in Help ➔ About) will most likely tell you whether it is a 64 bit application.
    More information about the differences between 32 and 64 bit you can find HERE if you follow the yellow arrow.
    Here are video guides which show the installation process of the plugin for some common DAWs:

  • Drag-and-Drop is not working.

  • Mac:

    On Mac this problem is only known to occur in older versions of GarageBand. An update of OSX and GarageBand has resolved this issue in all cases.

    Windows:

    Despite the fact that some DAWs simply don't support drag and drop (like LMMS for instance), this problem usually occurs only for some users who have a Windows user name containing non-standard Western characters. Like for instance, Asian or French names. There is a simple solution for that though.
    (Please let us know if your Windows user name does NOT contain such special characters, and the drag-and-drop problem occurs anyhow! The suggested solution below might work for you anyway.)
    The reason for the bug is as follows:
    In order to perform the drag-and-drop of a MIDI groove or fill, the plugin saves a temporary MIDI file called mtpdk.mid in the Documents folder.
    For some reasons, due to Windows updates, the file cannot be accessed by the plugin if the Windows user name contains special characters (the Documents folder is located inside the Users/[username] folder).
    Solution:
    At first, please make sure that you have at least the plugin version 2.0.4 installed, as this fix doesn't work with older versions. If you are not sure, click on the little question mark in the bottom right corner of the plugin to display the version number.
    Now for a quick fix, simply create a folder directly on your C: drive and call it MTPDK. So the path is C:MTPDK
    That's it! The plugin will now automatically use this folder for the temporary drag-and-drop file. Don't worry - this file is only a few Kilobytes large and will replace itself with every drop. It will not create any junk data.
    If this doesn't help to fix the drag-and-drop problem, please let us know by using the contact form on this page.
  • My DAW freezes for a while when I try to start the plugin.
  • This problem is known to occur on some Windows systems, if a certain option is enabled.
    1) Close your DAW.
    2) Go into the installation folder of your DAW, where you can find the .exe file of it. (For instance Cubase10.exe, reaper.exe, Studio One.exe, ..)
    3) Right-click on the .exe file and select 'Properties'.
    4) In the new properties window click on the tab 'Compatibility'
    5) Make sure that the 'Compatibility mode' is unchecked.
    6) Confirm by clicking OK and start your DAW and the plugin.
    Click here to see a video of this fix.
  • My DAW freezes when I try to close the project.
  • This happened on some Windows systems running Cubase or FL-Studio, but has been fixed in the version 2.0.8 of MT Power Drum Kit. If you encounter this problem, please download the latest version of the plugin.
  • I get the error message: The content file is missing!
  • Make sure to copy both files MT-PowerDrumKit.dll and MT-PowerDrumKit-Content.pdk into the same folder.
    Search all your VST folders and subfolders for another copy of the plugin. Delete it if you find any other copy. Within all VST folders and subfolders there must be only one single copy of the plugin installed, otherwise the DAW could happen to load the one which doesn't have the Content file on its side, which will cause the error message.
    In order to check that properly, just delete all files you can find of the MT Power Drum Kit plugin from ALL your VST folders and subfolders.
    Then go into the VST plugin settings of your DAW and re-scan the plugin folders.
    Make sure you don't find anything of the plugin anymore in your DAW. So, if you create an instrument track, MTPDK should not be available anymore. If your DAW still finds it, then search for the conflicting copy on your hard drive and delete it as well.
    Only when your DAW doesn't find anything anymore of the plugin, continue by downloading and installing the current version from the website.
    If you don't do this verification step by double checking and properly deleting before downloading the latest version, you can't be sure whether your DAW might still be loading the wrong copy from somewhere on your hard drive within your VST (sub)folders.

    If you followed the previous instructions and the error message still appears, the following guide could help to solve the problem:
    In some rare cases, if you have special non-English characters in your Windows user name (like Asian or French characters) and your VST plugins folder happens to be installed within your Users folder (for instance on the Desktop or in the Documents folder), then you should consider moving your plugins folder to another place on your drive. Make sure that the path doesn't have any non-English characters.
    Here is a simple suggestion:
    1) Create a new folder directly on your C: or D: drive, like: C:VstPlugins
    2) Move all your plugins from your old VST folder to this new created one (close your DAW beforehand).
    3) Go into your DAWs preferences and add the new plugins folder or change it to the new one. Hit re-scan if available.
    Although we are working on a solution to fix this bug in the plugin, we strongly recommend in general to not place your VST folder on the Desktop or in the Documents folder. They both are actually located within the Users folder. Having your plugins installed in the Users folder will put them to risk of data loss in case something goes wrong with Windows.
  • There is no SKIP button to skip the activation screen.
  • The SKIP button should be in the bottom right corner of the start screen.
    If it is not there, most likely your DAW opens an older version of the plugin which you might have downloaded already a few years ago. Within all VST folders and subfolders there must be only one single copy of the plugin installed, otherwise your DAW could happen to load the older version.
    In order to check that properly, just delete all files you can find of the MT Power Drum Kit plugin from ALL your VST folders and subfolders.
    Then go into the VST plugin settings of your DAW and re-scan the plugin folders.
    Make sure you don't find anything of the plugin anymore in your DAW. So, if you create an instrument track, MTPDK should not be available anymore. If your DAW still finds it, then search for the conflicting copy on your hard drive and delete it as well.
    Only when your DAW doesn't find anything anymore of the plugin, continue by downloading and installing the current version from the website.
    If you don't do this verification step by double checking and properly deleting before downloading the latest version, you can't be sure whether your DAW might still be loading the wrong copy from somewhere on your hard drive within your VST (sub)folders.
  • It doesn't work with GarageBand and Mac OS X High Sierra.
  • If you updated your Mac OS X to High Sierra, you might have problems with opening the plugin in GarageBand. This doesn't affect only the MT Power Drum Kit, but also any other 3rd party plugin. The error message says:
    'The Audio Unit XXX could not be loaded for your project, and may need to be updated. Contact the manufacturer for an updated version or further assistance.'
    Until Apple comes up with an update to fix this problem, you can try a workaround which is described here on this website.
    A second possible solution:
    If you can get your hands on a Logic version, you will be able to open your GarageBand projects there and all the plugins still work with the new High Sierra update. You should try the workaround from the link above at first though.
    Update:
    Apple has released an OSX Update in the meantime resolving this issue. Please look into that if you haven't already.
  • The plugin is crashing when I start it.
  • This happens on some Windows systems when the VstPlugins folder is located on the Desktop, in the Documents folder or in another subfolder of 'Users'. In this case, please move your VST folder to a location on your drive outside of the Desktop and 'Users' folder OR simply add a new additional VST folder in your DAW, which is located outside of Users or Desktop and place the plugin there. Restart your DAW or rescan the plugins folders.
    It is only a small bug which can be worked around as just explained. However, we are working on this to be fixed in the next update. Most people don't have their VstPlugins folder on the desktop or in the Users folder anyway.
  • The user interface i.e. the plugin window is empty.
  • If your DAW software finds the plugin and is able to load it, but the plugin window is empty and has no user interface, the following two solutions might be helpful.
    This happens in some rare cases on Windows systems, mostly on laptops with two graphics chips inside (for instance an AMD or NVIDIA high-performance chip plus a more energy efficient Intel graphics chip). You might not even be aware of having two graphics chips inside your laptop, because they are both connected to the same screen and video / HDMI outputs. Also, they operate in a similar way and the switches between them are made seamlessly by the system. You will find out whether or not you have such a hybrid system by following the steps in solution 1 or by checking your Windows device manager (Right-click on the Windows Start button ➔ Device Manager).
    Solution 1:
    Forcing your audio host software / DAW to use a particular graphics chip, instead of letting the system choose which one to use, solves the problem in most cases.
    Instructions for this process can be found here:
    Windows - Instructions for changing the graphics chip for a program.

    Solution 2:
    If solution 1 fails or you don't use a multi GPU system, you can download and install the following special edited version of the plugin. The drawback of this solution is a slightly decreased reaction of the UI in comparison to the normal version, but it is usable and will most likely solve the UI Problem.

Host Context
topIntroduction
Note to plug-in developers: implement support for these APIs to encourage host developers to add support for it.
Note to host developers: implement these APIs to encourage plug-ins to support them.

REAPER supports VST plug-ins (up to version 2.4 as well as version 3, though this document only applies to version 2.x). VST is a standard defined by Steinberg Media Technologies GMBH. To get the VST SDK (which you will need to implement VST plug-ins), you will need to download it from Steinberg, as we cannot distribute it.

It is worthwhile noting that while VST is a standard, it is neither an open standard (because you cannot easily distribute the SDK or things derived from it), nor is it a well defined standard.

This document will describe some REAPER-specific implementation notes for VST, as well as list some REAPER-specific extensions to the VST SDK/API that plug-in developers are encouraged to use to achieve great integration with REAPER. Additionally, we encourage other VST host developers to add support for these extensions, as we believe they are useful.


topImplementation Notes
REAPER currently implements a subset of the VST 2.4 standard as well as additional extensions-- this section discusses the former.
  • Audio/sample processing: REAPER will use processDoubleReplacing if effFlagsCanDoubleReplacing is set in the flags.
    REAPER will use processReplacing if effFlagsCanReplacing is set and processReplacing != process (if it equals it assumes that it is a faulty implementation of processReplacing). Additionally there is an option in the preferences to not use processReplacing for buggy plug-ins. Note that for plug-ins that have Cockos extensions (see below), the option (to not use processReplacing) is ignored, allowing known-good plug-ins to always run at full speed.
  • Threading/concurrency: Since audio processing can run in other threads from the UI, it's important to note what can run at the same time. REAPER is highly optimized to prevent UI and other actions from interrupting audio, so assume everything can (and WILL) run at the same time as your process/processReplacing, except:
    • effOpen/effClose
    • effSetChunk -- while effGetChunk can run at the same time as audio (user saves project, or for automatic undo state tracking), effSetChunk is guaranteed to not run while audio is processing.
    So nearly everything else should be threadsafe. For many things this doesn't mean having to do much, but there are plenty of plug-ins that barf when audio is running and you open the window (using effEditOpen). There is an option to bypass audio while opening the config window, but it sucks and shouldn't be required.
  • Dynamic parameters: REAPER can deal with the number of parameters for a plug-in changing on the fly. Use the extended host audioMasterAutomate callback described below to notify the host of parameter count changes (i.e. parameter X deleted, or new parameter Y), to preserve automation of higher indexed parameters when adding/removing lower parameters.
  • Multiple inputs/outputs: REAPER allows the user to dynamically connect input/output pins of VSTs wherever they want, so enable as much I/O as you need. REAPER also allows input/output counts to change, HOWEVER it is recommended that any changes you make be done from within processReplacing() or process(), and use the old value of numInputs/numOutputs until the next call. Additionally the initial value of numInputs/numOutputs should be set to the most common settings.
  • Longer labels: effGetParamName/effGetParamLabel/effGetParamDisplay all support up to 256 character strings (255+null).
topOS X: Cocoa Extension, 64-bit Support
REAPER on OS X is built using Cocoa and supports an extension which allows VSTs to create their UIs as Cocoa. Using Cocoa for UI of VST plug-ins within REAPER will result in a much cleaner integration, and has numerous advantages, including 64-bit (x86_64) support. We strongly encourage plug-in developers and other host developers to add support for Cocoa UIs via this API.
Note: on x86_64, REAPER assumes that all configuration windows are Cocoa, as Carbon is not supported.
When loading a VST plug-in on OS X, REAPER asks the plug-in if it would like to use Cocoa for its UI. This request is in the form of an effCanDo with the string 'hasCockosViewAsConfig', looking for the response of 0xbeef0000 - 0xbeefffff (the low 16 bits are ignored). If the VST has returned this value, all future effEditOpen calls will be passed with an NSView * as the parameter, rather than a Carbon window. The plug-in must track whether it has received a 'hasCockosViewAsConfig', and if it has returned the correct value. When adding a Cocoa UI, a plug-in should preferably add a single NSView to the passed NSView, via [(NSView *)ptr addSubview:myView] or similar.
An example plug-in implementation:An example host implementation:Note: the above implementation is similar to REAPER's; a host could also query hasCockosViewAsConfig prior to each effEditOpen, should it be cleaner to implement (avoiding the extra per-VST storage)
topExtensions
The following are extensions made available to VST plug-ins running in REAPER. Feel free to use them in your plug-ins, and encourage other VST host developers to add support for them.
A REAPER aware VST plug-in can respond to effCanDo 'hasCockosExtensions', with 0xbeef0000 (returning this value), which will inform the host that it can call certain extended calls.A plug-in that responds to 'hasCockosExtensions' may choose to implement any subset of the extended calls. Extended vendor specific calls the plug-in can implement include:
  • effVendorSpecific(effGetParamDisplay, parm, buf, val)
    Gets the formatted display of a particular value for a parameter, without setting the parameter. REAPER uses this when displaying the value of a VST's automated parameter on an envelope tooltip, for example.
    Example host-side implementation: Example plug-in-side implementation:
  • effVendorSpecific(effString2Parameter, parm, buf, val)
    Converts the user's string to a normalized parameter value, without setting the parameter. Reaper uses this when the user is manually editing an envelope node, for example.Calling with buf=' is a test for function availability.
    Example host-side implementation: Example plug-in-side implementation:
  • effVendorSpecific(kVstParameterUsesIntStep, parm, NULL, NULL)
    The plugin responds if the parameter is an enum, meaning that values move in discrete steps between states rather than smoothly.
    Example host-side implementation: Example plug-in-side implementation:
  • effVendorSpecific(effGetEffectName, 0x50, &ptr, 0.0f)
    Queries if the plug-in wants to override its instance name. If implemented, returns 0xf00d, and sets ptr to point to the name.
    Example host-side implementation:Example plug-in-side implementation:
  • effVendorSpecific(effCanBeAutomated, parm, (void*)(INT_PTR)sample_offset_in_block, value)
    Performs sample-accurate automation. Note that this should be used along with plug-in canDo of 'hasCockosSampleAccurateAutomation' that returns 0xbeef0000. This will be called one or more times in a block prior to processSamples. Returns 0xbeef if succeessful (sample-accurate automation is supported).
  • effVendorSpecific(effGetChunk,(VstIntPtr) named_parameter_name, buffer, buffer_size)
    Query the string value for named_parameter_name, return 0xf00d if supported.
  • effVendorSpecific(effSetChunk,(VstIntPtr) named_parameter_name, buffer, 0.0)
    Sets the string value for named_parameter_name, return 0xf00d if supported.
  • effVendorSpecific(0xdeadbef0, parm, rangeptr, 0.0)
    Queries the range of a parameter (allowing the plug-in to use more than the 0.0..1.0 range that VST defines).
    Example host-side implementation: Example plug-in-side implementation (in addition to responding to effCanDo/'hasCockosExtensions'):
  • audioMasterVendorSpecific(0xdeadbeef, audioMasterAutomate, listadjptr, 0.0)
    Informs the host that the parameter list has changed dynamically (new parameters added or removed within the list), so the host can properly preserve existing automation and other mappings to higher numbered parameters.
    Example host-side implementation: Example plug-in-side implementation:

topHost Functions
The following are extensions made available to VST plug-ins running in REAPER. Feel free to use them in your plug-ins, and encourage other VST host developers to add support for them.

There are some additional functions to enable better integration with the host, the primary interface for accessing these extensions is via the audioMaster callback. Suppose your callback pointer is named 'hostcb', then you would get each API with the following code: If an API is not implemented, hostcb() will return 0, and the resulting function shouldn't be called. Except when noted, all functions can be called from any context in any thread at any time. A list of functions defined:

  • GetPlayPosition() GetPlayPosition() returns the current playback position of the project. This is the time the user is hearing (and the transport shows etc). The value is in seconds.
  • GetPlayPosition2() GetPlayPosition() returns the current playback decode position of the project. This is the time of the audio block that is being processed by the host. The value is in seconds. This may be behind where your plug-in is processing, due to anticipative processing and/or PDC.
  • GetCursorPosition() GetCursorPosition() returns the current edit cursor position (if any), in seconds.
  • GetPlayState() GetPlayState() returns an integer value representing the project play state. 1=play, 2=paused, 5=recording, 6=record paused.
  • SetEditCurPos() SetEditCurPos() repositions the edit cursor to 'time' (in seconds), optionally moving the view if necessary, and optionally seeking playback (if playing back). This function should ONLY be called from a UI context (i.e. from the editor window, NOT from audio processing etc).
  • GetSetRepeat() GetSetRepeat() is used to change or query the transport 'loop/repeat' state. Pass a parameter of -1 to query the repeat state, 0 to clear, 1 to set, and >1 to toggle. The return value is the new value of the repeat state. ONLY use this function to change the repeat state from the UI thread (however you can query safely at any time).
  • GetProjectPath() GetProjectPath() can be used to query the path that media files are stored in for the current project.
  • OnPlayButton(), OnPauseButton(), OnStopButton() These functions control the main transport for the host app. Only call these from the UI thread.
  • IsInRealTimeAudio() Returns nonzero if in the main audio thread, or in a thread doing synchronous multiprocessing. In these instances low latency is key. If this is 0, and you are in processReplacing, then you are being called in an anticipative processing thread.
  • Audio_IsRunning() Returns nonzero if the audio device is open and running.
  • Additional API functions are listed in the REAPER Extension Plug-in SDK.
