  • Install Info for Windows OS

  • VProm can install both VST3 and VST2 formats in 64bit and 32bit versions, next version 3.0 will drop 32bit support.


    You can choose to install/remove the VST3 version or not after learning about a possible issue with that format bellow.


  • Install Info for Mac OS

  • VProm can install both VST3,VST2 and AU formats in 64bit and 32bit versions, next version 3.0 will drop 32bit support.


    You can choose to install/remove the VST3 version or not after learning about a possible issue with that format bellow.

    • If using Logic Pro or audio-unit reboot your Mac or session once after VProm installation.
    • In Logic Pro if your MIDI input device seems unresponsive and not triggering VProm be sure to untick MIDI 2.0 in Logic's Preferences/MIDI tab.

  • Mac Native Silicon support (M1/M2)

  • Mac version is available as AU (Audio Unit), VST3 and VST2 formats

    Native ARM Silicon (M1/M2) version is in the making for VProm 3

    I have many users using Silicon Mac with VProm already because while not native ARM yet it is nevertheless perfectly working using Apple's Rosetta 2 compatibility feature (only needed for VST format). AU format should load fine without doing anything else as an emulated compatibility layer is automatically added when needed.
    By the way, many of my plug-ins are already available in native Silicon format being Universal binary 2.0 (Silicon/Intel), you can monitor all plug-ins format status right here

    So to be clear, unless you are using the AU version (AudioUnit) which some DAW like Cubase unfortunately does not allow then you are forced to use the VST format. In this case it won't be automatically enabled with Apple Rosetta 2 and you need to enable it yourself.

    Opening your DAW in Rosetta mode:
    • Close your DAW.
    • In Finder, open the Applications folder.
    • Right-click your DAW's app icon.
    • Select Get Info from the popup menu.
    • Check the box that says Open using Rosetta.
    • Open your DAW. You can disable Rosetta later by doing the same and unchecking this box.
    About Rosetta 2
    Rosetta is a program that enables apps built for Intel-based Macs to run on Apple Silicon-based Macs. Rosetta works in the background and automatically translates the app for use with Apple silicon. You can also use Rosetta to translate Native M1 applications, such as Logic Pro X, to run as it would on an Intel processor. This may help with compatibility issues in certain cases. In most cases, you won't notice any difference in the performance of an app using Rosetta.

  • VST3 Known Issue

  • VProm 2.0.4 is using an older version of Steinberg's VST3 SDK which might have issues on state initialisation


    This problem can cause parameters reset in some DAW, the VST3 could also crash on loading notably with Ableton Live, this will be corrected in the future with a brand new VST3 format arriving with VProm 3.
    For now VST2 version is rock solid and is the one to use.
    If you experience problems you should remove the VST3 entirely from your computer, a DAW might not offer choices between both installed formats and would load VST3 by default. To delete VST3 version simply locate VST3 path location then delete the VPROM.vst3 file that is inside.
    VST3 Path:

    • Pc: C:\Program Files\Common Files\VST3
    • Mac: Library/Audio/Plug-Ins/VST3

    Note that unlike VST3, VST2 can be installed anywhere on your machine so be sure that your DAW is pointing at the right path, the standardized path is usually this:
    • Pc: C:\Program Files\Steinberg\VSTPlugins
    • Mac: Library/Audio/Plug-Ins/VST


  • Usage Info

  • As you probably already know VProm can also load external sounds in the form of original EPROM chip data dumps also called binary images which VProm can read and decode thanks to emulated DAC per voice following the original ULaw compression format used at the time. You can find some ressources about that at the community/download section..

    You can also make your own (see manual) and in the future version 3.0 you will be able to do so from the plug-in directly.


    note: If the X16 oversampling is used at a project sample-rate of 192Khz or higher no sound will be produced.


    MIDI pitch-bend can act as a "global transpose" offset for all sound playing rates (tuning).


  • Coming from previous versions

  • VProm's variable sample rate engine have been enhanced for version 2.0.4. In order to test this and hear it for yourself, please go to the SET page and trigger the tambourine, try with X16 on and off, change tuning and hear how the harmonic structure is better maintained with X16. I would rather use either TAMB, HIHAT, CAB and EXTRA EPROM slot to load custom cymbal type sounds or any sound that would contain high frequency energy simply because other slots like BASS or SNARE doesn't use X16 internally.


    There is a new CHOKE function which will stop the EXTRA EPROM playing instantly, usefull for choking cymbals... it is triggered by MIDI note C4 and will be displayed on the EPROM playing status in real time.

    Funny note, a choke switch was actually added to early Prince's LM-1 drum machine, you can for example hear it choking cymbals sample on the 1999 LP song "Automatic"



  • Note if you upgrade from the deprecated Windows only 32 bit version 1.0

  • VProm 2.0 is a complete rework so no preset sharing between v1.0 and v2.0 are possible.
