MONSTER Keyz, Mix n Match Your Dream Keyboard Sound!

It's a FREE VST with Various Keyboard Sound for Music Arrangers and Music Producers!


Monster Keyz is a selected keyboard sound specially programmed by me for my own personal use but I decided to give it away to people!

It’s a ROMpler VST, meaning you use the sounds as it is. No tweakable parameter (yet) except individual Volume, Pan, Master Reverb, and Master Volume.

Here are the complete features of Monster Keyz:

  • Simple GUI / easy to use.
  • Every sound is unique because each sound is programmed and sampled from scratch.
  • Mix and match 30 built-in sounds to come up with hundred combinations of sound (wall of sound).
  • Very little RAM usage.
  • Simple parameter, only Master Reverb and Master Volume exist (and Level Meter too).
  • Major plugin format: Windows 32bit DAW and 64bit DAW, Mac VST, and Mac Audio Unit (AU) so it can be used in the majority of DAWs (Sorry, no support for Pro Tools, but you can use VST to AAX converter like Blue Cat’s PatchWork).


Here are a few tips when using Monster Keyz:

  • Try to combine a Piano sound with Choir and/or Pad or everything else. You might get a little surprise!
  • Save your favorite sound as Preset on your DAW software.
  • When combining many sounds, don’t forget to adjust the volume/balance of each sound.
  • Use Pan Knob creatively. Put Synth Brass on the left and Choir on the right or do what you want to do!


Right now, there is no installer/setup file so users have to do it manually :

  1. Download the main Zip file based on your DAW (64 bit or 32 bit) and your OS (Windows/Mac):
    • VST on Windows or Mac: Cubase, Nuendo, Ableton Live, Bitwig Studio, FL Studio, Studio One, Reaper, Cakewalk, Mixcraft, Reason, Tracktion, etc (Don’t forget to check if your DAW is 32 bit or 64 bit too).
    • Audio Unit (AU) on Mac: Logic Pro, GarageBand, Studio One, Ableton Live, Reaper, Digital Performer, etc.
    • RTAS or AAX: Please use VST to AAX converter like Blue Cat’s PatchWork.

  2. Unzip the download file from step 1 and put it on your virtual instrument folder:
    • Win VST 32 bit folder:
      • ‘C:Program FilesCommon FilesVST2‘ or
      • ‘C:Program Files (x86)Common FilesVST2‘ or
      • ‘C:Program FilesVSTPlugins‘ or
      • ‘C:Program FilesSteinbergVSTPlugins‘
      • Or any VST folder according to your DAW (Check your DAW setting).
    • Win VST 64 bit folder:
      • ‘C:Program FilesCommon FilesVST3‘ or
      • Or any VST folder according to your DAW (Check your DAW setting).
    • Mac VST 64 bit folder:
      • ‘Your Mac HD/Library/Audio/Plug-ins/VST‘ or
      • ‘Your Mac HD/Library/Audio/Plug-ins/VST3′
    • Mac Audio Unit (AU) bit folder:
      • ‘Your Mac HD/Library/Audio/Plug-ins/Components‘.


Apple / Mac now have tightened their security on their OS. So my VST sometimes get a red flag or identified as a virus or malware or Mac marked my plugin as damaged.

If you need to believe me, please check my personal web here: and, I’m a music producer and Steinberg Certified Trainer and making FREE VSTs are my passion.


For a software or plugin to be notarized (=not flag as danger software or viruses or malware), I have to pay Apple some amount of money yearly. And right now, I’m not doing this (paying them).

So the solution is to use the terminal trick explained here:

Or watch this :

And my friend Agung Putranto has been kind enough to share what he did to make my VST shows up in his Logic Pro 10.7.1 on Monterey OS (This trick maybe work on earlier Logic Pro version and on BigSur OS too) :
