Sunny Synths Korg MS20 patch mapper

The panel is a pure patch mapper as the Korg MS20 does not support the load/save of programs or the manipulation of its program parameters by Midi NRPN/CC/Sysex messages.
It will support you in saving and retrieving Korg MS20 patches on your PC but gives you also the possibility to exchange them with other users as they are stored as sysex files.



  • Korg MS20 interface with same look and similar way of working as actual synthesizer

  • Button to switch the layout between the different colored editions (black, blue, green)

  • Top row of support “screens” with old look

  • Visual feedback by using “LED” ring buttons and indication of the value (on change or on click)

  • Envelopes graphs handled by mouse or buttons

  • Load / Save programs from individual .syx files

  • Easy program renaming

  • Display and export of program parameters as text file

  • Ability to describe 9 input/output colored patch cables with different sources/destinations

  • Patch cables drawing directly on main panel with adjustable transparency level

  • Ability to display full cables or cable plugs

  • Extra input/output patch points from/to external synths, sequencer and FX chain

  • Programs have a name, author, save date and description. They can be associated to a category

  • Browser of the files on the disk

  • Patch sheet tab with patch sheet for Korg MS20 and other gear (external synths/sequencer/FX)

  • Automatic reading of wav files associated to a patch

  • Manual/Automatic reading of any wav file

  • Standalone versions for PC and Mac

  • VST versions for PC (32 and 64 bits)

  • VST and AU versions for Mac

  • All buttons associated to a Midi CC controller number so you can adjust them from a hardware controller (still no impact on the synth of course and unfortunately)


Price: 14 EUR
