RdPiano RdPiano

RdPiano accurately emulates SA-synthesis digital pianos, such as the Roland MKS-20, RD1000 and the Rhodes MK-80 electric piano. It simulates the CPU-B board reused in different models, emulating the CPU and the custom chips. The emulation of the custom chips is derived from silicon analysis. It also approximates the BBD chorus and tremolo effect, albeit less accurately than the digital emulation.

NOTE: Due to a bug, it's possible for some versions to produce no sound when first loaded. To fix it, please change the current patch at least once.

Having trouble with MacOS? You probably need to run this command on a terminal:

sudo xattr -rd com.apple.quarantine /Users/<yourusername>/Library/Audio/Plug-Ins/Components/rdpiano_juce.component

Content

  • rdpiano_juce: a plugin (VSTi/AU) version of the emulator, to be used with DAWs
  • librdpiano: a dependency-free version of the emulator, to be used as a library in other software, also builds a test standalone app with SDL
  • re_stuff: tooling used during the reverse engineering process, mostly for educational purposes
