AU-300 is an Audio Unit Plug-in-based MIDI-Programmer for some famous Japanese synths from the Mid-'80s. It brings the modern DAW based working process together with the analogue sound of the Roland Alpha Juno Family.


  • Load it in your AU-Host and control the Alpha Juno or MKS-50 just like using a softsynth.
  • All settings are saved in the project file (and restored on load).
  • All parameters can be modulated and automation curves can be drawn.
  • You can save and restore .aupresets files and manage them on your computer.
  • If your Host is supporting MIDI learn, map your controller to it. This is usually only possible with Sysex-capable controllers.
