SIDaster midi implementation chart

This section describes the Midi messages to the one SIDaster synth is responding.

Midi Notes

  • Note On and Note Off are supported forthe range C1 to #A7.
  • Note On “0 Velocity” messages are handled as Note Off (which is a specific case of Midi specification).
  • Memory of the last note pressed is maintained.
  • Patch management is handled through Midi keys C0 to bB0, see SIDaster Patch Data

To Do

  • Enhance channel Filtering
  • Update Midi engine to manage three concurrent Key press (up from two)
  • Add Pitch/Bend support
