Simplified SoudFont:

MPTK is designed to be used for gaming with weak devices which implied some choices.

  • Some instruments in SoundFont, are using more of one waves to play one midi event. MPTK will plays all the waves associated to the note or only the first found. A parameter lets you make your choice.
  • Panoramic sounds are defined in SoundFont and in Midi files. For some games it’s better to manage right/left (for example to localize an object). A parameter lets you make your choice.
  • Complex SoundFont effect are not yet implemented (reverb, chorus …) to avoid high CPU impact. Could be added in a future version. Have your say!
