* Improve the midisyn layer a little. * Add a driver for the Yamaha OPL[23] FM synths. The opl driver is not finished yet; it sounds pretty awful. For some strange reason I cannot get any FM sound from my SB64 cards, but a regular SB16 works fine.
Make sure there is no outstanding timeout when the sequencer is closed.
It handles decoding of MIDI commands, voice allocation, and translation it notes to frequencies.
