[comp.sys.atari.st] MIDI-control

A089FLUM@HTIKUB5.BITNET (08/26/87)

1st question: I'm writing a program in GFA-BASIC to control my MIDI-devices
 (YAMAHA DX21,RX15). Of course I have timing problems. I'm searching
for an interrupt-routine which is exact to the millisecond. Can
somebody help me?
2nd question: This program will control (at the end!) 4
MIDI-synthesizers of different types (I'll have to borrow them!). In
order not to get into problems with different codes controlling
wheels, key-velocity etc. I'm looking for an exquisite list with
differences of all kind of MIDI-synth-types. (At last a STANDARD?).
Help!

Thanks in advance
