I recently bought an Assimilation MIDI conductor and it does not
seem to work with Macterminal or Versaterm. I plug the connector in the
modem port, then the modem in the side, I didnt hook up the synth but
why should that matter. Both programs hang whirring the disk with frozen
cursor. They say in the book that If there is no power on the synth it will
default to RS232. I dont think this thing works!. Any luck, Anybody?

Any luck, Anybody? > > {ihnp4|allegra}!cmcl2!acf2!gossc I've had the same problem with the OPCODE Midi interface. Attaching it may set up the port in such a way as to invalidate RS-232. Another problem is there is a bug in the old 64K ROMs such that mouse tracking is a problem with the OPCODE Midi interface .... it may be similar in Midi Conductor. Opcode sent a fix for this. This is not a problem with the new ROMs Ed Moskowitz ihnp4!ihuxm!em

Assimilation is out of business. I think that connector (I know the people who designed/built it for Assimilation) was set up so that if there is POWER on the device connected to the RS 232 port, it would default to RS232, ie, an Imagewriter connecter, turned on works ok, turn it off, you have MIDI The frozen system is a common symptom (I am writitng a CDROM driver, running at 1 meg baud rate). It usually happens when you get I/O interrupts at high speed (MIDI is 31.25K baud). High speed usage should have interrupts turned off. I assume the little box is sending nulls at 31.25k baud which the system is tryining to process. Need any more help, please let me know Phil Hunt ..calma!sivax!phil
