Hi All

I have the following configuration.

computer(com2) -> ccibm cable -> TO HOST port on TG100 -> TG100(MIDI 
out) -> MX80(MIDI in) or DKC5R controller -> MX80.  And it plays fine.  
However, I used old computer that has serial port.  I was wondering or 
if anybody tried USB to serial converter.  Ultimately I want to use 
laptop or computer with USB port with the following setting.  BTW, the 
TG100 only say MAC, MIDI, PC1 and PC2.

So the configuration will be laptop -> USB to Serial converter -> CCIBM 
cable -> TO HOST port on TG100.  Is this going to work?

Any feedback is helpful and appreciated.  Thank you.
