Baud rate is the number of changes per second.  Thus 9600 baud can transmit
at 19200 bits per second if each frequency transmitted can represent 2 bits
of information.
e.g.   frequency 1 encodes 00
				 2         01  
				 3         10
				 4         11
then a 9600 baud can transmit 19200 bits of information.  So it is possible
to have RS232 talk to MIDI if somebody can come up with such a protocol.

How about using RS422?  It is standard on a Macintosh and as far as I know,
it can handle serial communication well beyond 32Kbps.  Any suggestion?
I bring this up just because I have one myself and would like to make use
of it.

Anybody out there know if it is possible to upgrade a Poly61 to be MIDI
equipped?  Or simply does it worth it?  The sound is great but since it
does not has velocity sensitive keyboard, it will not be able to generate
these MIDI commands for transmission anyway...

Thanks in advance for any information you may suggest.
