Hi Mike,
Check out the TS-7300. It has 10 RS232 ports. by default (TX/RX only
on 8 of them). 8 of the serial ports are provided by the FPGA, and it
should be possible to send the serial to the multi-pin header to be
converted into MIDI format (i'd recommend adding isolation to each
interface). There are around 50 free io lines connected to
the FPGA, so in theory you should be able to do over 20 MIDI links
from the base board.
The software for the FPGA is free from Altera, and Technologic
Systems can probably provide you with a minimum FPGA configuration to
talk to the main CPU...
It sould be possible to get the MIDI ports to run at 31.25kbps by
changing the input clock to a standard serial FPGA block.
Regards,
Peter
