The latest mt32-pi release has added support for USB serial devices - making it much easier to connect retro gaming PCs via serial cable. Previously we had to use a clunky RS232 to TTL converter module. The new setup is much cleaner.
What you need
A new configuration option
usb_serial_baud_rate has been introduced. You’ll need to edit the mt32-pi configration file (
mt32-pi.cfg). Replace the following line:
usb_serial_baud_rate = 31250
usb_serial_baud_rate = 38400
The PC serial port can’t run at the standard MIDI baud rate of 31250bps. Instead we tell our mt32-pi to use 38400bps – the closest “PC standard” baud rate.
Other than that, the setup is identical to the previous guide. Enjoy!
