EDIROL UM-2Ex, a MIDI 1IN/2OUT interface with USB 1.1 connection. YAMAHA UX96, equipped with a serial port compatible with the QY series, supporting control of up to 96 OUT-32 IN MIDI channels. These are old and scratched MIDI interfaces. They probably work, but I can't guarantee it. The YAMAHA UX96's MIDI OUT has 16 channels, and the "TO TG/INST port" serial port has 80 channels. It's compatible with the serial port of the company's gadget sequencer QY series, but I think it's difficult to send and receive data with a current PC. You can find information on the manufacturer's websites by searching for them. Thank you.
