The GM5 ("give me five") is Ploytec's second MIDI chip in its company history, and already used in a number of existing USB MIDI designs. It's a USB2.0, class compliant, configurable single chip solution and works on Windows XP, Windows Vista, Windows 7, Mac OS X and Linux without the need of any additional driver software. The GM5 does all combinations from only MIDI In or only MIDI Out to up to five MIDI Ins and five MIDI Outs working simultaneously. An optional 24C04 EEPROM can be used for customized USB VID/PID, product strings and channel count.
