I've recently learned thanks to "ipressthebutton" that there's an older Midimate version that allows 10 IA's in Controller Mode, so I contacted Rocktron and ordered the v1 firmware EEPROM for $20 plus $5 shipping (lower 48, USA). The Midimate's EEPROM is socketed, so replacment is easy by just taking static precautions and putting it in facing the correct direction etc.
