Avast Thar Mateys!
Indeed, ye can only set one MIDI channel for an entire setup, currently. But, there is a change in the wind and tide coming. Me Pyrate ears have heard a rumor on the winds that a pototype of a new chip is being tested as we speak in low whispers of our desires. Rumor also has it that Independent channel assignments is in the package. But beware of what you wish for. Keep your voices low and let Inpector 109, Chris DeHaas, Kim, Gina and the rest of the fine folks at Zendrum work their magic. Savvy!
