I'd like to control the preset change of my amp and another device from the Nova System. Can the unit transmit on 2 separate channels?
The unit can only transmit on 1 channel, but it can also transmit on all channels at the same time if you set the MIDI channel to OMNI in the MIDI SETUP menu.
The Nova System will send the same message to all channels. You can still control both devices, but they will receive the same messages, so you'll need to program these devices accordingly.
