Roland A-880 MIDI Patchbay
Roland A-880 midi patcher and merger to interconnect MIDI devices (e.g., my synthesizers, hammond, etc) but also to connect these instruments to my computer using the simple Roland UM-1G USB MIDI interface. This allows to record MIDI into the DAW or to play MIDI files from the DAW while using my synthesizers as sound source. The Roland A-880 allows to patch 1 MIDI channel to 1 or more other channels. However, only two MIDI channels can be merged.

I have a master midi controller on Channel 1 going into the A880 and then out to 7 synths and a drum machine.
They are all on different midi channels but sometime I want to play the exact same thing on 3 synths (stacking the sounds) and then other times I want to play them one at a time
Is there way to do this with the A880?
Not sure if I understand your question. Your controller is on channel 1 then you mean Midi Input 1 on the A880?. If your midi controller sends on, for example, midi channel 3 then only the synth synth that receives on midi channel 3 will play. If you want 3 synths to play on midi channel 3 then you need to set the midi receive channel to 3 on each of the synths. There is no way of doing this with the A880.
