I'm trying to set up a Key 61 to receive Program Changes to change sequences. I'm using OnSong 2022 on my iPad to send the PCs on channel 1 over Bluetooth.

OnSong is simultaneously sending Program Changes on channel 6 to a MorningstarFX MC3 (to go to the correct bank) and through the MC8's MIDI THRU to a Boss RC10R on channel 10.

The problem seems to be that the Key 61 is seeing the messages on Channels 6 and 10, which are not meant for it, and reacting to them. The result is that the Key 61 consistently goes to the wrong sequence for every song.

Is there a way to have the Key 61 filter Program Change messages so that it only responds to PCs on channel 1?

By the way, it doesn't have to be channel 1. I can use any channels except 6 and 10.

Any help would be appreciated.

I think MPC firmware react to PC messages on any channel, it's omni for this type of messages ( MMC, Program Changes, etc..) You would need to filter the PC messages, at the output of the Ipad, before the MPC USBMIDI or Din Midi input, you could do this with a Midi splitter box that gives option for filtering by channe, sending PC Channel 1 and 6 to the other devices, but only the desired "MPC sequences" PC messages to the MPC....

Yes, I understand all of that. That is the exact problem : The Key 61 listens on all channels. But OnSong is sending to the two other devices on a wired connection and to the MPC over a Bluetooth connection. I don't know how to put a filter into a Bluetooth connection.
