Arpeggio synth sends notes on midi channel 2

I have organelle hooked up as part of the rig where Beat Step Pro is the master - I already changed the midi in and out channel to 3 in the mother pd , so it doesn’t receive form / send to all the midi channels - in the arp synth patch however it conforms to the BSP tempo but sends out arp messages to channel 2 - tried to change that and changed the noteout object in the arp pd, but it doesn’t work - any idea how to do that would be much appreciated.
