UNO as midi interface?

[pedech]

Hello.

I am using the UNO as a midi interface for my iPad. Meaning, I connect a hardware synth to UNO’s midi out and connect UNO to my iPad.
Works great - the iPad controls UNO in channel 2 and the hardware synth in channel 1.
However, when I turn UNO knobs it affects not only UNO’s preset but also the hardware synth’s preset.

Question: is there any setting for UNO’s knobs to control only its own sound without sending out any CC’s to midi out while still in use as a midi interface?

There is a setting for sending (or not) the 'Program Change', but it sound like you are having problems with CC messages. UNO only sends these on the channel set on the device (there is a channel for receive and a channel for send), double check that you have set BOTH appropriately.

For example I have mine set to Channel 5... which actually comes out as 4 as Midi counts 0 as a channel.. here's a log of of me turning knob of OSC1 Tuning.

It could also be that the hardware Synth is listening on all channels (Omni mode on), try seeing if there is a setting for turning that off.
