Midi Guitar 2 and OneShot by Klevgrand

I would like to route midi notes to trigger oneshot samples but I don’t know how to set which midi channel that oneshot listens to for this. Particularly, I am using MidiGuitar 2, and I can successfully trigger other drum sets with it but am not having any luck with oneshot. Thank you for any help you can give!

On a slightly different note, I was in the Midi Guitar 3 BETA but it expired and I cannot get re-enrolled. Is this because it is to be released soon? I will have the same question above for MG3, in particular, can you assign Midi Out Channels?

Final question… in either MG2 or 3 in iOS. Can you “split” the keyboard in a sense? That is you can define an upper and lower part of the “keyboard” so that for example everything above A3 is sent to a particular auv3 synth and every note below it is sent to another synth? Thank you!
