Hi all! For my piano set-up via AUM on iPad I have my Ravenscroft piano AUV3 plugin loaded 2 times: 1st is a normal piano, and the other one a +12 transposed piano. These go together into a piano bus channel where I load effects unto it. And where I control their volume together. The transposed piano also has it’s own volume, since I normally only play the normal piano, but then I sometimes like to mix some of the transposed piano into it.

However, for the sake of CPU, I was thinking of combining the MIDI signals so that I could just use one instance of the Ravenscroft. The challenge is that I don’t just want to turn the transposed piano on/off, but I would like to mix it in with a knob..

My idea is to split my keyboards midi signal into 2 midi channels, 1 going into the Ravenscroft right away (let’s call it channel A) and the other going through an app like Mozaic first and then to the Ravenscroft app (let’s call this one channel B).

Then were I get stuck; is it possible to make a ‘volume’ knob for channel B? I guess it would sort of have to make the general MIDI velocity go up or down? I would like to still be able to play soft or loud so the sound is still adaptive to my playing.

In Ableton I saw someone achieve this same goal using the Chord Midi functionality that’s in there. Hope anyone can help me out figure out how to do this on my iPad! Thank you!
