I got a Launchkey 37 for Christmas. I’ve been looking to see whether I can reasonably use (just) it for gigs, since I’ve been playing keys on fewer songs lately. After going through a few songs, it seems clear that I’ll need to do quite a bit of octave shifting in songs. I’ve tried connecting a switch widget to the MIDI In Transpose, but have been having a hard time understanding how to use scaling to change an octave and wanted to verify what I think I know. Through trial and error, it seems that min scale of 50 and max scale of 54.8 gives me the initial key and one octave up when I switch. As best as I can come up with, transpose goes from -127 to 127 (I see that when I press the widget when I don’t change the scaling), so the 50 makes sense that it would be in the middle - 0. And that would mean the 54.8 is 54.8% up the range of -127 to 127, which would be about 12.19 and I guess gets rounded or truncated to 12?
And after all this, I guess I should ask if this is the best way to be shifting octaves in songs/variations.
