Hi,
I'm not trying to be funny - but I don't really see that much of a reason for the MIDI transform tool.
For example - isn't it easier to just use the freehand tool to re-draw your CC data the way you want it? Rather than enable the transform tool, pick the right selection, work out what you're doing, drag the correct corner...
I'm sure it's just me, but I think it's easer to just use the smart tool and re-draw CC data, or volumes (which overwrites what's already there).
Hopefully, I'm missing something - and there is a more useful reason to have this tool
