Now my go-to expressive lead app. – Ribbons : Touch Instrument Review

This is the control I've been waiting for. I'd like to see a stack of 1-3 vertical sliders on your choice of left or right, color settings, and the ability to assign anything to a slider or Y. A second keyboard above with it's own settings incl. height and pitch offset would be great too. My only complaint is that notes begin on standard pitches even with 0 snap set. Even better than the positive/neg slider would be separate pos/neg amt-amt sliders each with their own y-axis center, or just freehand a vertical levels wave for each parameter. This would truly single out Ribbons as the most expressive live controller possible (unless you want to add four y-level assignments, for each ADSR phase). That would be the ultimate control this app is heading towards. Public domain KRPM.
