First you need to convert the CC to CV using the Midi-CC module. MindMeld ShapeMaster can then be used to convert the linear curve to log. ShapeMaster needs to be in CV trigger mode so the playhead position is controlled by unipolar or bipolar CV rather than playing left to right over time.
Check out this video about it from Jakub. Watch the first couple of minutes for some context then you can skip to minute 6 where he shows how to do this specific kind of voltage remapping - he has actually made presets for Lin to Exp conversion (you can invert and reverse the Lin to Exp preset using the buttons above the curve to get a Lin to Log curve if that’s what you want).
This post/response actually ended up solving some similarly unique Hardware CC —> CV manipulation needs of mine as well. ShapeMaster is an amazing module and the simple CV tracking mode solves so much for me. Thanks to all!
Brilliant, cant wait to do some tweakin and remapping my hardware cc’s…thanks for the awesome modules, i use so much nysthi stuff everywhere in my work!
