Description

An 8-knob mapping device that has:

- The ability to save presets (8) (they respond to program changes 1-8 as well)

- Implements Ableton's API parameter mapping

- In parallel can be assigned to any MIDI CC value

- Can mute individual MIDI CC Outputs 

- Each parameter has a corresponding, editable label

I made this to have a "generic receiving device" for my Roto-Control, but the 8 knobs can be mappable via Ableton's MIDI mapping as well.

Very useful for my Roto controller. Thanks!

1.0.1 just uploaded, where MIDI CC is allowed to pass through, that way one can chain mappers for additional parameters.

1.0.2 up: fixed program change offset; added incoming pass-through of MIDI CC streams: the same CC assignments work for the output as for the input. For Roto-Control users: I did a few tests chaining multiple instances of Roto Mapper, basically, you can chain as many instances as you can have discrete CC assignments, then save each instance as a preset (.adv version), RENAME each instance, then you can have discrete mappings and customize labels etc for each; then you just need to control the presets on the first instance and it will automatically recall all the other instances as they'll be chained via program change messages.
