It is true, I’ve just tested it, as Timbre was not working for me. After I set it to cc71, it works. Here’s from the Surge manual:
Timbre is a modulator used primarily for MPE controllers. It takes the midi CC#71 (timbre) and applies it as a voice-level as opposed to scene-level modulation source. This allows the MPE convention of one-note-per-channel to take an otherwise scene-level midi parameter (CC#71) and turn it into a voice-level modulator.
Would be nice if they followed the convention of using cc 74. Thanks
