Hmm still no luck with Sysex chase disabled and Reset on Stop disabled.
The col legno articulation can also be triggered with a high mod (CC1) value. Pizz is triggered with a low mod value. I’ve added a low mod automation point in the part, and yet it still triggers col legno for some reason when I move the playhead to different parts in the track.
Might there be some way I’m triggering a high mod value with the expression maps that I don’t know about?
