[ATTACH=JSON]{“data-align”:“none”,“data-size”:“full”,“data-tempid”:“temp_116366_1504745357214_474”}[/ATTACH] Here’s what I had to do to get elindell’s example working. It seems that, at least when triggering notes this way, either the synth’s output has to be killed or you have to wait until the release tail of the note is completely finished. In fact, I think on elindell’s example if you hit J and wait for the sum duration of the ADSR envelope, then hit K, you’ll get the new velocity (I could have misremembered that; started tweaking straight away, sorry!).
I hadn’t noticed this as a problem because my (now fairly complex/gnarly) synth BPs are managing NNAs - new note actions - pretty strictly, and the synthesised elements of my music system have mostly been using subtle velocity ranges and some LFO/Timeline-modulated oscillator gain levels, making this hard to spot.
Keen to hear how people get on, and what the official word is on it!
