@Christoph-Hart OK I tried your example code from the other thread on Glide (from 2017)-- and it isnt working correctly at all for me...it mostly not working at all to be honest.
In fact it also breaks any sustain processing as well... hmm this really needs addressing at a systemic level.
what would be simplest would be Synth.addPitchFadeFromTo(ID, startNote, endNote, time)
