@Dan Reynolds… hi Dan ! I am no coding expert but am very excited by / and hacking my way thru Timesynth and other audio stuff . . have acheived most of my goals but last thing to confound me is I can get midi in / thru from Ableton - and back, or play a synth in Unreal FROM Ableton, or drive Ableton audio from a midi file in a Blueprint - but I cannot for the life of me work out how to play a synth in Unreal with a midi file in a blueprint …thnx in advance !!
