Hi. Worth checking, but no, I am very sure and have checked routing, MIDI, audio, everything. Just a straight up vanilla synth insert. Tried with both simple instrument track and split MIDI/Audio. Another loaded the same way before or after, works straight away, as expected. With AL2 nothing seems to make it respond to MIDI or generate any sound if played from its own onscreen keyboard. I think something got corrupted somehow in the initial install and now it's stuck in there somewhere, in the registry or wherever. I don't have time to go bananas troubleshooting it right now, plus I can use it via Komplete Kontrol if I really feel I need to, so I'm just leaving it alone for now but I guess at some point I'll get back to it, try a deep uninstall with Revo or whatever.
