Just got another hour in testing 4.2 and I have to say well done.
Just one issue with the Velocity Curve though. I've saved my curve into the default patch and it's loading when the keybord boots up, but there is still this random full volume spike on note velocity when the keyboard is played.
To stop this from happening I have to select the any of the other curves, and then go back to the default one and then the response from the keybed is always correct.
Everything else seems to be working like a dream. The effects are being recalled on bootup and the COMBI mode it running very well for me.
