I got the minimal control surface working and I’ve uploaded the default patches. I’m really impressed by the sounds and I can’t wait to finish building the full control surface! I just wanted to say thanks to TK and everyone who made this possible. I realized today that this is a very complex sound engine and it does more than my XV-5080 or even many of the plugins I’m used to. You can do crazy modulation tricks like Massive, I’m totally blown away!
Thanks for the feedback! 
It’s always nice to read that somebody experienced that the MBSID engine is doing “a bit more” than just forwarding MIDI events to SID registers.
Best Regards, Thorsten.
