Sorry to tell you that is not what I mean. Of course I've read the manual, and I know how to access all the front panel controls using the Data knob. That's easy.
I'm talking about hidden parameter controls. I've added over 45 extra synth/global controls to my AN200 that aren't listed in the manual, these were all found by digging deep into the back of the manual and working out the sysex.
If you know how to make the sequencer play in modes other than Forward and Rev, then I'd love to know.
