200e

Hi Don

Yes, that is what was happening yesterday. Inspired by Tom's advice (thanks by the way Tom), I just had a session, and I seem to have isolated the phenomena as being linked to the Modulation Oscillator. 

That said, the Twisted hardware is behaving the same way! So perhaps this is just a quirk. 

Anyway if you're curious, here is what I am doing: mod type set to Morph, morph set to 5, tables set anywhere between 2 and 5 and setting the Mod Osc to say 220 and on high range. Now as I turn the Mod Osc's FM in (sans patch cord), I can sometimes hear changes, but looking at the green and red LED's either side of 'morph' reveals some definite changes as the FM in pot is rotated. And when this happens, it seems to occasionally have a knock on mirror effect on the Principal Oscillator's FM in knob.

Being 'green' to the 200e, I am probably making a glaring omission of some kind. Sadly despite the reset, the volume level on the Complex seems way lower than the Complex. I suppose I could ask B&A about that, though I run the risk of being tagged a pedant! 

Cheers
Rash
