Modulation (now v high)
Delay time (now v high)
Oscillators 2-4 (all now about an octave lower than before)
There may be other changes (perhaps filter spacing) but I'm less sure about these.
I can reset them by turn the knobs right down then back up to the desired setting but this is a pain, particularly as I'm v particular about my oscillators all being precisely in tune,
Problem seems to have started after midi syncing to other kit but remains now

Does anybody have any idea what has caused this strange behaviour and how I can make my Matriarch well behaved again?
