Test 1 has them all set pretty close -- solo'd -1 oct on all three. For the MSG, that means using the dedicated sub octave switch. For the PF that's soloing voice A, with filter around 20, resonance at 0, depth at about 50, sensitivity at 45 to give it movement similar to the OC-2.
For
test 2 I tried to differentiate the units a bit more. The OC-2 had -1 and -2 oct dimed. MSG added the square wave at unison, plus the intelligent ring mod tune dimed. PF put filter at 20, filter resonance at 7, depth at 55, sensitivity at 55.
