It works as expected here.
- try maybe do this at REV2 itself and check parameters become as expected eliminating software editor
I did a Basic Program A to start with
- changed to Gated sequencer
- moved the knob for sequencer to get to seq 2
- moved parameter knob if not already at destination, to destination
- the value is off at this time
- move parameter knob to step 1 to 4 and enter values 88, 0, 80, 0, and step 5 to Reset
- move source modulation knob, up to left, to slot 1, set source to seq 2 and dest to cutoff, value remains 0 for now
- press mode button on sequencer and value until saying keystep
Now pressing keyboard key I hear no difference
- move mod knob to slot 1 and parameter to value of slot 1
- move values down at -40 and below while pressing keys you will here altered cutoff
- this is as expected, every other key press cut filter
Also checked doing direct destination in seq 2 to cutoff, removing mod matrix source from seq 2
- turned filter cutoff down a bit on filter since each value in gated sequencer is positive only
- and also as expected, filter opens every other key press
If you cannot replicate thison REV2, I would do global reset and run calibration or something.
I have a desktop 16 REV2 with firmware 1.2.1 as shippedm using only main outs
- pressing global button fw version will show in display
Note! I notified checking using all 4 outputs from REV2 a couple of weeks ago, and something were different in how voices were allocated. And not setting to multi mode, just default.
- I am not checking with 4 outs now, just mains
