Hi, I've been experimenting with MIDI filters and with the damper pedal no problems so far. But I have trouble with SW1/SW2 MIDI Filters.
For example: My SW1 is configured as Octave UP. I'm on a Combi with 8 programs divided by zones and I only select Program2 to be affected by SW1, which I thought it would make just that program go up one octave and the rest of programs remain the same in their respective zones. Instead, all programs seem affected and all the zones "swap" one octave up, just as if I didn't make use of the MIDI filter at all.

Can somebody please explain me what am I doing wrong?

Thats an excellent question which I would also like to get around if there is a "work around" for it.

SW1 is NOT a midi signal. Assigning an octave change to it affects the keyboard itself, not the sound engine so it doesn't get filtered.
Another thing that can be assigned to SW1 is "SW1 CC#80" which can be used as AMS and that's what the filters are for.
One way I can think off is setting SW1 to SW1 CC#80 and in the program - assign OSC Pitch AMS to SW1 and +12. But that's not really a good idea, 'cause it gets the sound pitch-shifted, not transposed and that rarely sounds good
