What is the A4 supposed to do when you send it a MIDI Program change?

Will it change sound, kit or pattern?

Pattern changes & recalls the associated kit.

Ok. Thanks!

Does the sequencer must be running? Or it works too when the sequencer is stopped?

I wish Program Change commands on the track-specific channels selected a sound from the sound pool.
