Multitrack and arpeggiator

Hi all!

I try to do something but I have a bit of trouble with the arp setting.

Let me explain : I want to set up different tracks with different sounds on a kit to be able to play the whole kit along right on a midi keyboard. I use unison setting and “use track sound” it work nice except I can’t use arpeggiator on a single track only, or 2 different arpeggiator on 2 different tracks.

Is there a way to do it or the architecture of the A4/AK don’t allows it?
