Muting / Soloing parts

[neomad]

Hello everybody, a quick question, please:

I am a Kronos owner, but I do not want to move 2/3 times a week going to studio. I keep the Kronos only for live gigs.

I am considering to buy a smaller and lighter keyboard for that purpose (x50, kross or even M50).

Question is:

Can I mute / solo parts on the fly ? (example with knobs or buttons?). I some songs I'm using about 4/5 parts and I would like to kill the sound in some parts (example, only uses swell choirs pad for 'verse', the come back only to piano sound).

Can this be done with 4 knobs or joystick or SW1/2?

I've downloaded manuals of X50 and Kross yesterday, but could not find the way to asign mute functions to controls within Combi mode.

Thanks in advance for your valuable help
regards
Matt
