another way to maybe workaround unmuting all would be to add the ability to solo tracks.
TORAIZ - Massive De-Mute :)
During live sessions, it would be nice to de-mute all muted sounds in one go to have a genuine post-drop sequence !
Suggested feature: press <Shift> + <Mute> to break out all programmed sounds in that pattern.
I spoke too soon. If you're in mute mode and you hold shift, you can solo a track. hope that helps
So the desired de-mute function could be achieved by going into mute mode, holding shift and pressing two times a pad (solo and unsolo means de-muting all other tracks)
Thanks for the tips guys, I will fumble with that workaround to see if that is workable. Happy Beatcreating !
