Thanks for the response, I didn't found it googling so I tough that would be a uncommon question.
A cool advantage for this use case would be allowance of "continuous strings background" at the pads, on Chord type with any tone (that for me, as it is currently there is no advantage (for current scenary) with rhythms - bass, drums & others playing).
Well, but still I want to make it, so I would need to create a rhythm without any instrument or track, with only my strings tone and put it on play every time that I want to use it on accomp/pads?
