Hi,
I’ve usually simply ignored the single layer patches in the VI collections.
Now, I’m starting to think that they can instead be very useful, when the dynamic range of a passage is limited, and you want the greater control on the cresc./dim. inside that limited range. It's what is offered in some Synchron libraries, where a Soft patch is included next to the full range one. The most notable advantage should be that there is no crossfade point.
Am I correct in seeing it this way?
