Don't render the empty channels in per channels mode.

[gtr3qq]

I'm sorry.... if it's such a first world problem....
The VERA module contains 16PSG channels, and it's usually not fully utilized due to size limitations of the output ZSM file not fit in RAM.
Thus channels are often empty. And can not be turned off.
But rendering them takes a good chunk of time...
I know, it's just a few second, be better if I go grab a tea. than fixing it........

(sigh...)Man....................... Sorry to trouble you then....
Although, one could say if one was to pull all the chips, and ended up with many more unused ones...............
Also, there's a possible PSG Volume behaviour change with VERA module coming up that will mess with the Mix level....... So heads up......
edit: the Volume update is merged to VERA hardware, no action needed on furnace end.
Thanks your time and amazing tracker!

Turn off the channels in the channels tab don't help either.

I think that one can check in all patterns for unused channels, then, you simply don't render them. But, I think it would be faster you just let it be.
