tildearrow b3b50bdb66 ESFM: optimize osc buf 2025-03-03 01:45:42 -05:00
tildearrow 6d55c8088c GA20: yaaaay I fixed chan osc 2025-03-02 20:41:34 -05:00
tildearrow 8f54445625 GA20: acquireDirect optimizations, part 1
buggy, slow and glitchy
output is good but chan osc is now broken

from 1.5 to 0.4 seconds

tildearrow 4ca7033dec Revert "prepare acquireDirect API" - stupid crap
the most POINTLESS plan of all time... acquireDirect.
why? because you gotta fill in the oscBufs anyway, which will take
precious CPU time, so you can't just pass the blip_bufs to dispatch
and hope it'll help by not processing when nothing's happening.

"so disable it when the per-chan osc is up!" NO! we need this for
volume calculation....

"how about rewrite per-chan osc logic?" you know what? I don't have
either the time or the will for that.
now back to Something Else......

This reverts commit 08177d839a.
