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
2025-03-02 20:29:28 -05:00
tildearrow 49a8693dcb new chan osc, part 7
i am done
2025-03-02 16:14:49 -05:00
tildearrow 6265d2cd39 new chan osc, part 6
more adaptations

how can I get you out of my head... I want to go back to work!
