Gate lengths in ticks

[mgd]

If ticks are not possible, please consider changing the arbitrary values so they cover a broader range: 1ms, 5ms, 20ms, 40ms, 60ms, 80ms, etc.. I dont see why so much detail is needed between 5-65ms

That seems a valid point to me. In that sense I would propose something like:
1ms, 5ms, 10ms, 20ms, 50ms, 100ms, 200ms, 500ms, etc. (may be insert 2ms).

But for envelopes I'd rather see ticks as well. Currently I'm adjusting attack and release depending on BPM.
