At the moment, tempo control does not allow you to decrease the sample rate below -50%. This is very upsetting. Of course, you can use the play speed on top, BUT this causes terrible loss of quality.
All I have to do is patch it myself. Fortunately, I can do it, but not everyone can do it. This needs to be done out of the box instantly.
DSP: Tempo Control:
1 Change sample rate minimal value to -80%;
2 Add Profiles;
Hotkeys:
1. "Player: Sample rate Increase (+1%)",
2. "Player: Sample rate Decrease (-1%)",
// We strongly ask you to make exactly 1%. As far as I know, holding for continually increasing - works. There shouldn't be a problem here.
