### 4/5 — AuV3

*2026-08-13, version 1.4.6*

I’ve been playing with this synth for about 6 months now on and off, the more I do play with it, I really enjoy the functionality and tones but I’m also stumped with one thing. Can AuV3 support and functionality be added to the list of features the app incorporates? Thank you, I think that’s the only real thing missing from this instrument.

### 4/5 — Way better than first glance

*2026-07-21, version 1.4.5*

Yea this is real good at getting good little starting points or a huge sick riff. I think it’s the per step edits that really make this app for me. I can’t get tired of using some limited percussion sound but tweaking it each step to make a dope pattern.
