General questions about a lot of modules

Filters:
Both should work like you describe. They are special filters and not meant to be clean or "normal". I assume there will be another filter module available down the road that is a bit less characterful.

ENV:
That's a typical behavior of many envelopes and there are special ones which will always finish the attack phase even on short triggers. In this module's case, you have to switch sustain on for attacks and send it gates. That's off the top of my head. I might have to check this again.

LFO:
You can only sync it, meaning it will reset the phase when triggered.

LOGIC:
Only inverts gates or triggers ... I think. I only used it for that and haven't tried it with CV. There are two CV inverters on the 2ATT/CV module (although they're not shown in the module graphic in the online store).



Edit: if you have certain wishes for modules, go ahead and post them in the pinned future module wish list thread

Yes, the attenuator knob then scales the inverted output, just like the normal one.
