Correct. And only one per key press - not pairs, as you get with
midi->cv gates.

Hmm... that's so obvious I missed it. I could use my adsr to attenuate
the 'release' gate-derived sound from the filter.

Yes - I thought so too, initially, but the result definitely sounds
worse than sending the gate to the VCF.

Not sure how I'd do that.

As an aside, would I still have the same challenges (i.e. need to
derive a trigger) if I was using a low-pass gate to create the
wooden-block sound?
