Ah.. I didn't know that...
I thought the decay was reduced on accented notes, but I'd never have twigged the attack was also slowed at the same time. I assume it's only the filter attack that's altered, not the volume envelope.

So the resonance-boost on accented notes isn't actually from the filter circuit itself? Interesting...

Ah.. I seee. I hadn't analysed the sound in such detail, I must admit. And I don't have a 303 of my own to run tests on, sadly..
So is the filter env attack only altered on accented notes, or on all notes, as the resonance is increased?
