| br>Here are some screen shots of the effect of plugging an ADSR Envelope Generator into a Velocitizer eurorack module, at various levels of velocity (0V, 2.5V, 5V roughly.)
I think it explains the operation better than words: not only do different velocities alter the level of the EG, it also changes the curve and the sustain ratio different for each velocity.
The rationale for this behaviour came from some measurements of the dynamics of violin detached note playing, where fff, m, and p playing all had basically the same attack, decay and release times, but the peak and sustain levels varied by different ratios and the attack/decay/release curves became fatter. So it is like pianissimo follows the ADSR softer, the moderato playing is peak-limited, and the forte playing is loud but with a fatter peak.
(You would need an ADSR with VC Peak, VC Sustain and VC curve to get the same effect, more complex. I wanted something too convenient not to use, so that it would be "of course this patch is velocity sensitive" rather than "I already have a rats nest and no time to patch more, what a shame, velocity would have helped.")
Technical: These traces were actual done at audio rates, with a VCO driving a CEMvelope, going into an Elby kit Velocitizer EG input, then to the CRO. You can use the Velocitizer at audio rates as a mild VC waveshaper eg as a chorus effect, or even as a kind of non-linear 2 or 4Q multiplier for a kind AM or ring mod effect, apart from the marquee use of making velocity-sensitive EGs.
