and this -
decided to add a shape param to envelopes for percussion as i've noticed many of the sounds i like have the ogee/turnip kinda taper to them.
default contours are linear, ^2, ^3, ^4 (curve param) horizontally. originally i'd intended to have the shape param adjust the contours in one direction (towards the upper row) giving that fireball shape i want. this morning i noticed the funky contours are very similar to a very famous drum machine sound.. and probably have good application as they immediately damp the attack and have a ~body swell.
so we're now up to two additional parameters for an envelope section.. have i daunted you with my excessive parameterisation yet?
after making the diagram, i thought, okay, well, let's go in the other direction my envelopes go in, and it looks like this:
itfp, everything below the center is mostly junk, perhaps the occasional emulative application for stuff with odd resonances. the stuff on the top line is visually appealing to me.. but can pretty much be done using the note length and release time when sequencing. i'm thinking i could leave this axis out and no one would miss it. leaving it out will remove the additional complexity of resetting this param to zero.
for those who are interested, the s-curve is noted in my dsp pdf x*x*(3-2x) and can be done like this in synthedit or other modular systems if you don't code.
the difference in curvature is less subtle to the ear (eg. those ^4 tails look flat but are certainly audible).
