Got it. Thanks!
+1 on Slew/Lag/etc. with the addition of having lag curves (log,exp,lin) as it would allow replication of traditional glide functions, but also allowing us to get loads of ‘curves’ from the existing modulation sources.
I’d also like other static scaling functions, and thinking of a similar list to edit curves in a good-quality DAW - sine or ‘S-Curve’ (as in the one that looks like a saturation curve), lin, log, and variants.
Variable ‘bit’ stepping functions could be nice as well, allowing otherwise subtle mod to jump out a bit. In other words, could choose the ‘chunkiness’ of steps from very big to nearly smooth.
Half and full-wave rect would be handy in some cases.
Perhaps something like ‘invert on end of cycle’? Could get bipolar modulation out of the envelopes…
I could think of others, but it gets pretty esoteric (i.e. derivative / integrator )
