Want to emulate a trill in diva (or bazille)

[jumpercable]

Ive been experimenting trying to achieve a semi-realistic string/woodwind trill in a subtractive synth (Diva in this case) without much luck.

After trying out a load of different approaches (varying midi time, pitches, filters) I think the one thing that sticks out the most is the ADSR envelope. (not a criticism of Divas, just envelopes in general). It isnt smooth or natural enough on a repeated midi note, it still sticks out too much - trying to get the appropriate balance of a slow attack is very difficult, and legato isnt helping. Theres still a percussive click with sustain at maximum.

Is this just a situation with adsr? Is there a particular envelope shape that would help better? Or a particular routing to help balance this pluck on repeated? Its as if the notes dont 'blend' or 'gel' convincingly. Or maybe it requires alot of variation on the attack/decay stage.

Gliss doesnt help either, as 'scaling up' to the note is still too obvious.

Any ideas?

Have you tried a square LFO to pitch yet? Too unnatural sounding?

I'd use square LFO with some lag applied.

plus some volume and noise modulation

noise modulation

Totally. Essential for pretty much any acoustic-style sound, IMO. Real life doesn't do completely periodic waveforms, they are the voice of electricity.
