I'm looking to live process a piano (for instance) and being able to change the attack time of each note. I'm not expecting to be able to do this without latency or delay. No idea where to start though, all the envelope shaping information I can find relates to synthesis and not real time mic input.
I'm a strictly vanilla user!

Thanks,

@Seán You could do something like this maybe......... like.zip

@whale-av Thanks for your reply - four months later I'm finally getting around to this.

I'm thinking of an effect like the Electro-Harmonix Attack Decay pedal. I used fiddle to detect note onset (maybe threshold is cheaper CPU-wise though?).

This patch can get me some of the way to making a piano swell etc. If anyone has anything to add, I'm all ears!

Thanks,
Seán
