Single and multi trigger for envelopes?

[Halon]

Hi. Hope you all are doing well. I'm wondering how i would achieve single and multiple trigger modes for an envelope ?

Single would be playing a series of notes without retriggering, and multi > retrigger on every key/note.

Is there a specific envelope i should use in this case?

Cheers, and stay safe.

Interesting question and idea!

Just to be clear, do you want an option to start the envelope with the first key pressed and end it when the last key is released? And this envelope controls the polyphonic voices all together?

Multi is what you get in a conventional poly setup.
I believe the Single mode would need a mono envelope with mono to poly conversion on the output. In this way you would have to switch the poly paths between a regular poly envelope and this mono one. It should be possible with any envelope but you would have to provide the gate and env stage control signals for the mono one.

I agree with Spogg, it'll need a combination of blue and white streams. The gate signal for the envelope can be got easily by simply forcing the "number of notes" output of a "Midi Mono" primitive to boolean.

Hi Spogg, and yes, i want the envelope to start with the first key pressed and then end on key release. I can give you some examples of synthesizers that works this way, mind you these were old synths from the 70-80s, such as the Korg Mono/Poly and the Korg Delta. Also, with long release times, the 'release' stage was retriggered when pressing a new key, so i would assume this was what is called Paraphony perhaps? I always liked that behaviour to be honest. Thank you for suggesting the mono envelope and mono to poly. I should start experimenting.

Thank you trogluddite. How do you force the number of notes on 'Midi Mono' exactly? Does it work the way as 'Midi Poly' ?

That's probably best thought of the other way around. The "Midi Mono" has no maximum count of notes - it always keeps track of every note that's held down (the single output note always has "most recently played" priority). The equivalent for the "midi to poly" module would be to enable the "Hold Stolen" property - that way, it will "remember" every held note, even if there aren't enough voices to sound them all. It wouldn't do much harm if you didn't "hold stolen", but the release phase might not happen when you expect if there had been any voice-stealing before you released all of the keys.

I would associate multi-triggering (or "retriggering") and single-triggering ("legato") with mono synths, and "paraphony" with poly-synths that have shared mono envelopes. However, within FS, there wouldn't really be any technical difference except for the "Midi to Poly" having a different "Voices" setting.

Ok thanks again trogluddite.
