adsr - Hold a note in Live Coding Environement?

[micoloth]

Hello

First of all- What an amazing project!

I like it very much, I want to learn it and possibly even contribute to it in the future.

As first issue.. I have not been able to use the ADSR node. (also it's not documented, and I haven't found any example).

Could you provide an example of a code that produces sound?

(Eg this one doesn't
~env: imp 1.0 >> adsr 1 10 10 1
o: sin 200 >> mul ~env >> mul 50
)

Thank you very much!

the adsr node is designed for glicol-js mainly and we usually don't use it for live coding.

adsr example can be found here: https://glicol.js.org/adsr.html

in live coding, envperc is enough for most cases: https://glicol.org/tour#envelope

Hi chaosprint 👋

Thank you for your answer!

Would you be interested if I opened a PR to expose the adsr to the Live Coding Environement as well?

(I would add all the pieces, such as docs, parsing rules, etc)

I would gladly do it, also it would be good for me to learn how Glicol's internals work.

Or are you rather not considering PRs right now?

In any case, thank you for your work

Ah..
Followup

I have seen your example https://glicol.js.org/adsr.html
I understand now how adsr works with ConstSig:

• Turn on sig: trigger Attack
• Turn off sig: trigger Release

I wonder, Does this mean that there is no way in Live Coding Environement to hold a note for a given interval?
Also seq only produces impulses..

Again, are you thinking about/ would you be interested in adding support for this use case in some form?

There is a point node that may be able to do this with seq. But as you said, I need to improve the documentation. The new website is already under development.

Ah Cool!

I didn't know about the Points node.

I have figured out how it works:

~note: [0.01 => 0.25 0.02 => 0.] !
means: after 0.01 bar raise to 0.25 volume. And at 0.02 bar go down to 0 again. Right?

The only thing I'm missing now is how to use it- what are the input and outputs.

I've tried modulating some Quarter or 16th notes like this:

~note: [0. => 1.  1/16 => 0.  2/4 => 0.  9/16 => 0.] ! 
~ampenvsynth: ~note >> adsr 0.01 0.3 1. 0.01
melody_out: sin 220 >> mul ~ampenvsynth

beat: seq 33 _ 33 _ >> trisynth 0.01 0.1  >> mul 50

But it doesn't work exactly as I expected, eg the duration appears to always be one half beat.

Am I using it wrong ?
