ADSR Mystery trigger

[payaDSP]

Hello to all;
I am new to DSP, and I start by the beginning
I play a little with examples.

My question is :
How is triggered ADSR standard module ? (I mean without connecting trigger)

I try to add a simple LED indicator which flash when ADSR starts.
No way (for me)

The workaround is to use a "MIDI LED" found on the forum (built from SPLIT MIDI).
It works, but an indicator on ADSR module itself should be more educative

anyone could help me ?
Thanks to all

(sorry for my wollapuck English)

After multiples tries:
i can see when ADSR send signal, reading it (or with cyto indicator)
i cannot transform this reading in simple flashing led

i manage to transform TRIGGER in BOOL but even with ticker to 100 there is no change at the end (reading or LED indicator). This is partially working, on the scope i can see sometimes TRUE signal, but not at every note.

Hey payaDSP, Welcome

The reason why it seems to not be working is because the trigger output gives a true bool for only the first sample. So it is true for an incredibility short period of time way too short to be picked up by a ticker 100.
The scope picks it up because it has a large window size (4096 samples) so if the bool is sent during the windows time frame it will show up.

What you need to do it use the "Gate" output of the midi to poly, this will give a bool that stays true while the note is pressed.

Hello;

thank for your answer, this is what i suspected (i put tick100 instead of tick25 in the original scheme, but it misses a lot of key pressed)
anyway this is only the second part of my beginner's questions.

I dont understand how standard ADSR is triggered (no visible link with MIDI).
Could you explain this ?

Thanks again

inside the adsr module you can find the 'env' primitive (it is inside the gate module)
the envelope primitive starts the envelope automatically always when a polysignal (note) is generated, which happens in the the midi to poly module

[payaDSP]

thanks, I found it.
so it is a standard built-in module, but what i miss is how this module (which is connected to GATE ) can intercept GATE with this input left unconnected ?
this is only frustrating question

on the other hand is there a way to translate to POLYBOOLEAN to BOOLEAN ?

Thanks to all
i manage to workaround
MIDI > ADSR > envelope as 0,0,1,0 + gain at 0.9 (experimental) >poly to mono > mono to float > bool
