Help With AD envelope

Developers Pure Data
#1

I am trying to build a simple Attack Decay envelope and get it to work on the mod.

The decay part is working as expected, however when I open the Attack, no sound comes through anymore.

The patch works in PD on a desktop when I use slider/button elements and a testtone

Why are you using [pack] when you only care about one of the numbers? Just use a plain [f] instead?

#3

it’s an adaption of miller pucketts examples/tutorials:

switching it to f doesn’t work.

#4

Sorry but I don’t see it. Maybe start by doing something much simpler.

By the way the [delay $2] is never going to work. This $2 is normally used when initializing an abstraction, but your patch is not being initialized with any such number.

I inserted a bang after the trig and now it works perfectly. It seems the mod/heacy trigger param is not working the same way as the regular trigger.

This is because it’s not supposed to. This “type” is to make the plugin-side behave a certain way. Nowhere is it said that it will output a bang event. It outputs a number, either 0 or 1.

As I said I don’t see how your patch relates to Millers ADSR tutorial.
And as you can clearly see he uses a [sel 0] on the “trigger” input, which will exactly output a bang when the number 0 is entered. (in this case I’d do a [sel 1] so you have a “rising edge” response)

Maybe try to actually follow this tutorial instead of randomly making changes that don’t make any sense?

And as I also said your use of $2 will not do anything (or rather it will initialize with the number 0).
