One that I could do is build a delay-abstraction that receives the number of different matrices on[loadbang] and then dynamically patches inside itself the various needed [delwrite~]'s, [vd]'s and so on.

All the best, Jakob

Betreff: Re: [PD] one abstraction, different delay lines?

Hello again!
Yep, maybe I should explain what I want to do :-P
I am building a sequencer instrument that mainly consists of a matrix of push buttons.
When you press a button in a column and the sequencer arrives there, then a certain midi note is played through an instrument and into [dac~].

The user can go through several matrices, allowing him to play e.g. a melody on matrix 1 and another melody on matrix 2.
Now my next steps are:
- implementing the possibility for an instrument change, so that the user is able to specify an instrument he wants his midi note to go to for his different matrices
- implementing the possibility for a delay effect per matrix: Say the user is on matrix 1 and plays a melody there. Now he chooses to activate a delay effect for this matrix. For this I could take the delay-effect-abstraction that I mentioned.
The user plays a little bit with the "feedback", "dry/wet" and "delay timing" settings. The user hears the delay effect.

Now we are approaching what I want to achieve: The user is happy with his melody and his delay-settings on matrix 1. Now the user changes to the second matrix because he wants to play another melody on top. Internally, he does this by incrementing a counter to value 2. The second melody should NOT be affected by the delay settings that the user applied for the melody on matrix 1. This means, that each matrix needs to have its own delay effect or its own delay-effect-settings. What I could certainly do, is to copy and paste my delay-effect-abstraction to have two independent delay-effects for each matrix/each melody. But I would like to avoid to copy-and-paste because the number of matrices should be easily changeable. I want to keep the patch as generic as possible. At the moment I have a number for specifying the number of matrices. This number is [loadbanged] and the patch does the rest on startup. I would like to keep this. But for this, my delay abstraction has to be able
- to listen for a matrix-change (receiving the corresponding counter value)
- to save the settings for each matrix and show them when a matrix change is noticed
- to write into different delay lines for having the audio effect affect only the audio of a certain matrix.

I hope that it is more clear now:-)

At the moment, I have absolutely no idea how i could achieve this:-(

All the best, Jakob

so that it will be able to write into/create different delay lines "on the fly"?It's currently not possible to dynamically changing the source delay line ("write into") for objects like [delread~] or [vd~], but it would be good feature request! I'm not sure why you would want to dynamically "create" a delay line, though.

Dear pders:)
Recently I have built my first abstraction for a delay-effect.
Now I have a question. Is it possible to extend this abstraction in a way,
so that it will be able to write into/create different delay lines "on the fly"?

Thanks, Jakob
