poly-recursion
Dynamically build a chain of DSP with poly~ objects inside poly~ objects. This software is a work in progress. Feel free to clone/fork and use it in any way. Also feel free to get in touch with suggestions/ideas/bugs and anything else.

About
This project is an exploration of the use of the poly~ object for dynamically loading a chain of DSP units. A branch (p_branch~) is replaced by a DSP effect (which is a branch by itself with some additional processing such as an overdrive). For every next effect it is loaded inside the previous effect. Eventually the chain is terminated by a leaf (the p_thru~) and the signal is routed back out through every branch up to the main patcher. A chain can be loaded with presets stored in a json file, but can also be instantiated with a list of symbols containing all the parameters for every effect.
Contains
-
main - The top level node of the tree, inputting the signal, setting the fx-chain, adjusting parameters
-
p_loader - Load the patcher in the poly~ object and apply the chosen preset or parameters.
-
p_thru~ - The leaf, a throughput of the input signal, returns the signal to the top level patcher
-
p_branch~ - An empty branch for poly~
-
p_reverb~ - A branch with the classic yafr2 reverb by Randy Jones
-
p_overdrive~ - A branch with an overdrive algorithm in gen~ ported from the DAFX book
-
p_lfo~ - A branch with an lfo effect
-
fx_settings.json - A dictionary filled with some presets
Overview
Usage
Open the project and start up the main.maxpat (should open automatically).
Presets
Provide a message with symbols for every effect you want to load. Append the message preset n for the preset you want to load in the poly~ object. () denote the start and end of a [message] object.
("drive preset 2")
Provide a longer message with multiple symbols to create a chain of DSP.
("drive preset 1" "reverb preset 2" "lfo preset 1")
Parameters
Provide all parameters in a message as one symbol to the [p_loader] object
drive
("drive <amount >1 > <wet/dry 0-1>")
reverb
("reverb <wet/dry 0-1> <size 0-1> <decay 0-1> <damping 0-1> <diffusion 0-1>")
lfo
("lfo <wet/dry 0-1> <frequency> <depth 0-1> <shape 0,1,2,3> <pulse width 0-1>")
