chuck~ (for Pure Data)

a ChucK external for Pure Data
Martin Robinson
16 April 2007

chuck~ is a Pure Data external that makes it simple to use ChucK inside of your patches. Currently, chuck~ encapsulates a nearly-complete (see below) ChucK 1.2.0.8 environment. chuck~ passes PD signal and float data to and from the ChucK environment via the ChucK adc/dac units and special PD UGen. chuck~ is based on the original Max/MSP chuck~ by Brad Garton.

Usage

Here is a picture of an example (examples/test.pd in the distribution) usage of chuck~. I recommend that you download chuck~ and play with this patch yourself.

Errata

There is no good way to run multiple copies of chuck~. Currently all chuck~ objects share the same VM and it isn't even recommended to run more than one at a time.
On Windows, if the audio is enabled when a chuck~ object is destroyed and then a new one is created, PD crashes.
Script filenames are either relative from the current directory or located via absolute path. I'm not sure if it is possible to locate them relatively from the patch directory, but this would be the optimal behavior.
A few ChucK features are not supported in chuck~, including networking. Many, many more are untested (OSC and MIDI), but may very well work.
