SuperCollider library for Python

This project is a port of core features of SuperCollider's language to Python 3. It is intended to be the same library in a different language and to keep sclang elegance in a pythonic way (if possible).

The main reason for this port is Python's capacity of interaction with other libraries applicable to composition, sonic-art and research. My wish is for this project to be useful for the SuperCollider community.

Note that this project is still under development and there are missing parts, bugs you are welcome to report, and documentation is under construction. The best way to learn about SuperCollider is going to the source.

Example

The idea is that you can write the same in Python as in sclang, with the same logic regarding multichannel expansion, arguments conversion to Control ugens, etc., it should be the same result. For example:

from sc3.all import *

s.boot()

@synthdef
def sine(freq=440, amp=0.1, gate=1):
    sig = SinOsc(freq) * amp
    env = EnvGen(Env.adsr(), gate, done_action=2)
    Out(0, (sig * env).dup())

sine.dump_ugens()

Wait for boot...

n = Synth('sine')
n.set('amp', 0.05)
n.set('freq', 550)
s.dump_tree(True)
n.release()
# s.free_nodes()  # If something went wrong free all nodes.
s.quit()  # Stop server at the end of interactive session or just quit ipython.

Install

From PyPI (usually outdated by now):

pip3 install sc3

From source in develop mode (recommended for the moment):

python3 setup.py develop --user

License

The sc3 library is free software available under Version 3 of the GNU General Public License. See COPYING for details.

NB: The sc3 library is a Python translation of the SuperCollider's library and inherits its same license and community guidelines.

  • FM7 synth

    FM7 synth

    Hi! Is it possible to add FM7 synth? I am especially interested in its arAlgo function. Thanks.

    Also, I tried writing something like:

    from sc3.synth import ugen as ugn
    
    class FM7(ugn.MultiOutUGen):
        @classmethod
        def ar(cls, ctlMatrix, modMatrix):
            return cls._multi_new("audio", ctlMatrix, modMatrix)
    
        def _init_ugen(self, *inputs):
            self._inputs = inputs
            return self._init_outputs(6, self.rate)
    

    but it will return "ChannelList([ChannelList([ChannelList([..." which I don't know how to convert into sound.

  • Add missing bin_dir() method to DarwinPlatform class.

    Add missing bin_dir() method to DarwinPlatform class.

    I'm not sure if this is the correct way to add this method, but it worked on my Mac.

    I had to add this because when it tried to import everything (Sphinx does this when building docs), it tried to call bin_dir() and raised a NotImplementedError.

    Updates on the fly, for live-coding

    Hi! Say I want something like Pbindef with dynamic updating, for live coding, like here in Eli Fieldsteel video: https://youtu.be/8Is3hJvzjvs?t=1217 How do I do this? How do I use quant (so that new updates/changes will land on a beat, not in the middle of a pattern)? How do I update speed of TempoClock?

  • Scsynth not found.

    Scsynth not found.

    Hello, First this project look really interesting. Something you dream at night when you begin in Python and Supercollider... And you did it! i love the transcription between the two laguage.

    I wanted to test and get this error (with your example script) : ERROR:sc3.synth.server:localhost failed to boot, program scsynth not found

    I'm on mac OS Catalina. Python3.7.4 SuperCollider 3.11.2 My regular SuperCollider app is in /Applications/SuperCollider. I copied this app to this path to : /Users/macbook/Applications/SuperCollider but same result...

    got sc3 from source code in develop mode (everything goes fine).

    For info i can use without problem an other SuperCollider / Pyhton project => supercollider and start SC server within VS-Code. So i'am wondering why it doesn't find my Scsynth program?

    Thank you very much. I hope to test it soon ! Michaël Filler.

    syntax for patterns, loading buffers etc

    Hi,

    I was wondering if you wouldn't mind clarifying what the syntax would be for accessing the patterns functionality, and for loading buffers. Also is JITLib (Ndef, Pdef, Tdef etc) included in this wrapper?

    Thanks,

    Mark

  • Use Sphinx to generate documentation.

    Use Sphinx to generate documentation.

    Includes an index.rst based on README.md, and sets autodoc and other Sphinx extensions for autogenerating module documentation from docstrings.

    Personally, I also recommend configuring readthedocs for free hosting and automatic generation on git pushes :)

    Missing patterns from RandomDistPatterns.sc

    Discussed in https://github.com/smrg-lm/sc3/discussions/14

    Originally posted by d3vp July 31, 2022 So far I have added the following things I found missing in sc3:

    • method: Env.delay
    • class Pgauss(ValuePattern)

    Is there any alternative to delay?

    Problem using list of freq in synthdef & Pbind

    Hi,

    First of all, thank you for the great library. I am trying to implement this example using sc3.

    from sc3.all import *
    
    @synthdef
    def dtmf(freq=(770, 1633), out=0, amp=0.2, gate=1):
        son = SinOsc.ar(freq, 0).sum() * amp
        env = EnvGen.ar(Env.asr(0.001, 1, 0.001), gate, done_action=2)
        Out.ar(out, Pan2.ar(son * env * amp))
    
    # this works:
    Pbind({'instrument': 'dtmf',
            'dur': Pwhite(0.2, 0.5),
            'sustain': 0.15,
            'amp': 0.3,
            'freq': Prand([697, 1209, 770, 1209], 13)
    }).play();
    
    # but this does not work:
    Pbind({'instrument': 'dtmf',
            'dur': Pwhite(0.2, 0.5),
            'sustain': 0.15,
            'amp': 0.3,
            'freq': Prand([[697, 1209],[770, 1209], [852, 1209], [697, 1336]], 13)
    }).play();
    

    But getting following error:

    ERROR:sc3.base.clock:EventStreamPlayer(EventStreamPlayer._stream_player_func.<locals>.esp_func) scheduled on SystemClock
    Traceback (most recent call last):
      File "/Supercollider/sc3/sc3/base/clock.py", line 237, in _run

        return self.next((self, clock))
      File "/Supercollider/sc3/sc3/base/stream.py", line 491, in next
        self._last_value = next(self._iterator)

        return self('freq') * self('harmonic') + self('detune')
    TypeError: can't multiply sequence by non-int of type 'float'
    

    Not sure if I am doing something wrong or it is a bug or missing feature.
