supriya 0.1

Supriya is a Python interface to SuperCollider.

Supriya lets you:

• boot and communicate with SuperCollider's scsynth synthesis server
• construct and compile SynthDef unit generator graphs in native Python code
• build and control graphs of synthesizers and synthesizer groups
• object-model scysnth OSC communications explicitly via Request and Response classes
• compile non-realtime synthesis scores via Supriya's nonrealtime.Session class

Note

This project is still under heavy development, is not yet stable, and is not yet intended for deployment in the field.

Supriya is compatible with Python 3.6+ only.

Quickstart

1. Get Supriya and SuperCollider

Get Supriya from GitHub:

~$ git clone https://github.com/josiah-wolf-oberholtzer/supriya.git
~$ cd supriya
supriya$ pip install -e .

Get SuperCollider from http://supercollider.github.io/.

Run the tests to make sure everything's OK:

supriya$ pytest

Consult our installation instructions for detailed help on getting Supriya, setting it up, and installing any additional dependencies like Graphviz.

2. Make some noise

Start your Python interpreter and import Supriya:

>>> import supriya

Boot the SuperCollider server:

>>> server = supriya.Server.default()
>>> server.boot()
<Server: udp://127.0.0.1:57751, 8i8o>

Create and allocate a group:

>>> group = supriya.realtime.Group().allocate()

Make a synthesizer definition and send it to the server:

>>> builder = supriya.synthdefs.SynthDefBuilder(
...     amplitude=1.0,
...     frequency=440.0,
...     gate=1.0,
...     )

>>> with builder:
...     source = supriya.ugens.SinOsc.ar(
...         frequency=builder['frequency'],
...         )
...     envelope = supriya.ugens.EnvGen.kr(
...         done_action=supriya.DoneAction.FREE_SYNTH,
...         envelope=supriya.synthdefs.Envelope.asr(),
...         gate=builder['gate'],
...         )
...     source = source * builder['amplitude']
...     source = source * envelope
...     out = supriya.ugens.Out.ar(
...         bus=0,
...         source=source,
...         )
...

>>> synthdef = builder.build().allocate()

Synchronize with the server:

>>> server.sync()
<Server: udp://127.0.0.1:57751, 8i8o>

Create a synthesizer with the previously defined synthesizer definition:

>>> synth = supriya.Synth(synthdef)
>>> synth
<Synth: ???>

Allocate it on the server as a child of the previously created group:

>>> group.append(synth)
>>> synth
<Synth: 1001>

Query the server's node tree:

>>> response = server.query_remote_nodes(include_controls=True)
>>> print(response)
NODE TREE 0 group
    1 group
        1000 group
            1001 f1c3ea5063065be20688f82b415c1108
                amplitude: 0.0, frequency: 440.0

Release the synth:

>>> synth.release()

Quit the server:

>>> server.quit()
<Server: offline>
