Supriya is a Python API for SuperCollider.
Supriya lets you:
-
Boot and communicate with SuperCollider's
scsynthsynthesis engine: servers in realtime. -
Compile SuperCollider SynthDefs natively in Python code
-
Explore nonrealtime composition with scores.
-
Build time-agnostic asyncio-aware applications with the context interface.
-
Schedule patterns and callbacks with tempo- and meter-aware clocks
Install from PyPI:
pip install supriya
Or from source:
git clone https://github.com/supriya-project/supriya.git
cd supriya
pip install -e .
Get SuperCollider from http://supercollider.github.io/.
Start your Python interpreter and import Supriya:
>>> import supriya
Boot the SuperCollider server:
>>> server = supriya.Server().boot()
Import some classes:
>>> from supriya import Envelope, synthdef
>>> from supriya.ugens import EnvGen, Out, SinOsc
Make a synthesizer definition:
>>> @synthdef()
... def simple_sine(frequency=440, amplitude=0.1, gate=1):
... sine = SinOsc.ar(frequency=frequency) * amplitude
... envelope = EnvGen.kr(envelope=Envelope.adsr(), gate=gate, done_action=2)
... Out.ar(bus=0, source=[sine * envelope] * 2)
...
Visualize the SynthDef (requires Graphviz):
>>> supriya.graph(simple_sine)
Allocate it on the server:
>>> _ = server.add_synthdefs(simple_sine)
Create and allocate a group:
>>> group = server.add_group()
Create some synthesizers with the previously defined synthesizer definition, and allocate them on the server as a child of the previously created group:
>>> for i in range(3):
... _ = group.add_synth(simple_sine, frequency=111 * (i + 1))
...
Query the server's node tree:
>>> print(server.query_tree())
NODE TREE 0 group
1 group
1000 group
1003 simple_sine
amplitude: 0.1, frequency: 333.0, gate: 1.0
1002 simple_sine
amplitude: 0.1, frequency: 222.0, gate: 1.0
1001 simple_sine
amplitude: 0.1, frequency: 111.0, gate: 1.0
Release the synths:
>>> for synth in group.children[:]:
... synth.free()
...
Quit the server:
>>> server.quit()
