supriya 0.1

一。获得supriya和supercallider

从GitHub：

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

从http://supercollider.github.io/获取SuperCollider。

运行测试以确保一切正常：

supriya$ tox

有关获取abjad的详细帮助，请参阅我们的安装说明， 设置它，并安装任何其他依赖项，如Graphviz。

2.发出一些噪音

启动python解释器并导入supriya:

>>> from supriya import *

启动超级准直器服务器：

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

创建和分配组：

>>> group = servertools.Group().allocate()

制作合成器定义并发送到服务器：

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

>>> with builder:
...     source = ugentools.SinOsc.ar(
...         frequency=builder['frequency'],
...         )
...     envelope = ugentools.EnvGen.kr(
...         done_action=synthdeftools.DoneAction.FREE_SYNTH,
...         envelope=synthdeftools.Envelope.asr(),
...         gate=builder['gate'],
...         )
...     source = source * builder['amplitude']
...     source = source * envelope
...     out = ugentools.Out.ar(
...         bus=(0, 1),
...         source=source,
...         )
...

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

与服务器同步：

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

使用先前定义的合成器定义创建合成器：

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

将其作为先前创建的组的子组分配到服务器上：

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

查询服务器的节点树：

>>> 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

将MIDI控制器绑定到Synth的控件：

>>> korg = miditools.NanoKontrol2()
>>> korg.open_port(0)
>>> source = korg.fader_1
>>> target = synth.controls['frequency']
>>> bind(source, target, range_=Range(110, 880), exponent=2.0)
Binding()

释放合成器：

>>> synth.release()

退出服务器：

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