csoundengine ============ |sh-month| .. |sh-month| image:: https://static.pepy.tech/badge/csoundengine/month This package implements an intuitive interface to run and control a csound process Documentation ------------- https://csoundengine.readthedocs.io/en/latest/index.html ----- Introduction ------------ The core of this package is the ``Engine`` class, which wraps a csound process and allows transparent control over all parameters, while providing sane defaults. It uses the csound API to communicate with a running csound instance. All audio processing is run in a separate performance thread. .. code-block:: python from csoundengine import * # create an Engine with default options for the platform. engine = Engine() # Define an instrument engine.compile(r''' instr synth ; pfields of the instrument kmidinote = p4 kamp = p5 kcutoff = p6 kdetune = p7 kfreq = mtof:k(kmidinote) ; A filtered sawtooth asig = vco2:a(kamp*0.7, kfreq) asig += vco2:a(kamp*0.7, kfreq + kdetune) asig = moogladder2(asig, kcutoff, 0.9) ; Attack / Release aenv = linsegr:a(0, 0.01, 1, 0.2, 0) asig *= aenv outs asig, asig endin ''') # Start a synth with indefinite duration. This returns the eventid (p1) # of the running instrument, which can be used to further control it event = engine.sched("synth", args=[48, 0.2, 3000, 4]) # Change midinote. setp means: set p-field. This sets p4 (kmidinote) to 50 engine.setp(event, 4, 50) # Modify cutoff engine.setp(event, 6, 1000, delay=4) # Create a ui for this event: engine.eventui(event, p4=(0, 127), p5=(0, 1), kcutoff=(100, 5000)) .. figure:: https://raw.githubusercontent.com/gesellkammer/csoundengine/master/docs/assets/eventui2.png Session - high level interface ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each engine can have an associated ``Session``. A Session provides a higher level interface, allowing to: * Define instrument templates (an ``Instr``), which can be instantiated at any order of evaluation, allowing to implement processing chains of any complexity * An ``Instr`` can have named parameters which can be used to control the event. * A ``Session`` provides a series of built-in ``Instr``'s to perform some common tasks, like playing samples from memory or from disk, perform audio analysis, etc. .. figure:: https://raw.githubusercontent.com/gesellkammer/csoundengine/master/docs/assets/synthui.png .. code-block:: python from csoundengine import * # Create an Engine and a corresponding Session using default options session = Engine().session() # create a master audio bus masterbus = session.assignBus() # define instruments session.defInstr("synth", r''' |ibus, kmidi=60, kamp=0.1, ktransp=0, ifade=0.5| ; a simple sawtooth asig vco2 kamp, mtof:k(kmidi+ktransp) asig *= linsegr:a(0, ifade, 1, ifade, 0) ; output is routed to a bus busout(ibus, asig) ''') session.defInstr("filter", r''' |ibus, imasterbus, kcutoff=1000, kresonance=0.9| asig = busin(ibus) asig = moogladder2(asig, kcutoff, kresonance) busmix(imasterbus, asig) ''') session.defInstr("master", r''' imasterbus = p4 asig = busin(imasterbus) asig compress2 asig, asig, -120, -40, -12, 3, 0.1, 0.01, 0.05 outch 1, asig ''') # Start a master instance at the end of the evaluation chain master = session.sched("master", imasterbus=masterbus, priority=10) # Launch some notes for i, midinote in enumerate(range(60, 72, 2)): # for each synth, we create a bus to plug it to an effect, in this case a filter # The bus will be collected once all clients are finished bus = session.assignBus() # start time for synth and effect start = i * 1 # Schedule a synth synth = session.sched("synth", delay=start, dur=5, kmidi=midinote, ibus=bus) # Automate pitch transposition so that it descends 2 semitones over the # duration of the event synth.automatep('ktransp', [0, 0, dur, -2], delay=start) # Schedule the filter for this synth, with a priority higher than the # synth, so that it is evaluated later in the chain filt = session.sched("filter", delay=start, dur=synth.dur, priority=synth.priority+1, kcutoff=2000, kresonance=0.92, ibus=bus, imasterbus=masterbus) # Automate the cutoff freq. of the filter filt.automatep('kcutoff', [0, 2000, dur*0.8, 500, dur, 6000], delay=start) ----- Installation ------------ https://csoundengine.readthedocs.io/en/latest/Installation.html Dependencies ~~~~~~~~~~~~ * python >= 3.9 * csound 6 >= 6.16 (https://github.com/csound/csound/releases). .. code-block:: bash pip install csoundengine **csoundengine** also needs many csound plugins (https://github.com/csound-plugins/csound-plugins/releases), but these are installed automatically if needed. Documentation ------------- https://csoundengine.readthedocs.io ---------------- Usage in other projects ----------------------- * **csoundengine** is used as the audio engine in `maelzel <https://github.com/gesellkammer/maelzel>`_
