Change Logs

* Wed Oct 31 2018 Todd R <>
- Update to version 0.9.1
  * On Windows, use 'directsound' as the default audio host (much more
    reliable than 'wasapi').
  * Fixed phase shifting between the frequency bands of FourBand and MultiBand.
  * Added a new object: MultiBand, frequency splitter using Linkwitz-Riley
    crossover filters.
  * Fixed Compress output level when input's rms is above unity.
  * Added the ability to remove a project from the project tree.
  * Added getPrecision() function. Removed print statement when importing pyo.
    User should use getVersion() and getPrecision() functions if needed.

  * Fixed Server window's Interpreter field scrolling history on MacOS.
* Wed May 16 2018

    interpolated value for a floating-point position in the matrix.

    greatly help finding the device indexes (especially on Windows) to give to
    the server in order to use to desired audio host.
  * Added a new winhost argument to the Server's initialization. On Windows, it
    defaults to WASAPI.
  * Check the jack api version before compiling to ensure existing functions are
    used (jack_port_set_name/jack_port_rename).
  * Added two examples in 07-effects, and

    according to the event's timestamp.

  - New objects:
  * LogiMap, random generator based on the logistic map.
  - New functionalities:
  * Added a method (sysexout()) to send sysex messages to the Server object.
  * Added PyoTableObject.getBuffer() method. The PyoTableObject now support
    the buffer protocol (see PEP 3118), which allow a table to share its data
    memory with any object that support the buffer protocol (ex. numpy array).
  * Added Server.setCallback() method to allow the user to define a custom
    process function. This function will be called once per buffer size, just
    before the computation of the audio objects tree.
  * Added Server.getCurrentTime() and Server.getCurrentAmp() methods.
  * Improve Looper object: Added a time stream, which gives the current
    normalized position. Added loopnow() method, which allows to start a new
    loop immediately with crossfade. Added appendFadeTime() and fadeInSeconds()
    methods to give a more flexible control of the behavior of the object.
  * Added an 'inverse' argument to PVGate object. When set to True, the
    damping factor is applied to bins with an amplitude above the threshold.
  * Added a `callback` argument to PyoObject.set() method. The given callback
    will be executed at the end of the ramp.
  * Added ctrl() method (and some missing setter) to midi objects.
  * TableWrite object now takes into account the feedback argument of NewTable
    object and interpolates to fill in gaps if its writing pointer moves faster
    than the sampling rate.
  * Added a reset() method to various delay line-based objects (AllpassWG,
    Chorus, Freeverb, Harmonizer, STRev, WGVerb, Waveguide).
  * All objects can be used as iterator (will iterate over its internal sterams).
  * SigTo ramp time now can be controlled at audio rate.
  * Iter object now sends a trigger when it reaches the last value.
  * Iter object now accepts PyoObjects in its list of values.

  * Replaced all printf calls with PySys_WriteStdout. This allow to redirect
    messages from pyo to a string or a file, instead of the stdout.
  - Documentation:
  * Added new examples, 05-envelopes/ and 06-filters/.
