kandi X-RAY | pyfluidsynth Summary

pyfluidsynth is a Python library typically used in Audio, Audio Utils applications. pyfluidsynth has no vulnerabilities, it has build file available, it has a Weak Copyleft License and it has low support. However pyfluidsynth has 1 bugs. You can install using 'pip install pyfluidsynth' or download it from GitHub, PyPI.

This module contains python bindings for FluidSynth. FluidSynth is a software synthesizer for generating music. It works like a MIDI synthesizer. You load patches, set parameters, then send NOTEON and NOTEOFF events to play notes. Instruments are defined in SoundFonts, generally files with the extension SF2. FluidSynth can either be used to play audio itself, or you can call a function that returns chunks of audio data and output the data to the soundcard yourself. FluidSynth works on all major platforms, so pyFluidSynth should also.

QUESTION

Python threading only working when called from another module

Asked 2019-Aug-23 at 21:10

I am working on an app that accepts MIDI keyboard input (using Mido) from within a Kivy application. The goal is to have one thread that constantly polls the MIDI input and routes events to pyfluidsynth, while a conventional Kivy app is running in parallel. I need some sort of parallel process, or else the Kivy UI freezes for as long as the midi poll while loop is running.

After much fiddling, I got it to work, but I'm a bit concerned about the code. I tried starting the threads under [if name == "main"], but was only ever able to run one process, followed by the other.

Then by accident I was able to get the desired effect by leaving in the last 2 lines of code in mido_midi.py, which were originally just for testing. Now, when I run main.py, I get the app plus the keyboard input. Other than some ugly behaviour when I close the app, things appear to be working the way I wanted.

My concern is that I can't seem to get the threading to work by calling everything from main. Since things are working, and I don't understand why, and it looks wrong to me. I thought I'd throw it to smarter people for insight.

Am I doing it right? If not, what do I need to change? Thanks.

Your code is starting the KeyboardInput thread when you do the from mido_midi import start_synth, KeyboardInput and the "testing" lines are executed at that time. The if __name__ == "__main__": is a construct designed to prevent exactly that from happening when a file containing that construct is imported. Also, note that you have two different instance of KeyboardInput. Not sure if that is your intention.

You should be able to start the thread inside your if __name__ == "__main__": block by just adding the same two lines inside that block:

QUESTION

Ignoring exception in import and proceeding with rest of module?

Asked 2019-Jan-12 at 03:38

The python package that I am developing has a dependency (pyfluidsynth) that breaks on my system by throwing an AttributeError on import. Pyfluidsynth is a wrapper around the C library "fluidsynth", and it the reason that it breaks is that it is trying to wrap a couple C functions that don't exist in the library, at least for the version of fluidsynth on my system.

These are the offending lines of code:

You can fork pyfluidsynth and depend on that instead until it gets fixed. This is probably a better option than monkeypatching. Pip can install packages hosted on GitHub if you don't want to put it up on PyPI. Use a git+https URL to the repository (and branch, if necessary) instead of just the package name.

That said, you can probably use unittest.mock.patch to replace ctypes.CFUNCTYPE with a version that returns a wrapped function prototype that checks for fluid_synth_set_reverb_full or fluid_synth_set_chorus_full and returns a dummy value in those cases, but otherwise delegates to the real prototype.
