Hi - I'm involved in building a lot of wheels for the Python scientific stack - and I was talking to someone who needs pyo wheels for their binary install.

Is there any chance of generating pyo wheels to install via pip / pypi?

Do you want any help doing that? I have lots of experience doing that kind of thing.

I am trying tot install Pyo on my new Raspberry Pi 4 with pip3. I get the following errors:

src/engine/pyomodule.c:24:10: fatal error: sndfile.h: No such file or directory #include "sndfile.h" compilation terminated.

Pyo crashes python on s = Server().boot() on windows whenever a midi input device is connected. Also displays no error messages. Works perfectly fine on Ubuntu 18.04. Also it is unable to use asio host api. The only api that seems to be working is mme, which however crashes whenever there is a midi input

`* Checking for any available audio input... *

• Checking audio output hosts... *

• Testing mme... *

• Testing directsound... *

• Testing asio... * Pyo can't find audio host 'asio'. Currently available hosts are: apis: mme windows directsound windows wasapi windows wdm-ks

• Testing wasapi... * Portaudio error in Pa_OpenStream: Invalid device Portaudio error in Pa_CloseStream (pa_deinit): PortAudio not initialized Portaudio error in Pa_Terminate (pa_deinit): PortAudio not initialized

• Testing wdm-ks... *

Results

Duplex mode OK! Initialize the Server with duplex=1 as argument.

Host: mme ==> OK! Host: directsound ==> OK! Host: asio ==> OK! Host: wasapi ==> Failed... Host: wdm-ks ==> OK! Initialize the Server with the desired host given to winhost argument.

Finished!`

Let me know if you need any more info. Any help you can provide to fix this is greatly appreciated. Thanks :)

I'm trying to make it work on any python3 version, got stuck here.

Traceback (most recent call last): File "02-sine-tone.py", line 7, in <module> from pyo import * File "C:\Python35-32\lib\site-packages\pyo.py", line 21, in <module> import pyolib.analysis as analysis File "C:\Python35-32\lib\site-packages\pyolib\analysis.py", line 32, in <module> from ._core import * File "C:\Python35-32\lib\site-packages\pyolib\_core.py", line 57, in <module> from _pyo import * ImportError: DLL load failed: The specified module could not be found.

I am trying to get midi working with Pyo on OS X. So far no luck. The samples I tried gave me a midi note in once, then nothing. The pm_list_devices() gives me a command prompt (>) BTW, I cannot use wxPython. I installed it for Python 3.5 (Anaconda) but get this error: This program needs access to the screen. Please run with a Framework build of python, and only when you are logged in on the main display of your Mac.

I'm just beginning to grasp python, but am at the point where I've installed pyo through pip into python 3.9.10. (same for 3.8.9) However, by the looks of my error, there is a missing file _pyo in the .lib folder.

I run only 'import pyo' and get the following error:

Traceback (most recent call last): File "<tmp 1>", line 1, in import pyo File "C:\Users\Christopher\AppData\Roaming\Python\Python39\site-packages\pyo_init_.py", line 27, in from .lib import analysis as analysis File "C:\Users\Christopher\AppData\Roaming\Python\Python39\site-packages\pyo\lib\analysis.py", line 32, in from ._core import * File "C:\Users\Christopher\AppData\Roaming\Python\Python39\site-packages\pyo\lib_core.py", line 66, in from .._pyo import * ImportError: DLL load failed while importing _pyo: The specified module could not be found.

Same error if I copy the first example script from your setup guide. http://ajaxsoundstudio.com/pyodoc/gettingstarted.html

I tried looking for the '..pyo\lib_pyo.py' in github (https://github.com/belangeo/pyo/tree/master/pyo/lib) and its not there, so maybe there isn't supposed to be one, but at this point I'm at a loss and really don't want to give up this project I haven't even started.

-I've set environment variables to my python modules & python scripts. -I've set pythonPath to the correct directory in my IDE (I'm using Pyzo). -I've reinstalled everything a few times.

Have tried with SfPlayer and SfMarker. Code:

from pyo import *

s = Server().boot()
s.start()
sf = SfMarkerLooper("/sample.wav", speed=[.999,1], mul=.3).out()
s.gui(locals())

Terminal Output:

Traceback (most recent call last):
  File "fm_synth.py", line 5, in <module>
    sf = SfMarkerLooper("/sample.wav", speed=[.999,1], mul=.3).out()
  File "/Users/morganvisnesky/anaconda3/lib/python3.6/site-packages/pyolib/players.py", line 514, in __init__
    self._snd_size, self._dur, self._snd_sr, self._snd_chnls, _format, _type = sndinfo(path[0])
TypeError: 'NoneType' object is not iterable

Also getting this message every time i run a pyo script, but using pythonw filename.py at the terminal seems to allow everything to work with the exception of these sample related calls:

"WARNING: 140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h."

Hey, I compiled from source on arch and unable to boot server here's the message I got:

ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib pcm_route.c:869:(find_matching_chmap) Found no matching channel map Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock

Why is it asking for jack if I compiled without it? And if I run with jack the message is:

On my Windows system I finally had pyo running. (Python3.7, wxPython installed) Now I wanted to try the funnysynth example and I get: C:\Python37\python.exe C:/Users/toosb/PycharmProjects/pyoo/funnysynth.py Traceback (most recent call last): File "C:/Users/toosb/PycharmProjects/pyoo/funnysynth.py", line 3, in from pyolib._wxwidgets import VuMeter, ControlSlider File "C:\Python37\lib\site-packages\pyolib_wxwidgets.py", line 25, in from ._core import rescale File "C:\Python37\lib\site-packages\pyolib_core.py", line 58, in from _pyo import * ModuleNotFoundError: No module named '_pyo'

an error in an example code of the doc:

that should be:

found here: How to improve performance of your pyo programs, under the subtitle of "Use the subprocess or multiprocessing modules"

Linux (Arch,5.3-rc-latest from git), latest pyo from pypi.

I have no inputs available. Default (set to portaudio for some reason) wouldn't work at all, server wouldn't boot complaining about input channels < 2, both when running pulseaudio only and jack+pulseaudio. Setting duplex=0 didn't help. I did manage to get it to boot once by hard setting input channels in the jack config, but output didn't work.

Setting audio='jack' and duplex=0 didn't work either. It now segfaults because it can't connect to input ports = 'system'. This was supposed to be partially fixed via #15, since pyo has no reason to connect to inputs when duplex=0, but the fix does not work for me.

This is a problem, because:

1. It is a common setup and having it be broken is a barrier for people trying out pyo as well as those who wish to distribute projects using pyo.
2. duplex=0 doesn't work as intended.
3. A segfault is not an acceptable failure mode.

I've managed to work around the issue with:

s = Server(duplex=0,audio='jack')
s.setJackAuto(False,False)
s.boot()
... connect to output programmatically or manually ...

However, this is imo unsatisfactory, especially since it's not documented anywhere. I recall having this same issue when attempting to try out pyo many months back, and not having the time/motivation to debug at the time, concluded that it wasn't worth the time to do so just to try it out.

This is not intended to be harsh, btw, although my LKML-influenced style might make it read that way ;) Please assume that I'm thrilled that someone took the time to create this.

I've just built the pyo package on macOS (13.1 arm and 10.4 intel) with the current version successfully (by fixing self.pos issue) but _.ctrl() does not work correctly. To reproduce run for instance pyo/examples/03-generators/02-band-limited-oscs.py; after start a sound is produced but the LFO controls freq and mul do not work. If you change e.g. freq the sound does not change unless you close the control window.

Hello. I strongly wish to try this beautiful module but I'm not able to install on Windows 11, under my version of Python which is the 3.11.0 I tried to follow the user guide to install but I have several errors with pip. How can I do? Many thanks. Gabe.

I am trying to use the ASIO driver, as I need very low latency with audio being recorded straight in, and sent straight out again. However, when doing this, this error comes up:

Portaudio error in Pa_OpenStream: Invalid sample rate

Here is my code:

from pyo import *
pa_list_devices()
s = Server(winhost="asio", sr=44100)
s.boot()
s.start()
mic = Input().play().out()
h = Harmonizer(mic).out()


while True:
    pass

I have tried with 44100, 48000, and many other sample rates. My settings show my microphone is 44100, 2 channel 16bit.

I am using WXpython 4.2 , the Scope provide an error but the program is working. The error appears each time the scope box is resized. I read that pyo support Wxpython 4.0.7 but I do not succeed in going back to this release. ( Mac OS 12.6 ) Is it still the case or 4.2 is now supported ?

I do not succeed in using SfPlayer. When I run the example or any other program I get the following error. I am using Mac OS 12.6. Python 3.1 It is working when loading the file in ram and reading the table.

The above exception was the direct cause of the following exception:

When building a wheel on the darwin platform, setup.py expects various libraries to be in the non-existent folder temp_libs. It would be helpful to include some information about the intended use.

The following works for me (Mac OS X 12.5.1):

port install portaudio portmidi libsndfile liblo
ln -s /opt/local/lib temp_libs
python setup.py bdist_wheel

Otherwise I get a rather cryptic error message

error: can't copy 'temp_libs/liblo.7.dylib': doesn't exist or not a regular file

(At least it was cryptic until I figured out that setup.py was looking for temp_libs.)
