MIDI support on macOS 10.15 Catalina about easyabc

[jwdj]

Hello Dyddye, We are switching to libFluidSynth 2 as sound generating engine. It is also cross platform. It works on Windows now, but I need some help getting it to work on Linux and macOS. Thank you for showing the pygame alternative. It might be useful if FluidSynth is not available/working on macOS. Jan Wybren

I think, the problem is, that QuickTime itself doesn't support MIDI anymore, which is set as default backend for WxMediaPlayer. At least I couldn't open any MIDI file with QuickTime, but with VLC for example. I made some local tests with pygame.mixer, which were sucessful. You have to create a MIDI device on macOS according to this guide: https://stackoverflow.com/a/49543687 Then you can use pygame like this: |import pygame.midi as pypm import pygame.mixer pypm.init() pygame.mixer.init() pygame.mixer.load("PATH_TO_MIDI") pygame.mixer.play() pygame.mixer.stop() | Maybe you can create another backend out of this. To fix the errors to show the MIDI settings dialog, I had to change: |diff --git a/easy_abc.py b/easy_abc.py index cf979f8..98200b9 100644 --- a/easy_abc.py +++ b/easy_abc.py @@ -2724,11 +2724,11 @@ class MidiSettingsFrame(wx.Dialog): outputDevices = [_('None')] outputDeviceIDs = [None] if 'pypm' in globals(): - n = pypm.CountDevices() + n = pypm.get_count() else: n = 0 for i in range(n): - interface, name, input, output, opened = pypm.GetDeviceInfo(i) + interface, name, input, output, opened = pypm.get_device_info(i) if input: inputDevices.append(name) inputDeviceIDs.append(i) | macOS 10.15 Catalina Python 2.7.17 pygame 1.9.6 — You are receiving this because you are subscribed to this thread.

I am trying to look into seeing if I can help with this, but can not find a copy of the pythonmidi package. The link in the readme is not working, is there another source?

I also would like to help with a working Catalina version, if possible.

Hi,
For info, I had some issue with fluidynth on my Mac. With Pygame I could not make the tempo slider taken into account while playing and was difficult to set up also the progress bar.
So I tried another mechanism that could work also on other platforms however only tested on Catalina so I've activated only on Mac.
This is available here: https://github.com/aupfred/EasyABC/tree/playback-mac-mplay
And I've been using the following: https://github.com/jheinen/mplay
