fluidsynth | Software synthesizer based on the SoundFont 2 specifications | Audio Utils library

I tried changing qpm. But it doesn't change anything. I want to change the tempo of the notes sequence. I am working on Colab, my notebook can be found here.

I am a beginning programmer playing around with making fractal music in python. I am thinking of using the mingus module to play the notes, however mingus need to have fluidsynth installed. I am trying to install fluidsynth using MacPorts. I have the fluidsynth files. When i run

I used to generate a signed apk from Android Studio and everything was working well until I updated Android Studio to 3.3. It generates an apk but after I try to install it, it says: App Not Installed!

My Trial was by:

1. Click on build
2. Generate Signed Apk
3. Choose APK and click Next
4. Insert the Key Store Path, Key Store Password, Key Alias, Key Password
5. Click Next
6. Choose Release Variant
7. Click Finish

The Apk is generated but it's not signed! What is the problem ?

Here is my app build.gradle

I’ve been toying around to create a functional bash script to solve my problem, but have’t been successful.

The problem:

I need to execute these two scripts from different terminals (or windows using screen):

I am trying to stream and RTSP video only stream from my webcam and consume the feed inside a VM (Docker container) on the same machine.

Here are the commands line args I'm using:

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.

main.py:

I get a FileNotFoundError error while trying to call midi2audio. I am working with Python 3.6 - Anaconda - Windows 10. My .py file is in the same folder, together with the .sf2 and the .mid files. My code is:

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:

I'm on python2-7 I want to get a button in tkinter which stop the reading of the notes created with fluidsynth.

I found that the common solution is to use time.after like here: How do you create a Tkinter GUI stop button to break an infinite loop?

But in my case I can't use it because I need an amount of time between noteon and noteoff to give durations for my notes. Moreover I want to play the notes ONLY if I click on start (and no at the beginning like the solution in the link).

So I created this code but it doesn't work because var_start is always initialized as int:
