musAIc

Interface for composing music with an A.I. musician.

Currently in active development.

Basic Installation

Requirements

It is recommended to use Python version 3.6.x since I have encountered issues with installing tensorflow and keras on later versions of Python. The best way of making this easy is to use isolated environments, such as with pyenv.

Linux / Mac

1. $ git clone this repository to somewhere in your home directory

2. Make sure you are in a Python 3.6.x environment (e.g. with global $ python3 -v is 3.6.x, or with something like pyenv)

3. Install the required packages with $ pip install -r requirements/base.txt

4. Launch musAIc with $ python src/main/python/main.py

Windows

1. Install git from here

2. Make sure Python 3.6.8 (64-bit) is installed and added to PATH (get the installer here)

3. Open Windows PowerShell (right-click the Start button and select from the menu, or search powershell.exe) and cd to which directory will host musAIc

4. $ git clone https://github.com/Denbergvanthijs/musaic.git this repository in some folder.

5. pip install wheel cython

6. pip install --upgrade pip

7. pip install ./requirements/rtmidi_python-0.2.2-cp36-cp36m-win_amd64.whl

8. Install the required packages with $ pip install -r requirements/base.txt

9. Launch musAIc with $ python src/main/python/main.py

Detailed Instructions

For complete beginners in Python and Terminal

Mac

1. Open Terminal from the Finder.

2. Install XCode, Homebrew and Python 3.X. A simple guide that covers these can be found here. Follow the steps up until the Virtual Environments stuff (I recommend something easier in the next step)

3. Install pyenv:

   brew install pyenv openssl readline sqlite3 xz zlib
   echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.bash_profile

   Restart the Terminal.

4. Create a folder and navigate to where you would like to install musAIc (this is done with the commands $ mkdir DirectoryName/ to make directories and $ cd path/to/directory to move into a directory). This could be in somewhere like Projects/, Music/Tools/, or whatever you like to do to organise your projects.

5. Download (clone) this repository in this folder with the command, and move into the folder:

   git clone https://github.com/Denbergvanthijs/musaic.git
   cd musaic

6. Create a virtual environment and install dependencies:

   pyenv install 3.6.8
   pyenv local 3.6.8

   (Verify that the command $ pyenv which python returns some path with 3.6.8 somewhere in it)

7. Finally, launch musAIc with the command $ python src/main/python/main.py

8. Bonus: to make it easier to start musAIc without using the terminal, first copy the output of the command $ pwd in the directory you launched musAIc from. Then, create a new file with your favourite text editor called musaic.sh and put in the following with the path you just copied:

   #!/bin/bash
   
   cd PATH_YOU_JUST_COPIED
   python src/main/python/main.py &

   Save this file to Desktop, then in Terminal run the command:

   sudo chmod +x ~/Desktop/musaic.py

   (If you are prompted to enter your password, do so and press enter)

   Now, to launch musAIc just double click musaic.sh!

Usage

Work In Progress

Using MIDI out

1. Make sure whichever MIDI device you wish to use (either through a soundcard, USB or a virtual MIDI cable) is initialised and working before starting musAIc

2. Once started click options, tick the box next to MIDI, then select your MIDI device from the dropdown menu. Optionally you can send the MIDI clock signal too (on by default), however, this is largely untested and may act weird.

Note: there is also a small bug where re-opening the options dialog will reset which MIDI device it will use, so make sure to select the desired one again.

Changing the AI musicia

musAIc is currently bundled with two neural networks: the original developed in 2019 (affectionately named VERSION 9), and the WIP pop star EUROAI. In the future they (and others!) would be selectable from within the GUI, however for now the only way is to change the PLAYER global variable in src/main/python/network.py to either 1 for VERSION_9, 2 for EUROAI, or 0 for a random number generator (for development/debugging, will not load tensorflow).

Issues

• The MIDI box in the options menu needs to be selected to hear sounds
• MusAIc will stop generating new bars if all five styles (qb, eb, lb, fb, tb) are de-selected
