Language for algorithmic generation of MIDI files.

MIDA is a minimalistic language for algorithmic generation of MIDI files. MIDA is not interactive in sense that you cannot control result of its activity in real time, it is intended for producers and should be used with a DAW. MIDA can help you create variative elements in your music in a very simple way. Since MIDI can control a lot of different instruments, power of MIDA is truly great. Main reason for MIDA development is to create software tool that can be used in such a way that does not change established workflow, so people could use familiar plugins and software instruments. The core concept of MIDA is building systems with complex behaviors from very basic and easy-to-understand elements and powerful means of their composition. Currently MIDA can be used to translate source files into .mid files, and also in interactive mode that will help you to understand how MIDA language works. See MIDA Manual for more information.

MIDA

MIDA is a minimalistic declarative language for algorithmic generation of MIDI files. MIDA is not interactive in sense that you cannot control result of its activity in real time, it is intended for producers and should be used with a DAW.

Currently MIDA can be used to translate source files into .mid files, and also in interactive mode that will help you to understand how MIDA language works.

MIDA is a member of Linux Audio consortium.

Installation

1. Install the Haskell Tool Stack.

2. Add ~/.local/bin directory to your PATH, like this:

   # in .bashrc or similar
   export PATH=$HOME/.local/bin:$PATH
   

3. Clone the repo, cd into it, and let stack do its thing:

   $ git clone https://github.com/mrkkrp/mida.git
   $ cd mida
   $ stack build --copy-bins
   

4. Check it out:

   $ mida --version
   MIDA 1.0.0
   

Example

Here is a simple example of MIDA program that demonstrates syntax and declarative nature of the language.

#
# Example of MIDA program
# Tempo ≈ 50
#

dur0   = 6
dur1   = dur0
dur2   = dur0
dur3   = {96 $ 2, 24}
pch0   = c5 {e5 d5 [a5 a5]} $ 2, g5
pch1   = pch0
pch2   = {c2 c3}
pch3   = {c6 d6 e6 f6 g6 a6 b6 c7 e7}
quiet  = {40..80}
normal = quiet + 30
vel0   = quiet
vel1   = quiet
vel2   = 0, normal $ 2, 0
vel3   = normal

How to control other things?

If you're into this sort of thing, you may like my another project, called ALGA. It allows to control automation natively in various DAWs.
