alga: Algorithmic automation for various DAWs

[ deprecated, gpl, language, library, program ] [ Propose Tags ]

Deprecated.

How to algorithmically control every aspect of music using familiar, robust tools: plugins, DAWs, etc. that have not been built with this in mind? I've partially solved the problem in MIDA — program that generates MIDI files using very simple and symmetric language. However, even though MIDA is a fine tool to create scores, it's not sufficient if you want to control everything. Initially I thought I could find some plugins that can algorithmically control other plugins, but there are no decent tools of this sort. How automation is handled in a traditional DAW? Well, you draw it in a separate track. Wouldn't it be a good idea to algorithmically perform exactly that: drawing of the automation track. This is simpler than it may seem: many DAWs allow to export tracks in XML format, and this is all we need to start our hacking.

How to algorithmically control every aspect of music using familiar, robust tools: plugins, DAWs, etc. that have not been built with this in mind? I've partially solved the problem in MIDA — program that generates MIDI files using simple, symmetric, declarative language. However, even though MIDA is a fine tool to create scores, it's not sufficient if you want to control everything. Initially I thought I could find some plugins that can algorithmically control other plugins, but there are no decent tools of this sort. How automation is handled in a traditional DAW? Well, you draw it in a separate track. Wouldn't it be a good idea to algorithmically perform exactly that — drawing of the automation track? This is simpler than it may seem: many DAWs allow to export tracks in XML format, and this is all we need to start our hacking.

How does it work?

You export your tracks in XML format, write some scripts in MIDA-like language and patch the XML file. Then you can import the files back, they will (hopefully) have fancy automation tracks in place.

Installation

Install the Haskell Tool Stack.

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

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

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

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

Check it out:
```
$ alga --version
ALGA 0.2.0
```

Example

ALGA is a simple declarative language. Just to get feeling of it:

#
# Example of ALGA program
#

my_track.pan  = {0..16} / 16 $ [{2}]
my_track.pand = 1/8, 0

This thing changes position of stereo-panorama for track named my_track. There are 16 possible values from left to right. Panorama is changed instantly, every eighth note.

You can control volume, panorama, mute, input gain, all parameters of send slots, insertion slots, and software synths. Changes can be applied to audio tracks, group tracks, instrument tracks, and effect tracks.

See ALGA Manual for more information.
