I've made some software to help me (and others) make music, principally
and Ableton Live
. Some of it is available here.
Some is free, some costs a small amount.
An online drum machine controlled by your Ableton Push (mk1)
An online metronome fo' keepin' yo' shit tight!
A collection of Max For Live devices I have made
Cross-platform (Win/OS X) tool for transmitting MIDI between computers
Patch editor/management tool for the Akai Miniak synthesiser
In-depth control of Ableton Live using the Korg Microkontrol
Totally meta, see the source code for generating this site!
