What is Wulfcode for? Ostensibly live-coding, but it’s dramatically simplified compared to the SuperCollider and Csound-based environments used by the live-coding community proper. It’s an object-oriented, text-based MIDI sequencer with its own syntax, and a repertoire of commands and structures that allow interesting looping motifs and polyrythmic phrases to be easily generated and manipulated on the fly.

Using Wulfcode involves creating a Note Object - a string of semitone-increment note pitches from 0-f (in hex - the letters a-f correspond to 10-16) - with a given speed multiplier and transposition command, then running that in sync with an incoming MIDI clock. This usually comes from a DAW in ‘play’ mode, which is also accepting incoming MIDI from Wulfcode so it can play those notes from its own softsynths or sampler devices. Creating a Note Object also involves specifying a channel, so if I have e.g. an Ableton Live set with a synth or a sampler on channels 1 to 10, I can target a Note Object at channel 3 by typing and evaluating the following:

mynoteobject c3 {0.23-7c-} 12 0
