We're gearheads at heart, but we also build our own tools when existing software/hardware feels inadequate. Here are some things we've made.
A Toy Software Synth written in Python that alllows you to build your own synths
Web interface to perform live with IBNIZ
A Generative Looper for Live performance
A table based esoSynth (esoteric Synthesizer)
a diminutive virtual machine with 95 character memory that you edit live to create sonic patches
A 16 channel assignable midi controller
