How much would it take not to rewrite Overtone in PicoLisp but rather to define a handfull of musical instruments that can easily be used in a music creating PicoLisp program? I'm thinking of a basic rhythm section with a few rhythm instruments (maybe just a snare drum for creating swing and a Cajon and maybe Handclaps for creating Flamenco/World Music beats) and, most important, a (acoustic contra) bass. With some musical instruments available, one could take some inspiration from Overtone and Leipzig and maybe a python program like ,---- | 1.

How to use (picolisp-)aubio to get a score of what I play? Reading about Aubio, it seems that I could plugin my guitar into my computer, record some stuff, and the use Aubio to extract a midi score of what I played (and then use other programs to convert that midi score to conventional musical notation). ,---- | 1. aubio, a library for audio labelling | | aubio.org/ | | + Im Cache | + Ä hnliche Seiten | aubio, a collection of algorithms and tools to extract | musical meaning from audio signals, such as tempo, pitch, and | onset. `---- A fascinating perspective, but how to do that in practice?
