What I was looking for was probably something similar, but as a (Pico)Lisp, i.e. a real programming language not only for implementation, but to write down the music - instead of text syntax. I don't want to have to build the guitar before I strum a chord, so to say, and the other tools described require so much effort to bring them up and master them.

Open Sound Control
Hey Thorsten, I find the combination of sound & picolisp very interesting Me too! One of my long term goals is to write audio software in PicoLisp. Gotta have the most dynamic language for one of the most dynamic human processes ;) are you aware of "SoundCollider" and the Clojure Libraries "Overtone" and > "Leipzig" > (both on Github)? Yep, I've had a lot of fun with Overtone. It's a source of inspiration for my PicoLisp audio vaporware. I'd like to use it as a jumping off point and then let it evolve into whatever it wants to become. Much learning and many tools to build for the time being, however. There are interesting videos on Youtube about making music with > emacs/vim and clojure Awesome, thanks for sharing. And I noticed that you have another music related picolisp lib on github. Indeed. Unfortunately it's not really usable at this point. I think I've got the basic data types, FFT's, and media sources working, but haven't played with it in a couple weeks now. Another work in progress. 1. 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. I think it would be non-trivial, but certainly not overwhelming. You'd need a way to access your instrument samples (stay tuned, I'm hoping to get the libaubio sampler working in PicoLisp) and then arrange those samples as desired in musical time. Press play and jam on! 2. How to use (picolisp-)aubio to get a score of what I play? I love this idea. I record myself playing piano often... it would be really handy if we had a magical musical score generator! That would save me from having to go back and transcribe the parts I really like. Certainly worth further exploration! 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).

'aubionotes' has returned a bunch of midi notes (64, 108, etc.) and the times at which they occur. To get a complete score, you would need to assemble these values into an actual midi file and then import the midi file into a program that can give you back a score (Lilypond comes to mind). I'm sure there are tools to help with midi writing, but none come to mind. Hope this helps! PS > Very exciting things going on in the PicoLisp universe right now! > Agreed! And thanks for the ideas, I've got some new musical stuff to ponder. Later, Erik
Re: Open Sound Control
I have come the long way round to PicoLisp, and I have been tinkering with livecoding (audio/video, not just programming) for fun. I started with fluxus: www.pawfal.org/fluxus/ It is a great environment where you code and 3D objects show behind your code, and you can drive their parameters from an audio feed or file. It was written in a scheme which is now Racket. I am not a fan of clojure, so I only tried overtone, which is a Clojure wrapper for the Supercollider sound server. They also copied Shadertoy with their 'Shadertone' which allows for the graphics part of the livecoding of music and graphics. I personally like Extempore, but I couldn't get it built on my Windows machine, the OS X install had some issues with Jack and timing, and my Linux distro had a few issues too. All in all, it is very complete and complex, but too much fuss for my skills. http://extempore.moso.com.au/ I have been sticking with learning PicoLisp, and I would like to somehow get it to work with Grace (a single cross-platform executable, that you program music pieces in a Scheme or simplified Scheme called Sal). http://commonmusic.sourceforge.net/ Grace or CM lacks a video creation component or library. I was hoping to hook into the CM libraries with PicoLisp, and then use Alex's z3d.l library to do graphics in PicoLisp. I am not near enough of a programmer to do so, only aware that it can be done (I think?). Livecoding video and audio in a Lisp! Pure heaven...maybe CEPL in PicoLisp??? https://www.youtube.com/watch?v=I0kWZP9L9Kc Have fun!
