Also, Openmusic. It's a visual patcher, but it is built on Lisp, and you
can write Lisp code for the patches and other items.

What I see in the livecoding scene is the combination of rather complex
programming with rather simplistic music - relentless techno beats ;-)

What would be the minimalistic setup? A midi cmdline tool or a C shared

Or would Supercollider be the easiest thing to work with, now that the

after reading the replies here and reconsidering the mentioned tools I
think I will just use MMA for now, its written in Python and has a
simple syntax and abstracts away all the sound creation stuff. 

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.

Thanks for you answer.

Re: Open Sound Control

[Robert Herman]

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!

I'm not so much interested in the technical (syntheziser) stuff but

to define a handfull of musical instruments that can easily be used in a

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

and create background tracks for practising in PicoLisp. I think that

2. 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).

As far as I understand it, this seems fine to me. In any case,
experimenting with the various ways is the best.

Raspberry and PicoLisp are fine, but only pil32 of course.

For 'emu' I see a speed problem, because that little machine is not the
fastest. On the other hand, most things will happen in the OSC libs, so
the interpreter speed doesn't matter much.

I think it would be better to write native glue functions for pil32.
That is, either a shared library (in the same way the built-in shared
libraries "lib/ext" and "lib/ht" are build) or inline-C code with the
'gcc' function (as an example, see "misc/crc.l" in the PicoLisp distro).

Good to know! I'll make that change, as I'm sure '+Ref' and it's cousins
will be helpful as I move beyond sending a single message to a single
server on the same machine :)

Another question about methods, while we're on the topic... For most of my
'dm's the first argument is implied. For example,

  [dm message-add-int32> (N)
 ... ]

is expected to be called with the message (external symbol) followed by the
number to be added to the message. The message is then accessed by the '(:
ptr)' in the body. Is this the right way to do it, or should I make it more
explicit? Seemed to work as I was playing around with it, so I kept it,
even though I don't fully understand why it works.

Thanks!

I was wondering about this, as Macs are the standard in the music world.
I'd also like to get my Rasperry Pi and similar devices speaking OSC
through PicoLisp. Just gave it a roll with 'emu' on my laptop (a ThinkPad
with Arch Linux) and went through the sample in the GitHub repo. Everything
worked fine for me. I'm hoping later this week I'll have a chance to test
it out on a MacBook and my RasPi.

I don't think the 6 argument limit should be a problem (for this library,
at least); most functions take 0-3 arguments.

Re: Open Sound Control

[Alexander Burger]

Hi Jon,

> Do you know if your library will work with 32-bit PicoLisp?

Unfortunately not, because it uses 'native' calls. As you know, for
pil32 the library calls have to handled a little differently, using glue
functions.

It might work on 'emu'. We must just keep in mind that 'native'
calls under emu cannot pass more than 6 arguments to a function.

I think the memory use should not be a problem here.


A small note about the places where you assign a value to 'ptr':

   (=: ptr
   (liblo~ffi ...

This works, because 'ptr' is defined as a plain number property

   (rel ptr (+Number))

without any entity/relation side effects. But if you make, for example,
an index later

   (rel ptr (+Ref +Number))

then it will break because the index will not be maintained when a value
is assigned.

So in general, you should use 'put>' to assign properties to entities:

   (put> This 'ptr

Hi Erik,

Do you know if your library will work with 32-bit PicoLisp? I’m a Mac user, and 
32-bit (and Ersatz) is the only PicoLisp version that I can use.

I have no experience with OSC (Open Sound Control is a protocol for 
communication among computers, sound synthesizers, and other multimedia devices 
that is optimized for modern networking technology), but I have played a little 
with MIDI music. At the moment I’m trying out Web Audio.

Hi all,

I'm working on my first PicoLisp library, native C bindings for Liblo. What I 
have so far, which is enough for the most basic use case, can be found at:

  https://github.com/erdg/picolisp-osc

The file 'liblo.l' contains the direct ffi-bindings to the C library. I stole 
Alex Williams' idea of a "rule-based solution" from his 'picolisp-json' 
library; it's a great way to get up and running with C functions at the repl.

From there, I decided to scoop it all up into the PicoLisp DB. The files 
'server.l', 'address.l', and 'message.l' contain the code for this. They should 
probably be condensed into one file, 'osc.l', but that hasn't happened yet. You 
can follow along with a sample repl session in the README.

Now I'm wondering if this is a worthwhile path to pursue. I like the idea of 
using the PicoLisp DB, as one could be able to query a bunch of OSC servers and 
their methods, keep a log of messages sent/received, etc., all from PicoLisp. 
But the whole thing could be terribly redundant as far as memory use is 
concerned(?), and because a lot of that functionality exists in the C library 
already. I'm still learning how PicoLisp and C work together.

I'd love any feedback! Apologies in advance, it's all pretty rough right now... 
I've never written a library before, in any language, and this one is nowhere 
near complete. You'll need liblo installed prior, as I have no Makefile magic 
happening yet.

If interested, more info about OSC can be found here:

Many thanks!
