Prelude in Haskell

The music is minimal, but the terminals are fun to watch. This one’s got a little language for making notes and beats that is immediately obvious, if you can manage to read the screen. (See also: the betablocker sneak peek.)

I’ve been longing to get more into this.

I made a random arpegiator in ruby, but I only managed to make it export MIDI files, not been able to play the sounds live, through a MIDI Channel on OSX. Any ideas?

In the sam vein you’ve got Impromptu on OS X, an midi sequencer + graphic output, in a Scheme environment, thought for live performance, by editing the code on the fly…

abscond: I’m sure something could be cooked up with dl/import and some API calls from IOKit.

Maybe this? Some Cocoa to access CoreAudio.

The planets are aligned by Jove! I take a break from reading “The Haskell School of Expression: learning functional programming through multimedia” to download Haskore and this appears!

Coo, thanks for linking to my screencast, I have a bit more at my website. On the subject of livecoding we’re putting together a livecoding festival in Sheffield, UK this July.

I think today I will try and make something that will at least let me type a note sequence and get it played. I might just start with RubyCocoa, then try and get it on DL, because I really don’t grok DL yet.

By the way, betablocker is by Dave Griffiths, check out Al-Jazari! And more about livecoding at the Temporary Organisation for the Promotion of Live Algorithm Programming.

A final plug, Dave and I are two thirds of slub.

yaxu: Great to hear from ya. The robots and thought bubbles of Al-Jazari are pleasant and there’s a wonderful batch of scheme that I’m sure all of the readers will have some fun tinkering with.

Got any little hacks for us? Like one of your handiest routines to leave us agape.

I’m not very good at ruby but

ruby -e 'c = []; (0 .. 1024).map {rand}.sort{|a, b| c.push(a, b); a <=> b}; print c.pack("f*")' > /dev/dsp

My attempts fell through. Partially because the AudioToolbox documentation is weak, and partially because I got totally sidetracked by impromptu. That is a bitchin program!

I always liked the Just-In-Time Library for SuperCollider. You can make some noise real quick.

Ok, tonight I sat down with JRuby, and hacked out a ruby interface to a MIDI synthesizer. It’s not quite complete yet, I am gonna add some DSL like stuff, and complete the DRb wrapper.

That was as far as I could get tonight. It needs the ability to do looping notes properly, and to play more than one note at a time. But it makes noise, and is fun! Try it!
