First L!vE K@ding session!

As promised, here’s my first live coding screencast! The video unfortunately turned out to be not very good: ffmpeg on Linux failed me miserably. I thought it was worth sharing anyways, so, here it is. 😉
Some comments: I have used some SynthDefs that I have already prepared and some samples that I have loaded beforehand. This is achieved by the tabs “initialize” and “synths” that you see in the video. This is not a “blank page” approach to live coding, but it’s what I have realized works for me, since I am more interested in improvising patterns than the actual sound synthesis (which I also did in this session, by the way). In particular, one of the SynthDefs which I am really liking is \looper, a custom made looper which allows me to capture audio from other synths and control its parameters to get nice glitchy patterns. I’m really liking it. :) On the other end, \pad_fm is a very simple pad with fm modulation. Of course, if anybody is interested in these SynthDefs I will certainly share.
Oh, also almost everything happens in ProxySpace.
Enjoy 😉

Piano, patterns and gestures

I always loved piano as a kid, but for life circumstances I could never study it.  Ended studying guitar instead. Here’s a little code in Supercollider, exploring piano improvisation and “gestural” phrasing.

MIDIClient.init;

~mOut = MIDIOut.new(3);

//Set the scale to be Cmajor
~scale=[0,2,4,5,7,9,11];

//Define pattern proxies which will be modified by the task t below

a=PatternProxy(Pxrand([3,3,3,1,3,3],inf));
b=PatternProxy(Pseq([1/2],inf));
r=PatternProxy(Pseq([12],inf));
n=Prand([4,8,16],inf).asStream;

t=Task({
Pdef(\x,Pbind(\type,\midi,\chan,0,
          \midiout,~mOut,
          \scale,~scale,
          \root,-12,
          \degree,Pxrand([[0,3,5],[3,5,7],[4,6,8],[5,7,11]],inf),
          \legato,1,
          \amp,[{rrand(0.6,0.8)},{rrand(0.5,0.6)},{rrand(0.5,0.6)}]*0.7,    \dur,Prand([Pseq([1,1,1,1],1),Pseq([1,1,2],1),Pseq([1,2,1],1)],inf))).play(quant:1);

Pdef(\y,Pbind(\type,\midi,\chan,0,
          \midiout,~mOut,
          \scale,~scale,
          \root,r,
          \degree,a,
          \legato,1,
          \amp,{rrand(0.5,0.6)},
\dur,b)).play(quant:1);

10.wait;

t=Task({
    inf.do({
        if (0.7.coin,{ 
         c=[[3,0,7,1,9,11,0,4],[[3,7],0,7,Rest,9,[0,11],0,4]].choose.scramble;
             r.source=Pseq([[12,24].wchoose([0.7,0.3])],inf);
         d=n.next;
             a.source=Pseq([Pxrand(c,d),Pxrand([3,3,3,1,3,3],inf)]);
             b.source=Pseq([Pseq([1/8],d),Pseq([1/2],inf)]);
           });
       rrand(3,4).wait;})}).play(quant:1);
    };
).play(quant:1);

I’ve used a PatternProxy for the various notes degrees, velocity and duration, so to be able to modify it on the fly via the Task t, which controls the improvised part.

I came later to realize that it would be probably better to use Pfindur, instead that a Pseq to release the phrasing… I’ll try that soon. 😉

The MIDI has been routed to Ableton Live, and what you can hear in the following is its standard piano instrument.

Audio clip: Adobe Flash Player (version 9 or above) is required to play this audio clip. Download the latest version here. You also need to have JavaScript enabled in your browser.

For something amazing about  coding, piano and improvisation check Andrew Sorensen work with Impromptu. Superb.
