more audio recordings of my twitter sctweets. see twitter.com/redFrik and this post.
normally you run these lines of code (140 characters) in supercollider and it will play you some kind of generative music or soundscape (also graphics in rare cases). here i've recorded a few for those who are too lazy to install sc.
this one is using the built in .fib (as in fibonacci) method to generate pitches (\degree) for the Pbind. the Pbind in it self is quite boring to listen to, so by playing it out on audio bus 8 and then making a small distortion+echo effect synth reading from bus 8, we get a much more interesting sound.
again using the built in fibonacci method to generate patterns. here every 8th bar the pattern is scrambled (Dshuf), and in every 8th bar period the first 2 bars are transposed by a strange trick running the melody pattern (i.e. the frequencies) through a CombN.
here is something that sounds a bit like a couple of trombones playing a riff in a reverberant room. the riff just goes on and on and is made from a pair of slowly changing LFPar oscillators, scaled, offset and rounded to the nearest 50Hz.
sounds a bit like punk rock in 6/8 time signature. the crispness comes from the > BrownNoise combo and the rhythms from the Pulse. overall melody is the slowly running LFPar oscillator stored in variable f. note that this tweet only works in sc version 3.5 and above.
an ever rising tone cluster with some clicks. this is built using a localin/localout feedback chain. there are plateaus where one thinks the maximum frequency is reached, but those are only temporary and after a while the tone starts to rise again.
here the cutoff frequency of a BRF (band reject filter) is modulated with a SinOsc. the cutoff varies between 1 and 99 Hz in the left channel, and 1 and 100 Hz in the right channel. the BRF goes wild and outputs totally crazy sounds when modulated in this matter - just like the BPF used to behave in old sc versions (3.3 and earlier).
a deep fat bass. it sounds as lovely in a big speaker system as it sounds poor in laptop speakers. the patch is mainly doing phase modulation on a SinOsc with tanh distortion.
this tweet sounds much like a field recording. the noise comes from an exploding BRF (band reject filter) that is wrapped in a Limiter so that it keeps in range. last a GVerb is adding a metallic quality reverb to the overall sound.
this was coded, believe it or not, within a 5min time limit and under water pistol threat (part of sc2012 keynote talk in london). again it's a BRF misbehaving run through a comb delay with short modulated delaytime (from 0 to 0.1).
a quite poor tweet. the rhythms are not so interesting and it also have the problem of running out and stopping after a few seconds. anyway, the principle is that a BRF is generating strange sounds that phase modulate a SinOsc, that in turn goes through a ringing filter (Ringz). i only wanted to record it so that when someone fixes the BRF in some upcoming supercollider version, i can go back and listen to how it could sound.
super annoying little thing. it is using the values of the ascii characters in the string "SUPERCOLLIDER" which is [83, 85, 80, 69, 82, 67, 79, 76, 76, 73, 68, 69, 82]. this is played in sequence and transposed and detuned. maybe a candidate for the official supercollider theme song?
very intense sounding tweet.
an even more intense sounding tweet.
this patch is heavy on the cpu. it consists of a synth with nested GVerbs all with random settings for roomsize and reverberation time. synths play for 6 seconds and then fades out over 5 seconds as another synth, with different reverb settings start. the result is overlapping sounds and quite dense texture.
a rhythmic tweet. gets a bit annoying after a while but there are some nice details in there.
phasing melody in left and right channels. every 7th note has a slightly different timbre (the 0!6++500 part) and every time one starts this tweet the melody changes (the Dshuf((0..7) part). the phasing is done with two Saw oscillators running at 9 and 9.01Hz. they are in turn used as triggers for the timbre and melody sequences (the two Demand ugens).
