I spent a couple hours this evening putting together a track that uses some algorithmically generated (although I use that term loosely, as most of the variation is from randomness…see this post for details) sound. I recorded some of that sound from a Pure Data patch. One thing to note is that the sound is all tempo synced to 120 bpm, but the rhythms vary randomly within that, but always on beat. So the rhythms can be on any 32nd note or 16th note, etc. Then I imported this into Ableton Live 7 (i have 8 also but it is really buggy at the moment, grrr).

This is the second installment of a sound a day. It is a bit longer. I have now implemented a continuous randomization of the note values and durations in the sequencer, as well as the delay times in the K-S algorithm. It has an intriguing quality now. It never repeats and yet is quite rhythmic which makes your mind try to assign patterns. There are fleeting bits of pattern that are tantalizing without actually going anywhere and yet I find it quite fascinating to listen to. I have created two copies with independent timings and sent one to the left channel and one the right. The polyrhythms and occasional harmony add to the nagging feeling that something is happening that makes some sense, and yet it is driven by random number generators and filtered noise generators. It feels a bit fractal to me although there is nothing really fractal about it. It will be interesting to see if adding a fractal nature to the “patterns” sounds more interesting. By this I mean creating nested rhythmical and harmonic blocks. I’ll give it a go and post the results here soon.
Again this is the dry sound coming out of Pure Data. I have attached the patch for anyone who is interested.
