Rest Probabilities Added to the GMS

A feature that I have been interested in adding to the GMS for quite a while is rest probabilities. Prior to adding this feature the GMS generated a sequence of notes without ever playing any rests. What’s exciting about the rest probability feature is that now you can add space into the generative phrases that the GMS creates.

Each preset can have a rest probability that ranges from zero to one-hundred. At zero notes will play continually just as it worked prior to adding the feature. At one-hundred only rests will play. Elsewhere in-between the probability of a rest occurring instead of a note is based on comparing a random number between one and one-hundred to the user adjusted setting. If the user setting is less than the randomly selected number then a note is played, otherwise the note is skipped and replaced by a rest of the same duration. I have uploaded a new Mac build for the application (beta 0.11) available for download on the GMS page.

Falling Objects Synchronized to Produce Rhythm

Gravité from Renaud Hallée on Vimeo.

It has been around for a while, but I just came across this very clever piece by Montréal based artist, Renaud Hallée. His composition uses video and sound from falling objects edited together to produce some nice rhythms with a few unexpected twists. Hint: it’s not all tennis balls.

Experimental Music Mondays Part 2

This Monday, March 29, 2010 is the second installment of Experimental Music Mondays curated by John Keston. The line-up this time includes Pawlic (Jesse Pollock) and Terr the Om (Nathan Brende).

Sandwiched between them is Ostracon. This is the name I’m using for the plural version of Ostraka. This instance involves the usual characters, John Keston (aka Ostraka), Graham O’Brien, and the addition of Oliver Grudem who will be interjecting his enigmatic imagery as an input source for the generative musical phrases produced by the GMS.

The venue is the Kitty Cat Klub, 315 14th Avenue SE, Minneapolis, Minnesota. The music starts at 9:00pm.

Four Oscillator Drone Produced with the WSG


What good is a Weird Sound Generator if you’re not using it to make weird sounds? Sometimes it is nice to just hold it on your lap and stroke it gently. That aside, it’s quiet useful once you plug it in and start twiddling the knobs. Here’s a piece I created by tuning the each of the four oscillators on the WSG and then fiddled with the filters. At the same time I made some adjustments to a phaser that I was running it through in Ableton Live and topped it off with ping pong delay.

Experimental Music Mondays Call for Entries

I am curating a series of Experimental Music events hosted by the Kitty Cat Klub in Minneapolis, Minnesota. The first installment is Monday, March 1st, 2010. Subsequent installments are scheduled for the last Monday of every month. For the first show we have three performances.

Ostraka (myself) with Graham O’Brien on drums will be performing using the GMS. Terr the Om (Nathan Brende) will also be performing his distinct breed of electronic music, melding the output from his circuit bent toys with looping and real-time arranging in Ableton Live. Thirdly, Dialsystem consisting of brothers, Graham and Casey O’Brien will likely mesmerize listeners with their ethereal mix of bass, drums, and electronics. Music starts at 9:00pm.

I’m in the process of booking the upcoming events, so if you are a performer of experimental music and would like to get involved, please send your name, artist name, contact information, links to a biography, and links to audio examples to emm [ at ] audiocookbook [ dot ] org.
