week 9 code

here’s firmata code from class:  avsys_wk9

Mar 11



a) create a 140 character (or less) composition using super collider.  Take a look at the sc140 albumbs for inspiration.

b) using super collider or chuck and OSC, create a audio visual composition where the sound is produced in a separate program and OF controls the visuals.     You can recode your sequencer to use these tools if you want.


extra credit — try to hook as many software together using OSC as you can.   Learn about the OSC protocol, and experiment.  What can you hook up, and what kind of interesting app->app communications can you make.

supercollider code

some good resources:
here’s the super collider code we were testing in class
and the two open sound control “OSC” based examples  (pc people, you’ll need to duplicate an OSC example from the addonsExamples folder, as this code uses the ofxOsc addon):
(these two examples are for the corresponding synth def code in the text file)

Homework + Sequencer Links

1. Compose a song with an existing sequencer
2. Create an interesting sequencer (with code).

Sequencer Notes:

sound notation separate from sound. some control of tone, but not organic control

–Music Boxes–
origins in the 14th century will bell makers, got big in the 18th century with musical snuff boxes built by watchmakers. essentially pins on a revolving cylinder that pluck teeth of a steel comb when they can poke through holes in a paper.

–late 1800’s and the advent of advanced mechanics and pneumatics led to player pianos–

also from this period was the invention of the telegraph and tickertape, although not used for music, it was essentially a character sequencer used for transmitting data, and many early models looked like actual pianos. it’s interesting to think how we still call what we type on keyboards, but this was a term that once came from music (and in fact still refers to electronic pianos as well).

1870 – 1960 :

–electric organs – 1930s
while i would only say these were not really sequencers since they didn’t record and playback, they paved the way to:

–the 60’s – 80’s where we start to see the first of what i would say is a modern definition of sequencers, starting with:

–drum machines: Wurlitzer – sideman

–70’s standalone sequencers (thanks Brett Burton)
This was before the advent of MIDI and made use of Control Voltage to communicate with an electronic organ or synthesizer. It made no sounds of it’s own and was solely for the purpose of composing and performing music.

–1974 – computer hums own music article: electronic organs and music programed by punch cards through a computer. now the definition of sequencers is starting to get a little abstract.

–1980’s casio pt-1
buttons on the right are a one step, tap alternatively to let you step through the sequence

–MOD –
1987 – Ultimate Soundtracker for Amiga

Milkytracker –

we also see the advent of various other computer music formats like midi and o/c.

we also start to see sequencers that are based not just on linear steps forward, but also all sorts of other things like spacial systems, or various natural phenomena
