midi Sequencer v0.1.1

A simple openFrameworks project that generates a four note sequence given a midi note in.

• Harmonies in the sequence can be controlled via modename and root selection
• Rhythmic proportions controlled via position of the HarmonicFields along the x axis
• Probability of a specific step controlled by position along the y axis

Compilation

cd $OFROOT/apps/myApps/
git clone git@github.com:adammccartney/midiSequencer.git
cd midiSequencer 
make
make RunRelease

Usage

It's intended to be used as a single component in a modular toolchain. midi Sequencer receives notes from a midi port and communicates the generated sequencer over OSC to some other program (chuck/supercollider/puredata), which then might do something useful (like make some control messages for an instrument).

Pitch Classes

enharmonics discounted out of love for the robots

/[a-g][s]?/

example

• cs := c sharp

12 pitch classes in total: {c, cs, d, ds, e, f, fs, g, gs, a, as, b}

Modes

legend for intervals

/[M|m|P][digit]/

M       := major
m       := minor
P       := perfect
[digit] := diatonic interval

example

• M2 = major second = 2 semitones
• m3 = minor third = 3 semitones
• P4 = perfect fourth = 5 semitones
