Hey hey,
I just released the chord player/generator for tri and tetrachords:
http://juliencoder.de/sound/chord_player-1.0.zip
Or temporary dropbox link:
https://www.dropbox.com/s/y33n323hve9ox3o/chord_player-1.0.zip

there are 43 predefined chords, chosen by index. Their names can be seen using 
m_chord_get_name. Chords can be transposed and inverted. There are different 
note limiting strategies. Chords can be returned as an array of MIDI notes or 
as an array of frequencioes, with optional microtuning support using GEN51 
tuning tables.

A demo is included showing simple MIDI chord playing, cps chord playing, CPS 
plus inversion and microtuning.

I hope the chord choice is adequate for a start. :)

Best wishes,

Jeanette
