I used Audio Paint 3.0 by Nicolas Fournel to create just intonation audio files generated with sines using the graphics as score. Click on them for a full size version. The tuning is essentially a just major 7th add 2 chord. The stereo space is split so that one channel responds to red intensity and the other to blue intensity. Each row of pixels is considered an oscillator and there are 256 of those in each “score”. The audio range is from 55Hz to 2048Hz.
5 note harmonic
