MOTM

4-simple voices ( single VCO>>VCF>>VCA) in a harmonic series tuning. The 2 lower 
notes use the MOTM-440 VCF, the 2 upper use the MOTM-490 VCF. The microtuning 
tables are stored in the MOTM-650 4-channel MIDI-CV (prototype) and the 
"sequences" are played using the built-in dual arpeggiators in a 3/2 ratio. 
Slight echo/delay effects in the 02R96 recorder. Recorded live, 4 tracks (1 per 
note/voice). Up to 16 tuning tables can be loaded in at once into the '650 via 
MIDI Tuning Dump.

You can hear how the notes are 'bunched up' at the top frequencies, then spread 
out as the notes are lower in pitch.
