[sdiy] Yamaha CS-15D schematic

Has anyone seen the schematic diagram for this rather unusual preset /
variable monosynth? In one sense it's a more capable synthesizer than any
of the CS-5, 10, 15 bunch, even the CS-30, since it has two VCOs, two VCFs,
2 VCAs and 4 envelope generators. However, half of that is stuck behind
preset sounds only, and the modulation capabilities are inferior to all the
previous synthesizers.

A prime candidate for modification and modularising, you might say!
