The STO music synthesizer module is a compact Voltage Controlled Oscillator designed for generating SINE waves, Variable wave-SHAPEs, SUB-Octaves, Oscillator SYNC and Linear FM in the analog domain. The Sub-Timbral Oscillator is the more subtle and melodic friend to the DPO's complex harmonic lattice.
 
Triangle Core with outputs for SINE, SUB and Variable SHAPE
Unique Variable SHAPE circuit ripples Even and Odd harmonics for subtle timbral shifts
Linear FM input with Depth control
-EXPOnential input for deep FM, SYNC sweeps or Transposition of sequences
SUB-Oscillator yields max bass
S-Gate input for gating or sync of SUB-Osc. independent of other outputs
Hard SYNC circuit which combined with Linear FM and Variable SHAPE yields harmonically rich sounds
