The Make Noise STO Voltage Controlled Oscillator Synth 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. The STO will yield harmonically rich textures through the use of Hard Sync, Linear FM and Variable Shape, but this VCO seems destined for melody. The STO uses a Triangle Core and has outputs for SINE, SUB and Variable Shape. The SINE is shaped from the Triangle using the same circuit used on the DPO. The Sub-Oscillator has its own gate input that lets the user turn it on/ off at will. The Variable SHAPE ripples both Even and Odd Harmonics resulting subtle timbral shifts where the fundamental frequency is never masked. When combined with the Sub-Oscillator output (at the input of the MMG, for example) this makes for a rich, strong melodic voice.
