Synthesis Technology E330 Multimode VCO

Three VCO engines in one knob set: 2-op FM, morphing wavetable, cloud

14 HP Eurorack module

The E330 is a 14HP digital VCO from Synthesis Technology that packs three completely different synthesis engines into a single module: 2-operator FM (a stripped-down Yamaha-style FM voice), 32-wavetable morphing (Z-axis blends through E350 wavetables), and a 4-oscillator Cloud generator (a slim variant of the E340 with Spread plus filtered-noise chaos). A front-panel three-position toggle picks the engine, and the same MODULATION A/B knobs and CV jacks change function depending on the mode, giving each engine its own pair of voicing controls. Two outputs (OUT 1 and OUT 2) deliver different aspects of each mode, so you can patch the modulator/sub waveform back into the VCO or mix it for additional harmonics.

Features

Three switchable synthesis engines: 2-op FM, morphing wavetable, 4-oscillator cloud

Two simultaneous outputs (OUT 1 / OUT 2) with engine-specific function

32-wavetable morphing bank borrowed from the E350 Morphing Terrarium

Yamaha-style 2-operator FM with quantised 0.125-step ratio table

4-VCO Cloud mode with Spread (detune) and Chaos (filtered-noise FM)

Hard-sync input active in all three engine modes (>0.45V threshold)

1V/Oct tracking with internal scaling trimmer

Exponential FM input with dedicated attenuator (DC to 8kHz)

Two CV inputs (MOD A / MOD B) summed with the MODULATION A/B knobs

16Hz to 18kHz frequency range on OUT 1, 2Hz to ~21kHz on OUT 2

16-bit / 41kHz internal DSP — high FM index can produce intentional aliasing

Reverse-supply diodes on the +/-12V Eurorack header
