Synthesis Technology E330 Multimode VCO
The Synthesis Technology E330 Multimode VCO is a low-cost digital oscillator with 3 unique operating modes: 2-operator FM, Morphing Wavetable or a 4-oscillator Cloud Generator (similar to the E340 module).
The module provides 2 simultaneous outputs (OUT 1 and OUT 2), that change based on the MODE selected. Each output has an independent, corresponding modulation CV input and initial panel setting. The function of these 2 CVs varies based on the MODE.
2-OP FM is a 2 "operator" (to use Yamaha's terminology) FM (frequency modulation) where a sine VCO that is the 'pitch' (called the carrier) is FM'd by another sine VCO (the modulator). These sine VCOs are internally generated by the E330. OUT 1 has the pitched, FM'd result, and OUT 2 has the modulation sine wave. The MODULATION A panel/CV is the FM 'depth' or 'index' and varies from 0% (OUT A is a pure sine) to over 400% (4th harmonic overtones). The MODULATION B panel/CV is a 64-entry look-up table that sets the ratio of the moduation VCO to the audio VCO. The modulator can be lower in frequency, the same frequency, or higher in frequency. The steps begin a 0 (no modulation) to 7.375 in steps of 0.125 For example a ratio of 2.000:1 means the modulator is exactly 2X the frequncy of the audio VCO.
The MORPH mode is a selection of 32 wavetables from the E350, which are continuously morphed (blended) in the 'Z Axis' (end-to-end), The wavetables vary from sines/harmonics, vocal effects, traditional shapes to noise. The 2 outputs have the same pitch (they share the 1V/OCT input and the FM CV) but have independent wavetables. MODULATION A/MOD A set the waveshape for OUT 1 and MODULATION B/MOD B set OUT 2.
CLOUD mode is a variant of the E340 Cloud Generator, when set to the '4 Oscillator' setting. The E330 generates 4 VCOs, with OUT 1 being Sine and OUT 2 being Saw. The 4 VCOs are 'spread apart' (detuned) by MODULATION A/MOD A. This spreading is exponential, from slight beating (the 'Super-Saw effect') to a noise 'cluster'. In addition, filtered noise can be added to the spreading by MODULATION B/MOD B, which will add 'chaos' to the overall sound.
The E330 Multimode VCO raises the bar for low-cost Euro VCOs, with dual outputs and 3 operating modes, all in a small panel size.
