DOEPFER / A-111-5 Mini Synthesizer Voice

Variations

Modular version of Dark Energy.

Similar to the world's best-selling analog synthesizer MS-404, the MS-404 consists of 1 VCO, 1 VCF, 1 VCA, 2 LFOs, and 1 ADSR, but each section has enhanced functions. Oscillator waveforms can be selected and mixed from three waveforms: triangle wave, sawtooth wave, and pulse wave. Pitch can be modulated by LFO1/ADSR and pulse width by dedicated knobs (manual)/LFO2/ADSR respectively. The filter is a self-oscillating low-pass filter with 24dB/oct. The cutoff frequency can be modulated linearly or exponentially with LFO2/ADSR, allowing the MS-404 to reproduce its signature metallic sound. LFO1&2 oscillate up to 5KHz with range switching, and ADSR also has a 3-step range switch to function as a powerful modulation source.
