Vermona Mono Lancet '15 Desktop Monophonic Analog Synthesizer Module

Vermona Mono Lancet '15 is a compact synthesizer with a big sound, an uncomplicated user interface and lots of charm. The original Mono Lancet was an instant classic, and the '15 update adds three extra LFO waveforms and a USB port for firmware updates.

Two analog oscillators ensure a solid sound foundation. Oscillator one creates triangle, sawtooth and square waves and has a range one octave lower than the second oscillator. The latter has the same sawtooth and square waves but replaces the triangle with a white noise source. The pulse width can be modulated over MIDI via the modulation wheel. The glide generator has a legato mode or can be permanently engaged.

The voltage controlled lowpass filter has a slope of 24db per octave. On high resonance settings it self-oscillates, producing a stable sine wave that can be played over a range of about 2½ octaves. Using MIDI, the cutoff frequency can be set to respond to velocity and/or aftertouch.

There's a strong VCA inside Mono Lancet '15 that can be modulated by the ADSR envelope generator or a fixed, 'organ-like' envelope. It can also be switched via MIDI CC to respond to velocity.

The ADSR envelope generator can modulate the VCO and VCF frequency as well as the VCA. The LFO offers saw up, saw down, sine, rectangle and triangle waveforms as well as sample & hold and can be a modulation source for the VCF and/or VCO.

There's a 25-pin D-sub 'extension' connector on the rear of Mono Lancet '15. The optional Mono Lancet Modular Dock (sold separately) is a eurorack module that widens the potential of the synthesizer enormously through numerous inputs and outputs for control voltages and audio signals, per-oscillator PWM and filter cutoff inputs being just two examples.
