"EMW WCS-1x Digital/Analog hybrid monosynth in excellent cosmetic and fully functional condition. I bought this after hearing it at a trade show. The multimode filter sounds amazing, super punchy and does incredible bass sounds, but also strange SH-03 style timbers.
The WCS-1x uses a DSP-based "Wave Composition Oscillator". The WCO's toggle switches allow you to access several waveshapes ( -including a fundamental square, a sub-octave, an "acid ring" waveform -which adds an aggressive edge to your sound, a sawtooth as well as a square wave -routed through either a bandpass or low pass filter -depending upon their respective toggle's position ). The WCO's toggle switches also allow you to select various octave settings ( +1 Octave, +3 Octaves or the fundamental's ). The LFO wave toggle allows you to select either a triangle or square wave for modulation purposes. At the top left corner of the WCO section is a MIDI channel button ( -with a "Gate" and "Learn" LED ). Next to it, you'll find a glide + and - ( portamento ) toggle switch. An unconventional arrangement but it works once you get used to it.
The remainder of the WCS-1x's controls are more straight forward knobs. You get one each for filter cut-off, filter resonance, filter envelope modulation, filter LFO modulation ( amount ) with the last knob to the right controlling the LFO's frequency. Below the filter section you'll find four knobs for controlling VCA attack, decay, sustain and release envelope segments. The knobs have a smooth, rock solid feel as you turn them."
