Authentic 3340 VCO, four simultaneous waveforms, FM, and more
The analog architecture of the Behringer MS-101 is built upon its authentic 3340 VCO (Voltage-controlled Oscillator) with four waveforms — all of which can be active simultaneously for seriously complex timbres. Waveforms include sawtooth, triangle, square (with PWM), and an octave-divided square sub oscillator. What’s more, the VCO can be adjusted across a broad 4-octave range. This impressive flexibility gives you the tools you need for unfettered creativity. As a bonus, the MS-101 features the “Nova Mod” that many players made to their original synths in the ’90s, adding VCF frequency modulation with six available FM sources. Between its multiple waveforms and FM, the MS-101 takes you far beyond the sonic capabilities of the original.

VCF: heart of the beast
The VCF (Voltage-controlled Filter) shapes the oscillator signal of an analog synth. The MS-101’s VCF has faders for cutoff Frequency (10Hz to 20kHz), Resonance (0 to self-oscillation), Envelope, Modulation depth, and Keyboard follow (0 to 100%). Envelope, keyboard tracking, and Bender control the MS-101’s VCF in real time. The FM Source rotary selection lets you choose Sawtooth, while the FM Amount knob controls depth. Sub Oscillator 1 or 2 octaves down, narrow or noise.
