The 140 ENVELOPE/LFO combines an envelope generator and a low-frequency oscillator in one module, giving you both one-shot shaping and repeating modulation from a single unit. That dual function saves rack space compared to running separate envelope and LFO modules, making it a practical choice for smaller Eurorack builds. The 140 ENVELOPE/LFO covers two essential modulation jobs at once, saving rack space in smaller builds that would otherwise need separate envelope and LFO modules side by side. Features: Legendary dual envelope/LFO module from the ’80s Authentic reproduction of original “System 100M” circuitry 2 independent ADSR envelope generators controllable via external gate or manual triggering LFO features 5 waveforms: sine, triangle, square, ramp and saw tooth Frequency, delay and range controls plus external sync input for maximum LFO flexibility External trigger switch lets you phase lock the LFO to your keyboard playing 2 LFO outputs can be switched between ×1/10 or ×1 level 3 envelope outputs (2 normal, 1 inverted) 15 controls and switches give you real-time access to all important parameters Eurorack specs: 16HP, 50mA +12V, 50mA -12V
