The Envelope Please

The 140 DUAL ENVELOPE/LFO features 2 independent ADSR envelope generators that can be controlled via an external gate or manual triggering. Each envelope generator comes with a Manual Gate that you can press and hold to start the envelope cycle; independent Attack, Decay, Sustain and Release controls to adjust the rate of these parameters and 3.5 mm envelope outputs that allow you to send up to two positive waveforms out to two modules and one negative waveform.


The LFO on the 140 comes with 5 waveforms: sine, triangle, square, ramp, and sawtooth. The Frequency Range switch which sets the oscillating frequency of the LFO along with the Frequency and Delay sliders gives the 140 unparalleled flexibility when it comes to shaping LFO’s. You can also connect an external trigger switch which can work with the Delay control to phase lock the LFO to your keyboard playing.

Eurorack Ready

Installing the 140 DUAL ENVELOPE/LFO is designed to fit into a standard Eurorack case. Just connect the power cables to the power supply and screw in the module using the included screws. This allows for the 140 to be mixed with other synth modules for a truly unique set up.
