Module in Eurorack format

Dual Envelope Generator & LFO (Low Frequency Oscillator) is a multifunctional modulation source Two independent ADSR envelope sections (Attack, Decay, Sustain, Release) can generate different voltages to control other synthesizer modules in Eurorack format (e.g. oscillators, filters and VCAs) Each section can be triggered in different ways: via an external source, internally, manually via the connections for each of the envelopes or via an inverted output signal
