Roland System-500 Eurorack Dual Envelope Generator and LFO Module
Bonus Item

Roland 540 Dual Envelope Generator and LFO is a multi-purpose modulation source. This unit features two independent ADSR (attack, decay, sustain, release) envelope sections that produce variable voltages for controlling other eurorack format synthesizer modules such as oscillators, filters and VCAs. Each section can be triggered externally, internally or manually with dedicated jacks for each envelope as well as an inverted output.

Additionally, 540 includes a voltage-controlled LFO with 5 waveform outputs. Front panel controls adjust both frequency and delay time of the LFO start. Delay and reset can be triggered from either envelope 1 or 2.
