Multi-purpose envelope/LFO modulation source that is part of the SYSTEM-500 fully analogue modular synthesizer in Eurorack format and can be mixed and matched with other modules in any combination to create the ultimate Roland modular synthesizer. This module is completely analogue and has been designed for maximum compatibility with the world of contemporary synthesizer and effects modules. It 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, it 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. The module comes supplied with four Eurorack installation screws and Eurorack power cable. Dimensions: 81 x 58 x 129 mm. Weight: 202 g.
