540 Dual Envelope Generator + LFO Eurorack Module

The 540 Dual Envelope Generator and LFO (low frequency oscillator) 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, the 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.

Classic System. New Format.

The SYSTEM-500 consists of Eurorack format modules that you can mix and match in any combination to create the ultimate Roland modular synthesizer. Each module is completely analog and has been designed for maximum compatibility with the world of contemporary synthesizer and effects modules. The SYSTEM-500 is a compact, powerful system that opens up vast possibilities for sound design and musical exploration.
