Two independent ADSR envelope sections in a Eurorack-compatible 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.

Based on the classic SYSTEM-100m modular synthesizer, the SYSTEM-500 is a fully analog recreation of one of the most revered electronic instruments of all time. Newly designed in Eurorack format, the SYSTEM-500 delivers the classic character and functionality of the original with the advantages of a modern instrument. Built in the USA and assembled in Japan, the SYSTEM-500 is made to exacting standards with top-quality components and solid controls. And it’s surprisingly affordable, turning the fantasy of finally owning this legendary instrument into reality.

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.
