    Product Description

    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.

    Dual Envelope Generator + LFO
    Based on the legendary SYSTEM-700 and SYSTEM-100M, the SYSTEM-500 introduces a range of fully analog Eurorack modules inspired by two of the most revered electronic instruments of all time. They include classic Roland oscillators, filters, envelopes and effects that can easily integrate into any existing Eurorack setup or form the centerpiece of a new modular system.

    Designed and built in the USA, each SYSTEM-500 module is made to exacting standards with top-quality components and extreme attention to detail. They sound as good as they look with classic character and modern reliability. And they're surprisingly affordable, turning the fantasy of finally owning a Roland modular synthesizer 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. 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.
