Roland System-500 540 ENV / LFO
Roland System-500 540 Dual Envelope Generator + LFO
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.
