Product Description

The System-500 Series - 540 from Roland is a dual voltage-controlled envelope and a single low-frequency oscillator (LFO) in a single Eurorack module. Each independent envelope offers parameter slider for attack, decay, sustain, and release (ADSR) and includes two standard outputs and one inverse output. Additionally, the envelopes have a manual-trigger switch, a fast/slow envelope-speed switch, and a gate-trigger switch that selects whether the envelope is triggered externally/manually or cycles, which creates a self-cycle based on attack and decay settings.The LFO offers knob controls for selecting the frequency and delay, while the CV Freq input allows for voltage control over the frequency of the LFO. Additionally, the LFO offers the simultaneous outputs of five waveforms, including square, triangle, sawtooth, reverse sawtooth, and sine. The Freq Range offers a three-way switch for selecting high-, medium-, and low-frequency ranges, while the Keyboard-Trigger switch offers settings for resetting the LFO waveform by envelope 1 or 2. The Delay Trigger also resets the LFO delay by envelope 1 or 2. The 540 ships with four rack screws and a ribbon cable to connect to an optional Eurorack modular power supply.
