Roland System 540

The 540 Dual Envelope Generator&LFO (Low Frequency Oscillator) is a multifunctional modulation source. It has two independent ADSR waveform sections (Attack, Decay, Sustain, Release) which can generate different voltages to control other synthesizer modules in Eurorack format (e. g. oscillators, filters and VCAs).

Each of these sections can be triggered in different ways: via an external source, internally, manually via the connectors for each of the envelopes, or via an inverted output signal. In addition, the Module 540 has a voltage-controlled LFO with 5 waveforms.

The frequency and the delay time of the LFO start point can be set via the operating controls. The delay and reset can be triggered either from Envelope 1 or Envelope 2.

Features Roland System 540

• eurorackformat module
• 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.
