Roland 2ENV/LFO 540 Modulært system

Add precise modulation control to your Eurorack setup with the SYSTEM-500 540, a fully analog dual envelope generator and LFO module rooted in the design legacy of Roland's classic SYSTEM-100M modular synthesizer.

Two independent ADSR envelope sections produce variable control voltages for shaping oscillators, filters, VCAs, and other Eurorack modules. Each section can be triggered externally, internally, or manually via dedicated gate inputs, and includes an inverted output for expanded modulation possibilities.

The onboard low frequency oscillator offers five simultaneous waveform outputs — square, triangle, sawtooth, inverted sawtooth, and sine. Front panel controls adjust frequency and delay time, with delay and reset triggerable from either envelope section.

Designed to pair with other SYSTEM-500 modules, the 540 fits the standard Eurorack format at 16 HP wide and is fully compatible with third-party Eurorack systems. Top-quality components and solid build reflect a collaborative production process between the USA and Japan.
