As a part of the Roland System-500 system, there's great flexibility and power within this module. With a high quality build and a surprisingly affordable price point, the System-500 modules make a great addition or centerpiece for any modular system.

Roland System-500 540 Modular 2 Envelope LFO is an outstanding multi-use modulation source. The System-500 540 boasts two seperate ADSR envelope sections to produce variable voltages for use with other Eurorack systems, sych as a filter, VCA, or oscillator. The different sections are capable of being triggered in three ways - externally, internally, or manually - with unique jacks for each envelope, as well as having an inverted output. The 540 also features a VC LFO with five waveform outputs.
