The Roland System-100M 140 module is a versatile component of the System-100M modular synthesizer, combining two ADSR (Attack, Decay, Sustain, Release) envelope generators with a low-frequency oscillator (LFO). This module is essential for shaping the dynamics and modulation of synthesized sounds, providing precise control over amplitude and filter contours, as well as offering modulation sources for various parameters within the modular system.

Features

• Dual ADSR Envelope Generators: Each envelope generator can be triggered by gate, gate plus trigger, an external gate, or manually via a momentary switch. They offer two positive outputs and one inverted output per envelope, allowing for flexible routing and modulation possibilities.
• Low-Frequency Oscillator (LFO): The integrated LFO operates within a range of 0.05 Hz to 30 Hz and provides five selectable waveforms: sine, triangle, square, sawtooth, and reverse sawtooth. It features broad frequency range selection (low, medium, high) and fine frequency control, along with a delay function. The LFO can be synchronized to the cabinet keyboard trigger and includes an input for external control voltage modulation of its frequency. It offers two outputs with adjustable output levels.

Applications
The 140 module is fundamental in crafting dynamic and evolving sounds within the System-100M setup. The dual envelope generators are crucial for articulating the amplitude and timbral changes of sounds, while the LFO serves as a versatile modulation source for parameters such as pitch, filter cutoff, and pulse width modulation. This combination allows for the creation of complex, animated textures and rhythmic modulations, enhancing the expressive capabilities of the synthesizer.

Country of Manufacture
Japan.

Collectability and Market Value
As a key module in the Roland System-100M series, the 140 Dual Envelope / LFO is highly regarded among synthesizer enthusiasts and collectors. Its comprehensive feature set and integral role in sound design contribute to its desirability. The market value of this module reflects its importance within the System-100M ecosystem and its enduring appeal to those seeking authentic analog modular synthesis experiences.
