Rawoltage RW W77 v1.0

Rawoltage RW W77 is a 64-bit Windows VST synthesizer modeled on a 1977 Wersi Bass synth. Designed for monophonic bass lines and leads, it brings the character of the original hardware into a software instrument with a few additional sound-shaping options. It suits hobby producers who want vintage synth tones without navigating a complex synthesis engine.

The core includes three waveforms, bass guitar emulation, attack and decay controls, and an automatic LFO that can also modulate the filter. Auto-wah adds another way to shape the movement of a bass part or lead phrase.

A separate Modification panel extends the hardware-inspired design. You can introduce simulated potentiometer noise, amplifier buzz, and oscillator faults for a less pristine sound. The expanded controls also offer a deeper filter cut than the original unit, LFO synchronization, and a simulated stereo effect.

For producers using compatible Windows VST hosts such as FL Studio or Ableton Live, RW W77 offers a focused approach to retro bass and lead programming.
