Ronan Fed RF-BASSLINE v1.1.1 VST VST3 WiN [FREE]

Ronan Fed RF-BASSLINE is a free monophonic bass synthesizer for Windows, aimed at producers making acid house, techno and trance. Its single-oscillator design takes inspiration from the Roland TB-303, combining a low-pass filter, distortion and slide to recreate the character of vintage analogue acid basslines.

The plugin is built around programming patterns in your DAW, making it useful for hobby producers who want to write intricate acid sequences without a hardware bass synth. Slide provides movement between notes, while velocity-to-accent handling lets note velocity influence the accented feel of a pattern. A phase start control is also included.

Available in VST and VST3 formats, RF-BASSLINE suits Windows setups running compatible hosts such as FL Studio and Ableton Live. Version 1.1.1 improves velocity-to-accent behaviour and makes minor interface adjustments. For producers looking for a focused bass instrument rather than a broad sound-design workstation, it offers a straightforward set of tools for exploring TB-303-style patterns.
