SynthIV – Stereo Pulse Ultra x32 VST WiN

Stereo Pulse Ultra is a free VST plugin for Windows that turns volume modulation into a rhythmic stereo tool. It provides two tempo-synced pulse LFOs per channel—left and right operate independently unless you enable mix-to-mono—so you can shape timing, alignment, and volume for each side separately. Use the phase slider to align the pulse waves or set them five units apart (5 and 10) to spread pulses evenly across the stereo field. Beat division offers a wide range of rhythmic options, and you can either sync to host tempo or type in a BPM manually. Bypass switches sit above the peak meters for quick A/B checks, and a selector under the tempo controls shows or hides a built-in quick help window. At just 2 MB, it is a lightweight addition for hobby producers working in FL Studio, Ableton Live, or Logic on Windows who want to create moving stereo textures, gated rhythmic patterns, or subtle pulse effects without a complex setup.
