SoliderSound has released S Pulsar, a freeware mid-side modulation plugin that adds and changes the rhythm of your sounds and tracks.

S Pulsar utilises a square LFO to apply a pulsing tremolo effect to your input signal. Then you can adjust the timing of the pulses, apply mid/side processing, and more!

SoliderSound – S Pulsar

S Pulsar offers a small number of tools for adjusting how the effect manipulates your sound in real time.

In practice, the mid-side slider found in the bottom-middle of the S Pulsar plugin lets you specify the part of the signal that you want to modulate. Load an expansive stereo sound and use the slider to determine whether the plugin modulates the sides or the centre!

Additionally, you can choose from ten pulse rates (from 1/1 to 1/32). You can also use onboard controls to mute your signal before gradually bringing it back to its original level with modulation applied.

Further, you can adjust the depth of the effect and dial in the intensity as you see fit, while the built-in on/off switch allows you to automate the processing. The plugin allows you to offset the effect too by adding a delay before the plugin kicks in, which SoliderSound states, “lets you decide whether you want the transients of the audio to remain audible”.

Finally, you can resize the GUI from 80% to 150% to accommodate smaller and larger screens.

Ultimately, SoliderSound’s Pulse R plugin is a fantastic option for adding rhythm and transforming your tracks. Whether you want to apply the effect to a lead synth melody, create some intriguing sound effects, or add a new character to your chord progressions, Pulse R gives you plenty of options to do these and more.

You can get the Pulse R plugin now as a free download, and it’s compatible with Windows and macOS in VST2, VST3, and AU plugin formats. Finally, the plugin supports both 32-bit and 64-bit host software.
