ROTOSPHERE PLUGIN

Classic rotary swirl meets rich tube warmth with effortless speed control. Modeled after the Hughes & Kettner Rotosphere 2 in detail by Nembrini Audio, this plugin captures the lush movement, musical saturation, and unmistakable character of the original Hughes & Kettner hardware: Ready for your DAW!

Built for guitar, organ, and keyboards including synthesizers and e-pianos such as the legendary Rhodes®, the Rotosphere Plugin delivers the sound and dynamics of the real rotary pedal in a compact, easy-to-use processor.

Independent low- (LF drum) and high-frequency (HF horn) rotor sections let you move from slow, syrupy churn to fast, vocal-like spin; set speeds in Hz or tempo-sync them to your session. Hit Breaker to stop rotor motion while keeping the glowing tube color for dramatic holds and ambient swells. Choose Guitar or Keyboard input voicings for instant, instrument-correct response, then open up a true stereo image that sits beautifully in a mix.

Why it feels like the real thing

A classic rotary cab pairs a fast upper horn with a slower bass rotor, spinning in opposite directions. That complex motion creates Doppler shift, phase modulation, room reflections, and alternating frequency damping—the signature Leslie®-style sound. Add a tube amp stage, and you get the coveted Hammond® drive and compression: soft, musical distortion that blooms with dynamics.

The Tube Rotosphere honors that recipe with advanced tube-saturation modeling and a Breaker for power-down stops—so your Rhodes® parts, organ lines, synth pads, and guitar tones all take on that legendary motion.
