The magic to the chorus sound in the Dyno My Roto is three LFOs, giving you lush modulations singing out like a chorus of guitars. Most chorus pedals are simply two voice, one straight and one modulated. This offers twice the amount of joy by modulating another voice. That significantly reducing the ability to just hear one voice being affected and smears a couple voices in an effect that is truly enjoyable to listen to.
Keeley came up with a new Proximity Control Rotary Cabinet package that gives you a Proximity Contro. The Proximity Control controls how far away you are from the spinning speaker cabinet. This adds a depth and distance to the cabinet and is a touch like a reverb control. The spatial expanse can give you presence or depth in the chorus-like rotations. Lastly, while we were spinning things, they crafted a RotoFlange sound that has a simple negative feedback control. Easy to use and gets you the most classic flanger sounds possible.
