Deftaudio is at it once more! We not too long ago lined their fidget spinner Eurorack module, and now they’ve turned the idea on its head! A highly effective stepper motor inside this module has a shaft coupler hooked up to it, so you may get artistic and use it to show knobs routinely on some other module in your rack. Or you may use it as a show piece, and have it spin an LED board in response to the music you’re making.

The MotorPot will be managed through MIDI by the usual Eurorack TRS-A/B cables or through USB as a MIDI class system. It’s additionally doable to rotate it with a management and gate voltage like conventional analog synthesizers usually use.

The instance proven above may be very over-the-top and we expect it’s nice! Controlling a linear potentiometer with a reciprocating drive is simply ridiculous sufficient to be superior. The actual stepper motor used has some energy behind it, and Deftaudio recommends giving it a separate 2A provide if it’s going for use in a manner that attracts a number of energy. Most Eurorack energy provides should not fairly beefy sufficient to deal with the load that this module creates, so double-check what your rack has earlier than set up.

The module is out there each as a DIY package and as a completely assembled unit, able to go. If constructing the DIY possibility, make certain to get a Teensy 4.0, both from Deftaudio pre-programmed or from one other vendor after which program it your self. Give your rack some character with this quirky motorized module!
