With its 10 oscillators, the Levitation OSC produces spherical sounds and beats, down to the very deepest sub-basses.
Sine and sawtooth are available as waveforms in a wide frequency range. In addition to additive synthesis, there are optional noisio-typical 8-bit register overflows for chaotic sound calculation. Beside of this you can play with simple FM synthesis and a one button random chime generator. A signal to the Trigger In or pressing the corresponding button will act as a gate.
The new version of the Levitation Oscillator (v2) offers a housing entirely made of PCBs and the option of powering the device with USB-C. Also there is now the possibility to choose between normal and ducking gate mode.

This video made for version 1 gives a comprehensive overview of the functions and sounds:
