The PUC is a wireless MIDI interface designed specifically for iOS devices. PUC Connect is the app designed to establish your iPad/iPhone connection to the PUC hardware. PUC Connect also monitors your PUC hardware for battery status, firmware updates, and connection protocol selection. If you have a MIDI keyboard controller, home digital piano, synthesizer, or computer controller, connect it to the PUC and play your musical instrument apps from your favorite MIDI controllers. The PUC allows you to wirelessly connect an iPad, iPhone or Mac to a variety of MIDI compatible devices such as a keyboard, DJ controller, drum pad, floor pedal controller, and more. The PUC can also work with other platforms that support MIDI connections over Bluetooth wireless. The PUC communicates directly to the iPad, iPhone, or Mac via Bluetooth Smart (Low-Energy 4.0) You have an iPad loaded with amazing synthesizer & music creation apps, but connecting your controller creates a tangled mess and no longer makes you mobile. The PUC and the PUC Connect app makes MIDI connectivity easy so you can get on with your business – making music. PUC also connects to your Mac for wireless CoreMIDI control.

  • Four distortion algorithms (Saturation, BitCrush, Ring Modulation, Downsampling)
  • Intuitive XY pad for blending effects
  • Custom waveshaping saturation
  • BitWarp for tonal variation
  • Tunable oscillator for ring modulation
  • Adjustable downsampling rate and jitter
  • AUv3 audio effect plugin

Four complementary distortion algorithms — Saturation, BitCrush, Ring Modulation, and Downsampling — blended and shaped through an intuitive XY pad. Saturation Shape harmonics using Quantum Distortion’s custom waveshaping saturation. Adjust Drive to set the intensity from subtle warmth to strong coloration, and use Asymmetry to introduce controlled even-harmonic emphasis of vintage tube characteristics. BitCrush Reduce digital resolution using BitCrush and reshape the crushed signal with BitWarp, which bends the quantization curve for additional tonal variation. This combination allows precise control over both the amount of reduction and the character of the resulting digital artifacts. Ring Modulation Introduce inharmonic motion using ring modulation, generated by multiplying the input with a tunable oscillator. Adjust frequency and amount in real time to create anything from light metallic shading to dense, shifting sidebands. Downsampling Lower the sample rate using Downsampling, reducing temporal resolution for classic digital degradation effects. Set the rate down to 200 Hz or introduce Jitter for controlled randomness, adding instability and movement to the downsampled signal. XY Pad Blending Navigate between the four distortion algorithms using the XY pad, allowing smooth transitions or static blends across the processing modes. The background updates to reflect the current region, providing clear visual feedback while exploring hybrid distortion shapes and interactions. Quantum Distortion is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
