Fuzz Droid is a distortion effect based on the gain stage in the CP3 modular mixer. A sharp, asymmetric discontinuity generates massive harmonics and makes for a hyper-aggressive sound. It's the rudest effect we've ever made. Crunch It! - Two asymmetric distortion circuits from the OG CP3 module - CP3+: a sharp discontinuity for big harmonics, absolutely brutal on synth drums - CP3-: smooth and heavy, for when the positive curve is too rude - Drive up to +48 dB Digital Extras - Custom smoothing function tames harsh artifacts - Bias control shifts how you hit the asymmetry - Flexible high-pass and low-pass tone-shaping filters - Pre or post filter placement Core Features - Morph Settings for smooth transitions between two complete configurations - Auto Bypass saves CPU when input is silent - AB settings comparison - HQ mode with 4x oversampling and ADAA - One-click loudness matching - All parameters automatable with precise playback - Light and dark interface modes - Internal undo/redo - Auto gain - Standalone app includes support, manual links and in-app purchase options for license purchase Two-week trial included, one-time purchase for full unlock.

About

SpinBud

Features
Read full description

SpinBud is a rotary spatial modulation effect for iPhone and iPad. It is built around a simple scene: your sound drives up to 3 rotating speaker plates, each plate can hold up to 3 horns, and a fixed stereo mic rig captures the movement. Use SpinBud on organs, synths, guitars, pads, drums, vocals, or full mixes when you want moving stereo color, gentle cabinet bloom, tempo-synced tremolo, wide chorus-like motion, or unstable broken-speaker textures. ROTARY PLATES - Use up to 3 independent rotating plates - Set each plate's speed, direction, horn count, level, phase, and band range - Choose free-running speed in Hz or sync plate motion to host tempo - Shape speed changes with Ramp Up and Ramp Down - Drag plates directly in the visualizer for manual spin gestures SPLIT-BAND MOTION - Send different frequency ranges to different plates - Start quickly with band presets such as Low, Body, Mid, Presence, Air, Full, and more - Adjust custom Min Freq and Max Freq values per plate - Use the spectrum view while finding useful band ranges - Keep low movement slow and high movement fast, or overlap bands for denser modulation STEREO MIC RIG - Capture the rotating plates through one shared stereo mic setup - Adjust mic angle and stereo spread - Set left and right mic distance independently - Blend dry and wet on the main output - Add Room for a small cabinet-style space around the wet signal ROTARY CHARACTER - Add Doppler for pitch movement from approaching and receding horns - Use Directivity to control how focused the horn movement feels - Increase Tone to darken horns as they turn away from the microphones - Add Wobble for motor drift, loose movement, or broken rotation - Push the excitation path with Drive PRESETS AND ROUTING - Load factory presets for chorale, tremolo, brake, wide, chorus, wobble, shimmer, lo-fi, and multi-plate setups - Save your own user presets - Run as a standalone app - Connect MIDI in standalone mode and use MIDI notes to flick individual plates - Use AUv3 multi-out in compatible hosts to route separate wet stereo stems for Plate 1, Plate 2, and Plate 3 SpinBud is not a full Leslie simulator. It is a rotating emitter plus fixed stereo listener effect for motion, width, rhythmic modulation, and split-band rotary sound design. The AUv3 FX plugin needs a compatible AUv3 host such as AUM, Logic Pro for iPad, Loopy Pro, Cubasis, GarageBand, BeatMaker 3, or another compatible host.

Verdict

The call
