Echo Pitch vs Robot Butter

Echo Pitch pitch-shifting multi-delay for iPad and iPhone! Echo Pitch has 4 delays where each delayed signal can be pitched one octave up or down in 1/2 steps, and can function as a 4-voice harmonizer. Echo Pitch also has a built-in freeze loop, amp simulator and reverb. Each of the four delays can be routed into the other for incredible, swirling, ambient washes and otherworldly sounds. Echo Pitch works best with an iOS-compatible audio interface. Echo Pitch is also AUM/Audiobus compatible - as Inter-App Audio or Audio Unit. (Please note that the standalone/IAA version of Echo Pitch is now legacy. While the AU Echo Pitch has the same functionality, the pitch shifting is far superior. In addition, there are sonic differences between the Reverb, Master Delay EQ, Delay drives in the AU vs the Standalong/IAA version. But you get both updated AU and legacy IAA. Use whichever you prefer!) Brought to you by Avi Bortnick and Maximos Kaliakatsos-Papakostas.

Robot Butter is a creative AUv3 audio effect for compatible hosts on iOS & iPadOS. It blends animated modulation, adaptive reverb, tempo-aware movement, and digital texture into one fast, playable interface. At the core is the Robot engine, where Actuator, Viscosity, and Controller create the main motion and character of the signal. That signal then feeds Butter, an adaptive reverb stage designed to intelligently stay musical while responding to the effective movement of the Robot section. The result can move from focused width and pulse to washed ambience, strange motion, and unstable experimental color. The Chipset section extends the sound with a built-in assignable LFO matrix and a post-reverb System Bus reduction stage. Run the LFO freely in Hz or lock it to musical divisions for host-synced movement, then route it to key Robot or Butter controls for evolving motion. Add System Bus for subtle grain or push it harder for sharper, crushed digital edge. Robot Butter is designed to stay immediate. The interface gives you direct control over modulation, blend, depth, reverb shape, output mix, and motion timing without pushing you into a complicated modulation environment. A built-in user manual inside the standalone app includes overview pages, parameter explanations, quick-start guidance, glossary entries, MIDI notes, and troubleshooting help, with scrollable section pills that keep longer labels readable. Factory presets and user presets make it easy to jump from polished mix enhancement to stylized movement and aggressive sound design. Features: - Robot modulation engine with Actuator, Viscosity, Controller, and gain staging - Butter adaptive reverb with Churn, Emulsion, and Culture controls - Built-in LFO matrix with free or tempo-synced timing - Assignable LFO destinations across Robot and Butter parameters - System Bus sample-rate reduction stage for animated digital texture - Imaging modes including Mono, Wide, Ping, and Drift when stereo processing is available - Factory presets covering vocals, guitars, bass, keys, synths, drums, utility, and experimental categories - User preset save, recall, and delete support - Comprehensive built-in in-app user manual with quick-start, glossary, and troubleshooting sections - MIDI Learn, Host Learn support, and default CC mappings for hands-on control - Optional MIDI CC broadcast for compatible host-routing workflows - Host tempo sync with straight, dotted, and triplet divisions Use Robot Butter for vocal movement, guitar widening, synth pulse, drum bus animation, ambient wash design, or aggressive lo-fi modulation chains. It is built to move quickly from musical enhancement to animated destruction while keeping the workflow focused and playable.
