From the US Store: Songwriter's pre-production tool extraordinaire ! ***** by Mythmongrel - Version - 1.2.0 - Oct 31, 2014 The best app for easily laying out the form of a composition. It's does exactly what it's meant to do and it keeps getting better. Highly recommend it. Accept No Substitutes. ***** by Focusking - Version - 1.2.0 - Oct 9, 2014 Get this app, and you are in for a pleasant surprise; it's versatile, it's multi-purpose, and it knocks the competition out of the game. And, unlike other developers, this dev responds promptly, and positively. Are you a songwriter, electronic composer or are you in a band? Do you record your music and sometimes have trouble getting started or laying down tracks to record on top of? If the answer to either of these questions is yes then you owe it to yourself to own Guide Track! Guide Track is the primary go-to tool when you want to quickly create a precise guide track for recording when you know the song structure and the style. Simply enter in the time signature (which you can change at any time during the song), which chords (or rests) for how many beats and the beat style—Guide Track does the rest for you! Use inter-app audio or AudioBus 2 or save your track to file and you are ready to start recording for real with a perfect smart click track and guide chords, drums and bass. Save hours of messing around and get to what matters—your creativity. Once done you can mute the guide track to reveal your perfectly structured recording. It's like a sculptor using a mold when casting, except instead of bronze, you end up with perfectly structured music. You may want to even keep your guide track in there or record one of the parts such as bass or arpeggios as a real track, especially if you use a professional synth via MIDI out. You can also use Guide Track to print out chord sheets for your band or to capture song ideas or for recording aid.

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.
