Pianoscaper is a generative music app and virtual instrument that’s easy on the ears and fun to play. Launch the app, and with a single tap of the auto-play button, pianoscaper will create evolving and ambient soundscapes that are unique every time. While all of the pianoscaper sounds originated from acoustic pianos, many have been extensively processed to create an “impossible piano” that can morph between orchestral-type swells and ethereal choir-like sounds. Think of it as piano DNA taken to the next level! Pianoscaper in auto-play mode is the perfect companion for relaxing, studying or providing non-intrusive headphone music at work or on your commute. You can even set a timer so you can fall asleep to its gentle and soothing tones. You can also play pianoscaper as a virtual instrument using the dedicated keypads and performance loop recorders, and tailor the sounds with built-in reverb, delay and “character” effects parameters. And while you’re playing, pianoscaper can lend a hand by adding auto-accompaniment parts and even provides hints for notes it thinks might sound good depending on which notes you play! As a sample-based instrument, pianoscaper currently supports two “moods” – a happy mood, based on the G major pentatonic scale, and a sad mood, based on the Dm pentatonic scale. Please note that pianoscaper is not a chromatic or MIDI-compatible instrument, and it is unlikely to become one, although additional moods and scales may be added as free updates. You can also record and process the audio output of pianoscaper using any Inter-App Audio host that supports IAA Generators. You are free to use pianoscaper in your own recordings or live events and installations on a royalty-free basis. All I would ask for is a simple credit that includes the name of the app – “pianoscaper”. I hope you will agree the pianoscaper interface, while minimalist and a perhaps a little cryptic initially, will eventually become very easy to use. Please do take the time to read the quick-start guide which can be found on the website. This is also the best place to ask questions, get technical support or report any issues. Happy pianoscaping! *** Please note that this app is now in maintenance / bug fixes only mode as it relies on "deprecated" (by Apple) technology such as IAA. ***

Otoo is a streamlined, one-screen groovebox designed for frictionless music production. Built around an innovative free-form step sequencer, Otoo breaks away from rigid grids, allowing you to place, drag, and stack notes freely across independent rows. Whether you are sketching out ideas using the native built-in engine and sampler or hosting your favorite third-party AUv3 plugins, Otoo delivers a distraction-free environment that prioritizes speed and musical flow. On iPhone, the interface dynamically scales to give your AUv3 instruments a near-fullscreen home, paired with a compact, highly responsive keyboard for immediate creation on the go. Otoo also includes Otoo MIDI, an AUv3 MIDI processor version of the app. It brings Otoo’s pattern-based sequencing into compatible AUv3 hosts, where playback follows the host timeline and instruments are routed as MIDI Out destinations instead of audio instruments.
