"Beautiful, fun and inspiringly expressive" - The Arithmophone Pentatone is a music app featuring an easy to play pentatonic keyboard and a built-in synthesizer. Instead of using piano keys or a grid-based interface, Pentatone takes a fresh approach, optimised for the ergonomics of touchscreen devices and inspired by instruments like the kora and mbira. The app also has a sophisticated scale selection system that includes all the common pentatonic scale types and unlocks some more unusual ones. Pentatone features: - An easy-to-play and 'strummable' keyboard, split for two handed playing - An original pentatonic scale system with 9 selectable scales, in just intonation or standard tuning - A custom synth engine (binaural 2x2 op FM with stereo detune, resonant filter, delay and reverb) - 25 preset sounds with macro sliders for tone and ambience - Initial touch and aftertouch response, both polyphonic - AUv3 functionality for use within host apps like GarageBand, Koala Sampler and Loopy Pro Pentatone user feedback: "Amazing! Love the simple UI and the musical keyboard. Also the sounds are lovely!" "This is very cool - beautiful interface and instantly musical." "This really is a joy to play and the tones are really expressive in fun ways that invite different types of creativity." "This app is such a brilliant idea!" "This is amazing. So fun to play. So easy to play with my daughter and my niece. The tones are wonderful." "This is an inspiringly expressive instrument! Really a joy to interact with." "This thing is AWESOME! It’s so easy to make up new stuff with it!" *** Pentatone is part of the Arithmophone project An Arithmophone is a thing that turns numbers into sounds, or math into music. Its name is derived from the ancient Greek words arithmos (number) and phone (sound). Any iPhone or iPad is itself an Arithmophone, because it routinely turns lists of binary numbers into sounds, for example when you use it to listen to music. But this app is a bit more 'arithmophonic' still, because it takes pure and simple harmonic ratios like 3:2 and 5:4 and uses these to build musical scales. You can use it as an easy-to-play instrument, a source of melodic and harmonic inspiration or a tool for learning about music and exploring the deep connection it has with numbers. Keep an eye out, future plans for the Arithmophone on iOS include: - PENTATONE JR., a simplified and text-free version of Pentatone, optimized for young/beginning musicians - DIATONE, the diatonic companion to Pentatone, featuring a 7-note-per-octave keyboard with all the familiar major and minor scales and modes - MIDI / MPE versions of Pentatone and Diatone - TONEHIVE, a microtonal keyboard synth for 7 limit just intonation - HUYGENS, a microtonal keyboard synth for 31 EDO To stay posted, join the community at reddit.com/r/arithmophone or subscribe to the Arithmophone youtube channel: https://www.youtube.com/@arithmophone

DJ Analyzer analyzes your music and helps you prepare your sets from your phone: BPM, Camelot key, energy and genre for every track, plus the tools to organize them and take them to your DJ software. LISTEN What's playing? Hold your phone near the speaker and DJ Analyzer identifies the track. If another DJ has already analyzed it, you instantly see its BPM, key, energy and genre, similar tracks and more from the same artist, and you can save it to your history. SHARED MEMORY DJ Analyzer recognizes each track by its sound, not by the file. If another DJ already has your track, even in another format or quality, you benefit from their work: the analysis is instant, the community's cue zones show on the waveform, and the BPM, key and beat grid another DJ brought in from Rekordbox, Traktor or VirtualDJ improve yours. Manual corrections only reach others when three DJs agree. TRACK ANALYSIS • BPM with double and half tempo detection, and beat grid • Key in musical notation and Camelot • Energy from 1 to 10, genre and subgenre • Track type: warm-up, peak time, closing… • Structure: intro, build-up, drop, breakdown and outro • Artwork and a 6-second preview YOUR MUSIC, WHEREVER IT IS Add tracks from your iPhone or from iCloud, Dropbox, Google Drive or OneDrive. Import your Rekordbox or Traktor collection, or your Apple Music library data. And if your music lives on your computer, link it with a code and your library shows up here, with its folders, sessions, cues and ratings. FULL-SCREEN WAVEFORM Turn your phone sideways and the waveform fills the screen: pinch to zoom, cues snapped to the beat or the bar, Tap BPM, beat grid adjustment and the community's zones. SESSIONS Build your sets on your phone: every transition with its quality and a tip for mixing it, the set's energy curve, and Smart Suggest to find the next track. Sort them by energy, harmony or BPM, export them to Rekordbox (XML), Traktor (NML), M3U or CSV, and send them to your Mac over AirDrop. ORGANIZE • Camelot wheel with the tracks in each key and their compatible keys • Smart Collections that fill themselves with rules for BPM, key, energy, genre and track type • Folders, favorites, filters and stats for your library DJ Analyzer doesn't replace your DJ software: it gets everything ready for it.
