Notation vs Arc & Decay

Notation is professional sheet music notation for composers, arrangers, and music students. Capture a motif at the piano, tweak harmony on your commute, or share a link before rehearsal—all on iPhone or iPad with lyrics and chords. If you read a staff, you can go from a piano sketch to multi-staff scores for class and rehearsal. TOUCH NOTATION A notation keyboard replaces deep menus: tap notes and markings, or select on the staff to edit. Undo/redo for commutes, rehearsal gaps, or at the piano. On the free tier, inserting or editing measures shifts later bars automatically so the rest of the score stays aligned. WRITE AND HEAR IT Multi-staff playback; on long scores, playback follows your edit position. Composer Pro: per-staff Mute and Solo for full scores. WEB SCORE SHARING Generate a web score link—text or email to teachers, singers, or collaborators. Any browser shows standard notation and multi-part playback without installing the app. Print-friendly pages for handouts. PDF for archives and fixed layout; web links when your choir or band needs to hear the piece before rehearsal. Many mobile apps stop at PDF or screenshots; Notation shares playable web scores with the same playback and layout as on your device. EXPORT AND INTERCHANGE MusicXML, MIDI, PDF (screen preview + A4 print PDF). Import MusicXML without length limits—continue in MuseScore, Sibelius, etc. Free tier: starter export allowance. Composer Pro: unlimited export, clean PDF (see app for web-link limits). IPAD PRO WORKSPACE On iPad, library and score sit side by side for desktop-like sessions. iPhone: full notation and sharing when you are catching ideas on the go. YOU CAN ALSO: - Piano keyboard chord stacks; multi-verse lyrics with melismas and paste lyrics line by line; measure insert/copy/paste/delete - Ties, slurs, manual beams—free - Cloud sync (web links need sign-in + sync); Composer Pro: 8 staves, 2 voices per staff, transpose, meter changes NOTATION COVERAGE: * Notes/rests, dots, ties, slurs, beams (manual break/join) * Triplets; quintuplets–septuplets (Composer Pro) * Ornaments, articulations, dynamics, hairpins * Lyrics (verses), chords; title/composer/lyricist header * Clefs, time, tempo; major/minor keys; accidentals * Repeats, voltas, D.S./D.C.; pickups; measure-level edits * Templates: piano grand, treble/bass single staff, custom; long-score paging SUBSCRIPTION & LEGAL (COMPOSER PRO — OPTIONAL) Notation offers an optional paid membership called Composer Pro.

Arc & Decay is a plasma arc distortion instrument for iOS, built on the physics of real xenon gas tube breakdown. Feed it any sound through the built-in microphone and it fires an electrical arc when your signal crosses the ionization threshold. The arc saturates and distorts with odd harmonics, crackles through marginal-zone sputter, and holds a long ionization tail that decays into electrical noise long after your sound stops. Six precision encoders control every dimension of the arc character: Voltage drives the current into the gap. Ignition sets the threshold. Instability introduces chaos and arc wander. Fizzle and Spark shape the crackle density and tail length. Mix blends dry signal with pure arc output. Reverb and delay extend the electrical space without losing the character. Record up to one minute of output and share directly from the app. Arc & Decay is not a guitar pedal. It is not a synthesizer. It is a plasma arc instrument that runs on whatever sound you give it. © 2026 Synthetic Pulse Industries.
