Creativity and AI Support in Contrast: ------------- A Study Project ------------------- Is it possible to create an app and use AI for the entire programming process, including concept and artwork? The result should be an iOS app that deals with piano chords. It has to be built using SwiftUI without requiring any prior SwiftUI knowledge, no use of custom source code or other libraries. The result is here for free in the App Store and my personal impressions after completing this project: It's a perfect way to learn SwiftUI, but you have let AI explain any source code you don't fully understand. You definitely need to know how to ask the right questions and existing knowledge of Apple iOS programming is necessary. Regular backups before making elementar changes are essential, but finally most of the app was created using AI. Notes entered across two octaves searched and matching chords are shown. There are exact matches and which other chords the notes appear in. A chord library displays 400 chord types and can show all inversions. Three piano Sound Modules are available for playback and can be played directly or as an arpeggio. Each chord can be added to one of 16 favorite lists. Landscape, Portrait, Dark Mode, and color schemes are supported. - Chord search across two octaves - Precise chord names including inversions - Display of chords containing the notes - Chord library with 400 types and a total of 1700 chords - Selection by root note and filter by number of notes - Chord player with details and playback - Player with three piano types and arpeggio mode - Adjustable player octave and arpeggio delay - Custom reverb effect for output - 16 favorite lists where a chord can be added to the player

OnScore is a music stand for musicians: import your scores, mark them up, order them into setlists, and perform straight through. Metronome, tuner, tempo trainer and recorder are built in. Bring your music in as PDF or MusicXML, photograph paper with the camera, or search free public domain scores. Then read it, mark it up, practise it and perform from it, all in one place. READING Page turns that keep up with you. Tap the edge of the page, swipe, or use a Bluetooth pedal. Choose the layout that suits the music: single page, two page spread, half page so there is no gap at the turn, continuous scroll, or reflow, which re-engraves a structured score to fit your screen. HANDS FREE Turn pages with a glance. Wink, turn your head, nod, raise an eyebrow or open your mouth. You choose the gesture and how sensitive it is. The camera work happens on your device and nothing leaves it. MARKING UP Fingerings, bowings, dynamics, cues and reminders, written with the Apple Pencil or your finger. A full set of musical stamps drawn in professional notation, plus text, highlights and shapes. Keep your marks on separate layers, so a teacher's notes and your own can be shown or hidden independently. Originals are never altered. SETLISTS AND PERFORMANCE Put pieces in the order you will play them, with markers for sections, intermissions or a note to yourself. Performance Mode clears the screen, keeps it awake, and preloads pages so turns never stutter. PRACTICE A metronome with tap tempo, count in and subdivisions. A chromatic tuner with adjustable reference pitch and transposition for wind and brass players. A tempo trainer that raises the tempo stage by stage. A recorder for takes you want to hear back. Your sessions and streak are kept so you can see the work adding up. WRITING AND EDITING Edit structured scores note by note: pitches, accidentals, dynamics, lyrics, whole staves. Write by hand on blank manuscript paper in the layout you choose. Export MusicXML, MIDI, a single part, or a PDF with your annotations included. PLAYING TOGETHER Lead a rehearsal over the local network. Everyone follows the same piece, the same page and the same place in the setlist. YOUR LIBRARY Folders, tags, collections, composers, genres and instruments, with search across all of it. Backup and restore when you want to move to a new device. DRAW MUSIC. Turn drawings into music. Every line you draw plays as music: height sets the pitch, colour picks the instrument, and shapes make rhythm. Choose from sounds like grand piano, strings and synths, add layers like tracks, and pick a style from lo-fi to cinematic. Made for every age, with no music knowledge needed. Export a video with your drawing coming to life, and share it anywhere. You can even turn it into sheet music and edit. BUILT FOR IPAD AND IPHONE Designed for the iPad on the stand and the iPhone in your pocket, with the layout adapting to whichever you are holding. Available in multiple languages.
