Chord ai vs Roland Chord Director

Chord ai is a mobile app that recognizes chords and beats in songs, helping listeners follow music or learn to play it. Songs can be loaded from YouTube, SoundCloud, audio files, or a device microphone. The app detects chords, tracks beats and downbeats, displays tempo and song structure, and infers a song's key; it also shows guitar, piano, and ukulele chord diagrams. Microphone input can identify chords in real time. The maker describes on-device deep learning, with audio files and microphone input analyzed on the phone. The free plan provides basic features with unlimited free use. Chord ai Pro adds recognition of more than 700 chords, voicing and position suggestions, unlimited saved songs, PDF transcription export, score editing, and WAV export of bass, drums, vocals, and other stems. Other Pro tools include pitch shifting, alternate tunings, smart capo suggestions, and processing audio or video up to one hour at once. Pro costs $9 a month or $69 a year, with prices depending on App Store country. The app is available on Android and iOS, and the maker does not provide API access to its technology.

Roland Chord Director is a free companion app for Roland’s GO:KEYS 3 and GO:KEYS 5 keyboards. It supplies additional ready-made chord patterns that can be loaded into a connected keyboard with a touch. The touch interface also lets users change keys and edit chord patterns, or create new patterns from their own chord progressions. The app links to the keyboard through Bluetooth and is listed for iOS and Android through the App Store and Google Play. Roland describes it as a way to use chord patterns for favorite songs and new compositions with a full-band sound. A free Roland Account is required to access pre-made patterns. Roland says GO:KEYS 3 and GO:KEYS 5 added support in system program version 1.11. Product questions go to Roland’s Knowledge Base, with product support handled through BACKSTAGE. Google Play reports possible collection of personal information, app activity, and device or other IDs; it also reports encryption in transit and deletion requests.
