Chord Analyser vs Roland Chord Director

Chord Analyser identifies chords entered as notes on a piano keyboard or fretboard, then shows playable positions for the selected chord. Its library recognizes over 3,500 chords, and its chart editor supports measures, subdivisions, repeats, time and key signatures, playback, auto voicing, and PDF export. The free version costs nothing, has no time limit or ads, and includes one chord chart. More charts require the full version, a one-time payment whose price comes from the app store. That version adds eight instruments, open tunings, MIDI input, unlimited charts, and chart transposition. Microphone recognition is an Android-only beta; it identifies one chord at a time and may struggle on older phones. The maker says audio transcription happens on-device without an internet connection. The app is available for Android and iOS and is described for learners, composers, performers, and musicians who play across instruments.

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.
