Chord Analyser vs SongEngine

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.

SongEngine creates chord progressions and generates matching basslines, phrases, and melodies. Users can make chords with Chord Pads, import MIDI progressions, or generate progressions in the plug-in. Its free core includes 60+ presets for basslines, arpeggios, phrases, and melodies. Live Mode turns MIDI chords sent from a keyboard or DAW into new MIDI phrases in real time. Generated parts can be dragged into a DAW as standard MIDI files; an optional MassExporter can write hundreds of phrases to a computer folder. SongEngine runs as a VST2, VST3, or AU plug-in and needs a compatible host such as FL Studio or Ableton Live. It supports 64-bit Windows 7, 8, 10, and 11, and macOS 10.13 or later on 64-bit Intel or Apple Silicon processors. There is no official Linux build, though the manual says users have reported using Wine. The maker says its algorithms were crafted by human musicians, not AI, and generated MIDI files may be used in commercial releases.
