SongKeyPad

SongKeyPad is a compact music-analysis tool styled like a hardware macro keyboard.</strong> 

Drop in a track — or record a passage through your microphone — and press FLOW: you get the tempo in BPM, the musical key, and a timestamped, editable chord timeline. Every result comes with an honest confidence percentage, so you always know how much to trust it.

Private by design

Everything happens on your PC. SongKeyPad contains zero networking code. No uploads, no accounts, no analytics, no ads. Your audio never leaves your machine — read the privacy policy.

For musicians, producers, and DJs who want quick answers

• BPM, key, and chord progression in seconds, with confidence percentages and alternate readings
• Song map showing sustained tempo and key changes across the track
• Editable chord timeline — fix boundaries, retag chords, undo/redo, nudge changes by 0.1s
• Chord inspector that plays back any chord or single note
• Playback with speed knob (0.5×–1.5×), range looping, and click-to-seek waveform
• Select any part of the waveform and analyze just that section
• Export to text, CSV, or JSON — copy the progression with one key
• Microphone quick-scan: record, stop, analyzed automatically
• Seven color themes plus Adaptive, which colors the app from the song's key, tempo, and energy
