ChordFlow: Piano Chord Trainer 앱 분석 (10월 22일)

ChordFlow turns your iPhone or iPad into a chord practice room. Play a chord and see its name instantly, build fluency with three sight-reading modes plus Cross-Key Practice, and improvise over the built-in accompaniment machine. Practice on the touchscreen, or connect a MIDI keyboard or digital piano. REAL-TIME CHORD RECOGNITION • Recognizes 45+ chord types: triads, 6ths, 7ths, 9ths, 11ths, 13ths, sus and added-tone chords • Correctly names inversions and slash chords like Dm/G • A rising waterfall visualizes every note you hold • The sustain pedal (CC 64) is handled separately for sound and for analysis, so holding the pedal never blurs one chord into the next PRACTICE MODES • Zen: no timer. Optional chord-tone hints, plus a grace window for pedal legato • Groove: play on the beat. The metronome keeps time and scores the timing of your first note • Fast: pure reaction. Nail a chord and the next one appears — chase your best BPM • Cross-Key Practice: Transpose and Mixed Keys drills OPTIONAL MIDI KEYBOARD • Every feature works on the on-screen keyboard, which adapts to your device • Plug in a MIDI keyboard and the view expands to all 88 keys — connect or disconnect anytime • Velocity and sustain pedal supported • Prefer the sound of your own instrument?
