Your fretboard just came alive. This update turns redLUX into a hands-on way to actually understand the guitar — not just look things up. • The CAGED system finally clicks. Slide any chord shape through all five positions up the neck and see exactly how they connect — the "aha" every player chases. Every position is free. • Watch chords move. New interactive triads with voice leading: pick a target chord and watch each note glide to its nearest shape. There's no clearer way to see how music moves under your fingers. • Solo with a map, not a guess. The redesigned Improv builds you a solo sheet from a key, your own chords, or a Songbook import — and shows the exact scales that fit what you're playing. • Write like a pro. Progression Studio now builds from the full chord catalog, with lush new Bossa Nova voicings and smarter reharmonization. Plus more realistic chord fingerings, cleaner PDF and image export, sharper scale diagrams, and a long list of fixes. New to redLUX? It's the all-in-one tuner, chord & scale trainer, backing-track jam station, and songwriting studio that shows you the notes that matter — so you learn faster and sound better, without juggling five apps. Thanks for playing redLUX. Keep the feedback coming — we read every word.
