Real imPro — Jazz Solo Improvisation Studio

Real imPro turns any jazz standard into a personal solo coach. Import a lead sheet, pick an approach, and generate idiomatic, playable solos in seconds — with the notation, playback, and analysis tools to learn from every phrase.

【Key Features】

• Four Generation Engines
— Guide Tone Lines: clean 3rd/7th chord-tone skeletons as the harmonic backbone, with optional color tones.
— Grammar Engine: Basic (free) and Master editions generate vocabulary-rich lines from jazz grammar.
— Transform: embellish any line in the style of 26 jazz musicians — from bebop giants to modern players.
— Learning: an LSTM neural engine (Combination & Great Moments models) trained on jazz corpora for a distinctive, data-driven solo voice.

• One-Tap Generation: build a full solo instantly, then flip between “Original ⇄ Solo” to hear exactly what the generator added.

• Chart Import: import iReal-format lead sheets (.html / .irb) and generate on your own repertoire.

• 4-Track Backing Band: Sax melody + Piano chords + Bass + Drums, with independent volume and mute for each track.

• Interactive Sheet Music: high-definition vector notation with color-coded analysis — Chord / Color / Approach / Avoid notes — plus chord-degree labels and tonal key-section views.

【Who Is It For?】

• Jazz Musicians: spark soloing ideas, practice diverse styles, and study what the engine plays.
• Music Students: hear chord-scale relationships in context and build jazz vocabulary.
• Jazz Enthusiasts: enjoy real-time improvisations and explore different musical vibes.

【Basic vs. Master Edition】

The Basic Edition is completely free and includes Guide Tone Lines plus the Basic Grammar Engine.
The Master Edition unlocks the Master Grammar Engine, the 26-musician Transform library, and the LSTM Learning engine via a “one-time purchase for lifetime access”.
