Real imPro

RealimPro — Jazz Solo Improvisation Studio RealimPro turns any jazz standard into a personal solo coach on your iPad. Import a lead sheet, pick an approach, and generate idiomatic, playable solos in seconds — or plug in any MIDI keyboard and trade bars with AI in real time. Interactive notation, playback, and analysis tools let you learn from every phrase. 【Key Features】 • Trading Mode (Active & Passive) — Connect any MIDI keyboard and trade solos bar-for-bar with the app. In Active mode you play a phrase, the app responds; in Passive mode the app generates continuously while you listen and comp along. Choose from four response engines — Modify & Rectify, Use Grammar, Use Transform, or Deep Learning — and set trade length from 1 to 16 bars. • 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 trading with a responsive AI partner, and study what the engine plays. • Music Students: hear chord-scale relationships in context and build jazz vocabulary through call-and-response practice. • Jazz Enthusiasts: enjoy real-time improvisations, jam along with backing tracks, 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". 【OPEN SOURCE & LICENSES】 RealimPro contains a Swift port of substantial portions of Impro-Visor ("Improvisation Advisor") by Prof. Robert Keller and Harvey Mudd College, used under the GNU General Public License v2.
