10.6 MB
Call & Response MIDI is a generative composition instrument that replaces robotic randomness with musical dialogue. Built around the timeless musical principle of call and response, it generates interlocking melodic phrases, hypnotic acid basslines, and conversational hooks in seconds.
Whether you need a captivating lead, evolving counterpoint, or an instant burst of inspiration to break beat block, Call & Response MIDI gives you immediate musical results with complete tactile control.
Core Features
Conversational Dialogue Engine: Two interdependent lanes work in tandem—the Call introduces the musical motif, and the Response answers, inverts, echoes, or resolves it.
40 Musical Styles & 38 Response Strategies: Spans Acid, Techno, House, Synthwave, Neo-Soul, Ambient, and more with specialized algorithmic answers (Mirror, Invert, Retrograde, Question-Answer, Syncopation, Octave Leap).
35 Musical Scales with Dynamic Transposition: Switch between Diatonic modes, Pentatonics, Blues, and Exotic scales (Hirajoshi, Insen, Hungarian Minor, Byzantine). Changing scales or keys automatically transposes active notes while preserving musical intervals and melodic contours.
Interactive 2D Piano Roll:
Drag notes vertically to transpose pitch with instant audio auditioning.
Slide notes horizontally across step columns without scrambling the phrase.
Double-click to create or delete notes; drag right-edge handles to adjust gate length.
Built-in 303 Analog-Modelled Synth: Preview ideas instantly with an integrated acid synth featuring resonant low-pass filtering, envelope decay, accents, and slides—zero external routing required.
8 Instant Preset Slots (A–H): Save current states with Cmd+Click (or Ctrl+Click) and reload with a Double-Click.
Vector Parameter Locks: Click the padlock icons next to Style, Strategy, Scale, or Motif to freeze your favorite settings while randomizing the rest.
3-Way Split Views: Switch effortlessly between BOTH (dual stacked step grids + combined piano roll), CALL, and RESP.
Drag-and-Drop MIDI Export: Export generated phrases directly into your DAW timeline across 4 modes: Combined, Call Only, Response Only, or Split MIDI Channels (1 & 2).
