Viral Samples Call & Response MIDI v2.1.0 Standalone VST3 AU WiN macOS [FREE]

Call & Response MIDI is a generative MIDI instrument that creates melodic phrases through musical dialogue rather than random generation. Two linked lanes work together: the Call introduces a motif, and the Response answers it using strategies like mirroring, inversion, echo, or syncopation. It ships with 40 musical styles (Acid, Techno, House, Synthwave, Neo-Soul, Ambient and others), 38 response strategies, and 35 scales including diatonic modes, pentatonics, blues, and exotic options such as Hirajoshi and Hungarian Minor. Changing key or scale transposes active notes while keeping intervals and contours intact. An interactive 2D piano roll lets you drag notes to transpose with audio auditioning, slide notes across steps, and adjust gate lengths. A built-in 303-style analog-modelled synth with resonant low-pass filtering, envelope decay, accents, and slides lets you preview ideas without external routing. Eight preset slots (A–H) and vector parameter locks let you freeze style, strategy, scale, or motif while randomizing the rest. Export phrases via drag-and-drop in combined, call-only, response-only, or split MIDI channel modes. It suits hobby producers in FL Studio, Ableton, and Logic who want quick melodic starting points.
