Tonebank

Tonebank by Node Audio is an intelligent MIDI sequencer that generates melodies, basslines, and textures with built-in groove and structural strength. Rather than predictable arpeggios or chaotic randomness, it improvises inside rhythmically patterned harmonic loops, drawing on organizational principles from traditional African music systems. You get 15 harmonic systems, clave-based rhythmic structures, an accompaniment mode with density and velocity control, a melody mode that mimics natural speech phrasing, and a range of swing templates. The custom Harmony Editor lets you build chord sets of up to six rows and save them for reuse, while pitch sliders offer precise, automatable control over individual notes. It suits producers of techno, house, hip-hop, ambient, and experimental music who want lively, intentional musical phrases they can quickly shape into full productions.
