Tonebank

An intelligent MIDI sequencer that generates melodies, basslines, and textures with built-in groove

Create Irresistible Grooves That Make People Move

Tonebank is an intelligent MIDI sequencer that generates melodies, basslines, and textures with built-in groove and structural strength. Instead of relying on simplistic arpeggios or random generation, Tonebank improvises inside rhythmically patterned harmonic loops—bringing logic from ancient traditions to your DAW.

Whether you're producing techno, house, hip-hop, ambient, or experimental music, Tonebank helps you quickly create musical ideas that are lively, interesting, and ready to shape into your productions.

The Problem with Most MIDI Tools

Most arpeggiators give you predictable, lifeless patterns. Most generative tools give you chaos. Tonebank is different—it uses proven rhythmic and harmonic strategies to create sequences that have natural movement, tension, and release. The result? Musical phrases that sound intentional, not random.

How Tonebank Works

Tonebank improvises inside rhythmically patterned harmonic loops, using organizational principles from traditional African music systems:

• 15 Harmonic Systems - Different chord sets (2-6 chords) that create distinct musical flavours
• Clave Patterns - Rhythmic structures where your harmonic changes occur
• Accompaniment Mode - Intelligent arpeggiator with control over density, pitch variance, rhythmic tension, and velocity
• Melody Mode - Generates phrases mimicking spoken language patterns with natural phrasing and rests
• Swing Patterns - Wide range of groove templates from straight to heavily swung (1:1, 2:1, 3:2, and triplet grooves)

Custom Harmony Editor

The new Harmony Editor allows you to build custom chord sets of up to six rows, input notes via an on-screen keyboard or MIDI, and save harmonies for reuse. This makes Tonebank useful as a composition tool for any style of music. You can now define exactly the harmonic language Tonebank improvises within.

Pitch Sliders

Move sliders up and down to adjust individual pitches within the harmonic framework, and see exactly which note will play at each position. Each slider has its own automatable parameter, so you can record adjustments for later editing or map them to a MIDI controller for live performance. Notes can also be activated or deactivated, giving you precise control over the rhythmic density of your patterns.

MIDI Control of Tonic

Tonebank’s Tonic — the root note that governs all harmonic output — can now be changed in real time via incoming MIDI notes. This opens the door to live key changes within a performance or arrangement. When Sync Instances is enabled, a Tonic change on one instance propagates to all linked instances, keeping your entire ensemble in the same key.

Tie Notes

A new row of Tie buttons beneath the grid lets you overlap the end of one note with the start of the next. This is particularly useful for monophonic instruments where you want slides, glides or portamento effects — great for 303 style basslines.

Custom Clave Editor

The Clave — the rhythmic backbone that determines where harmonic changes occur — can now be user-defined. Accessible from the Clave dropdown via “Edit…”, this lets you create rhythmic structures beyond the built-in patterns, opening up new possibilities for asymmetric metres and unconventional groove frameworks.
