Cordial turns a key, a mode, and a progression into five working parts — one shared backbone driving four independent streams of MIDI, each on its own channel.

Designed for quick ideas and easy sketching, whether you’re a seasoned pro or just getting started.

Comes with dozens of presets spanning multiple genres for quick inspiration.

The backbone · shared by every part

Progression

Set a root key, a mode, a chord-progression preset, and a seed. This is the harmonic backbone every other part is built on. Reroll the seed for a fresh idea in the same key — or lock it once it’s right.

One progression, four parts

Each layer reads the same backbone but carries its own rhythm, register, velocity, and style. Enable only the ones you need — each plays out on its own MIDI channel.

Chord

MIDI ch. 01

The harmonic foundation. Cordial voices each chord in the progression as pads or stabs, with its own rhythm and register.

VoicingRhythmRegisterVelocity

Arp

MIDI ch. 02

Movement over the same chords. Set the rate, pattern, and direction, and the arp follows every change in the progression.

PatternRateDirectionOctaves

Bass

MIDI ch. 03

The low end. Root motion that tracks the changes, with its own groove and octave so it sits under the rest of the parts.

GrooveRegisterVelocityStyle

Melody

MIDI ch. 04

The top voice. A lead line generated inside the key and mode you set — change the seed for a new phrase over the same chords.
