AlphaTheta Chordcat Groovebox

Chordcat Groovebox - Find Harmony, Spark Creativity!

Whether chords, patterns or effects — with the ChordCast you can craft musical ideas in a flash. Intuitive controls, flexible I/O and a compact design make it the perfect companion for the studio and on the road!

Chord Cruiser Mode

Generate up to 110,000 chord combinations to build your own progressions.

Put the groovebox into Chord Cruiser mode and an exclusive algorithm pulls several musically compatible chords from its database and suggests them to you. You can preview these chords and assign your favorite to a button, which automatically triggers the next suggestion.

This intuitive workflow lets you create your own tracks with ease.

Three Built-In Effects

Control 3 built-in effects intuitively via the XY pad:

• Arpeggiator: Generates melodies from chords.
• Delay: Gives sounds more depth and adds a spatial dimension to your music.
• Ducker: Adds dynamics and emphasis, creating a sense of motion in your tracks.

Running Direction Feature

Change the playback direction of 4x4 step-sequence patterns with a single button press.

Choose from four options — right, down, clockwise and counterclockwise — to uncover new phrases and rhythms. This feature opens fresh ideas, letting you craft innovative chord sequences or explore rhythms from different genres.

145 Sound Presets + 16 Drum Kits

Designed for a wide range of genres, you can spark new ideas during the creative process by switching between 145 sound presets and 16 drum kits.

Shape your sound presets with the low-pass filter and amp envelope to taste. These parameters can be automated per pattern, so you can change both tone and chord progression dynamically — creating lively phrases.

Key and Scale Settings

Play with creative freedom and never hit a wrong note. When you set a key and scale in Chordcat, only the notes belonging to that key and scale are mapped to the keyboard.

Generous Workspace and Versatile Connectivity

Chordcat's workspace offers 8 tracks, 16 patterns and 128 steps (8 bars). Thanks to MIDI OUT/THRU, MIDI IN and USB Type-C ports, Chordcat easily integrates with external synthesizers and DAW software on PC/Mac.
