ChordSQ is a player instrument for the Reason rack designed to help you create chord progressions. The device interface offers an intuitive way to achieve results fast. It’s easy to create or modify progressions in just a few clicks. No drawing of notes required.

At the heart of the player is a 16-step sequencer which can be synced to the host transport or can be triggered by MIDI notes. For each step of the sequence, you select a root note and choose a chord from the many available presets. Then you can change the chord voicing, add a bass note, set a duration and velocity. Each parameter has dedicated edit menus so that the selected steps can be altered easily.

To help you choose chords, set a key and scale and all compatible chords for each scale degree are available from the chord type menu.The interface conveniently highlights which notes and chords are in the scale. A customizable randomization engine can help spark new ideas, but if you want to to keep things in check, all outgoing notes can be quantized to the selected key and scale.
For a selected number of scales*, it is possible to automatically generate chord progressions and chord sets in one mouse click!

The device has four operation modes. In mode 1, any note triggers the sequence. In mode 2, a note triggers the sequence and it also transposes it up or down (no transposition when you play C3). In mode 3, notes C1 to D#2 play the chords in slots 1 to 16 without triggering the sequence. This mode turns the player into a one-finger chorder which can store up to 64 chords per patch. Finally, mode 4 provides host transport sync so that the chord sequence starts, stops and runs in sync with the Reason playhead.

ChordSQ is fast to program, fun to use and it encourages experimentation. Try it out and see for yourself!
