Chorder is a MIDI chord processor, allowing you to assign complete chords to single keys in a multitude of variations. These can then be played back live or using recorded notes on a MIDI track.

There are three main operating modes: All Keys, One Octave, and Global Key. You can switch between these modes using the Chords pop-up menu.

For every key, you can record up to 8 different chords or variations on so-called layers.

Operating Modes

In the lower left section of the Chorder window, you can choose an option from the Chords pop-up menu to decide which keys in the keyboard display are used to record your chords.

All Keys

In this mode, you can assign chords to each key on the keyboard display. If you play any of these keys, you hear the assigned chords instead.

One Octave

This mode is similar to the All Keys mode, but you can only set up chords for each key of a single octave, that is, up to eight different chords on twelve keys. If you play a note in a different octave, you hear a transposed version of the chords set up for this key.

Global Key

In this mode, you can set up chords for a single key only. These chords (that you recorded on C3) are then played by all keys on the keyboard, but transposed according to the note you play.

The Chord Indicator Lane

At the top of the keyboard display, you find a thin lane with a small rectangle for each key that you can use to record a chord. These rectangles are shown in blue for all keys that already have chords assigned to them.


In Global Key mode, the C3 key has a special marking, because this is the only key used in this mode.
