InstaScale: Relative-Note Scale Instrument Plugin by W. A. Production Free Download

Each playing key is assigned an offset, such as Home, Repeat, +1 or -3. The plugin combines that offset with the previously played note to determine the actual pitch. Polyphony works the same way: multiple notes can sound together, and stacked keys build chords. Because the order of notes matters, the first note created is processed first and later notes depend on it.

The scale list includes Major, Minor, Melodic Minor, Harmonic Minor, Spanish, Arabic, Major Pentatonic, Minor Pentatonic, Blues, In Sen and Hirajoshi, among others. Users can also edit existing scales or add their own in the full version. The home note can be moved from the root to any other scale degree, which allows different modes to be played or chord changes to be accompanied.

Every playing key has two menus: a mapping menu that sets its position on the controller using a list of MIDI notes, and an action menu that sets its behavior. Control keys use MIDI notes to step or switch the root, scale, home note and octave. Switch keys can assign a range of notes to specific values, so a single key press selects a root or scale directly.

The octave shifter moves the output up or down and can also move the input octave to a more comfortable playing position. A pass-through mode bypasses the plugin so the target instrument can be played normally.
