Simple Scaler

Simple Scaler is a scale filter that allows customizing the notes of the scale. Its options are inspired by one of the early Audiobus MIDI filter apps that doesn’t look like will be updated to AUv3 MIDI.

This is meant to be a quick and simple tool. For an amazing full-featured scale script, check out Scale Compendium by Bryan Appel

Simple Scaler v2.2

Set a root note and scale. The pads will light to reflect which notes are in the scale. You can add or disable notes by tapping the pads. Changing the root note will keep the same pattern but change the scale notes so you can transpose easily.
▫️ In Nearest mode, the closest scale tone will be played for notes not in the scale. If the distance to a valid note is the same then the higher note will be uwed.
▫️ Filter plays nothing if notes aren’t in the scale.
▫️ Chromatic mode (not scale) plays the root of the scale on C and then up the scale for each successive key. If there are fewer than 12 notes the higher keys do nothing.
▫️ White Keys is the same, but only responds to the seven white keys. If there are more than seven notes in the scale, the top notes will not play. PassThru allows all notes through.
▫️ PRESETS: The current scale can be saved to one of the four preset pads. Double-tap to SAVE (pad turns green), Long-Press to RECALL.
▫️ CC CONTROL: to enable changing the note filter using MIDI CC’s change cc_control = YES in the @Settings section and remember to press Upload, then save the script. See the notes for usage. Default = NO

IMPORTANT: To avoid stuck notes, only make scale changes when notes are not playing.

    Thanks for the script.
    Is there a way to program a mode like the Chromatic(no scale) that when the scale ends it won’t “do nothing”.
    I want it for my Launchpad. at the moment its abit unusable when the scale ends there’s no active notes.

    As I understand it the grey notes are not in the scale and should not play.
    But there are some keys like f minor that play some greyed out notes.
    Is that a bug, or am I missing something?

    Hey all,
    Version 1.1 fixes problems finding notes and flashing the wrong pads when root has been changed. Sorry ’bout those bugs.

    Version 2.0 adds four preset slots to save and recall scales. Double-tap one of the four preset pads to save, long-tap to load. Thanks to @rs2000 for the idea. 👍🏼

    Thank you very much for this useful feature enhancement.

    I decided to add midi thru for messages other than notes so that CC’s and other messages can be passed through. Only notes are affected by the plugin as of v2.1. Otherwise the script is unchanged from v2.0.

    Version 2.2 adds a (disabled by default) option to toggle scale notes via MIDI CC in addition to with the pads. See the notes in the @Settings section for details.
