Hi Arturia team and community,
I’d love to request a static LED scale highlight mode for the KeyStep 37 Mk2.
Currently, the per-key LEDs only react when notes are played — in Scale mode, notes within the scale light white and corrected notes light green. This is great reactive feedback, but what’s missing is a way to see the scale laid out on the keyboard before playing anything.
The request is simple: add an option (ideally a toggle in MIDI Control Center, or a key combination on the unit itself) to permanently illuminate the LEDs for all notes that belong to the currently selected scale and root. This way, you can visually orient yourself on the keyboard before and during playing — essentially turning the KeyStep into a visual scale reference at a glance.
A few implementation thoughts:
- A dimmed white or a distinct third color (e.g. amber) could mark scale tones statically, while the existing white/green reactive behavior layers on top during playback
- It should work independently of quantization — users should still be able to play accidentals freely; the lights are just a guide, not a lock
- Toggling it via MIDI Control Center would be the least intrusive approach
This would be especially valuable in DAWless and hardware-only setups where there’s no screen or DAW showing you the scale, and it would make the KeyStep 37 Mk2 a genuinely useful learning and performance tool for players who are still internalizing scales and modes.
The hardware clearly supports it — the multi-color per-key LEDs are already there. This feels like a firmware-only addition.
Thank you for considering it!
