Hello,
Since we have five different lanes corresponding to five different parameters (octave, velocity, trigger, gate, slide), it would be more clear if each lane has its own color (be it the background, the outline or just the 16 sliders).
Example: octave = blue, velocity = yellow, trigg = white, gate = green, slide = pink.
I know there is already a graphic chart (yellow for LFOs, green for functions, etc.) so the alternative would be different slider shapes (rectangle, rounded rectangle, dotted rectangle, etc.) so that we instantly know what parameter we're currently editing. Or anything else that could create a difference between one parameter and another. Maybe just light grey every other lane could be sufficient.
What do you think about that? Don't you think that the superposition of five identical GUI lanes are a little raw?
