Hmm, there would be more space if you would not spend one line per pot on the title of the pot. If instead you would precede the dial with the first letter of the pot’s title that would save you 4 lines. E.g. if you would want to show ADSR values you could do it like this:
Attack
---------
Decay
---
Sustain
---------
Release
------
Note the - signs are meant to be the graphical representation of the value here.
But instead this would take up less space:
A: ---------
D: ---
S: ---------
R: ------
This might look a bit condensed, but who would not know what A, D, S, and R stand for?
You now have 4 more lines on the display. You could do this for the already existing pots.
B.t.w.: really nice project !
