Keyboard faceplate rough layout
The LCD needs to be thin enough to fit between the LED PCB and the frame (about 6mm, 250th). Luckily I have a Optrex DMC-16106A hanging around.
A side note I removed the LCD backlight so I can substitue a LED one, just easier to deal with using +5V instead of having to add additional power conversion just for a backlight.
The pots also need to be low profile, and I'm able to add 5, which works out nicely with the 3 original potientiometer controllers so I can use them all with a single Vishay DG408 analog multiplexer since it has 8 outs.
