It sounds like the issue is contrast and size… Any possibility of plugging in a full sized HDMI monitor? I’ve built up a number of “headless zynths” around an “Argon One” case and “Sabrent USB stereo sound adapter”. I connect this to a full sized HDMI monitor when needed… To the right hand side is the 4 encoder/ 4 button Arduino USB HID Controller which I use to control the zynth.
