Opening a waveshare 2k screen

I bought this 9" 2k screen recently:

As I intend to use it for my synth, I want to extract the screen from the box - or at very least find a way to safely mount it and attach the cables inside the synth.

I contacted waveshare support, and while they said that they could not do this for me (not a problem) for such a low volume, they did send me some great pics of how to open the rear, which also means that I can possibly access and move the connector boards. I may not be able to fully remove the screen though, so I need to create some kind of bezel for it.

Oh, and I almost forgot - accessing the insides means I can connect wires to the on/off button to control it digitally.

Here is a cool ribbon cable based hdmi: https://www.aliexpress.com/item/1005002200767476.html?spm=a2g0o.productlist.0.0.726a3ff1r9Ggaf&aem_p4p_detail=2021071512223512888029912608890037608317

Super saw analysis ideas

I found a post on Matrixsynth today that lead me to a second paper analysing the JP8000 super saw.

This got me thinking - I still think the detune response looks like it consists of three linear components instead of a 11th order polynom like Adam Szabo shows in his paper (I did in 2014 as well when making my analog 7-saw module).

I really want to test my theory in detail, but that requires some automation. Here's my idea:

- Control the JP through webMidi

- Loop through all midi values for detune

- Use a js spectrum analyzer, for example https://github.com/hvianna/audioMotion-analyzer to find the frequency components. We should be able to find 7 distinct maximums (the 7 oscillators). 

- For each maximum, record the pitch and amplitude, possibly as an average over several samples

- Build tables for each oscillator/detune setting and calculate spread and pot response to see what the actual response is.

Edit: I've been looking at the Web Audio API lately, and using it directly could be a good option. It works by chaining nodes, one of them being a FFT node. I assume that can be used for finding the maximums.
