2023-03-16 (Th) EWC_Box Shuffling eight cards

I have a sampler with MIDI input, but I have never successfully connected it to a project. The input is a 3.5mm socket, but there is no standard pinning for those. I bought several inexpensive ones that did not work and considered making one, but I skipped the work and bought a compatible model.

My sampler supports eight sounds, a sufficient number of simultaneous instruments. I wanted to change which ones the machine selected, so it does not favor the lower numbers. I thought writing a function that "shuffled" eight numbers would only take a few minutes.

Computer PRNGs are not like cards. Instead, they are like dice. With cards, whenever you draw one out, it is eliminated from the queue. Dice can roll the same number because they have no memory. I fought with myself about the best way to approach the problem. I decided to have an array and prandomly generate a number, then check if that slot was empty. If the space was occupied, I would produce another value until it fit.

It took me all evening to conceive and code the solution, but it worked. I ran the code several times, and the output is visible in the serial connection window of the picture below.
