You mean something like this? https://youtu.be/D2IBGlDJ3lg
That’s something I’m trying to do (on a smaller scale) with a Pi and a MIDI keyboard.

I hate to “well, actually” you: but this is kind of my pet subject! (I was an editor for many years before getting involved in the founding of Raspberry Pi, where I’ve been working as Director of Communications since before we even had Alpha hardware; I still do some editorial work in that capacity at Raspberry Pi, although I wasn’t the editor on this post.)

What you’re referring to is not standard British English at all. It’s referred to as Oxford Spelling, and it’s distinct from more common British usage, where the -ise spelling is much, much more usual and is regarded as the standard; it’s taught in schools, used in our newspaper of record, and is what you’ll find in the vast majority of publications in this country. There’s a Wikipedia article about Oxford Spelling if you’re interested in the subtle differences.

In this country Oxford Spelling is predominantly used by scientific journals and in UN publications: i.e. in publications which are intended for an international audience. Oxford make a good historical case for the use of -ize, but if you’re going down that route you could just as easily assert that we should be using “thou” for the second person singular, which…wouldn’t be appropriate.

Here at Raspberry Pi we use a large and venerable – I’ve been working on it with colleagues since 2011 – house style guide which uses many elements of Hart’s Rules (which is itself derived from the Oxford rules); and we specifically exclude their rule on -ise/-ize. We’re not by any means unique as an organisation in doing so.

The style guide is written to ensure that we communicate in a way which is easily understood, which is appropriate for our audience, and which is consistent. Readers on both sides of the Atlantic are bright enough not to be too discombobulated by -ize/-ise: I can’t imagine there’s a single person reading this who doesn’t understand what a “synthesizer” or “synthesiser” are. We’ve come to the decision that as an English company, we should apply British English usage. Of course, when writing specifically for a US audience we have other rules (another section in the style guide), and would use -ize in that material. Language is constantly evolving, and I don’t like the prescriptivism that says there’s a right or wrong way of doing things. But (the style guide is not, unlike Fowler, unhappy for me to open a sentence with a preposition) Raspberry Pi prefers one spelling for the sake of consistency; and the consensus among linguists and, I’m afraid, professional editors, is that there is indeed a “correct” usage in British English.
