Apple is a hardware company, and you can't WFH using giant anechoic chambers, laser cutting machines, electronics labs, and who knows what else. The products may be manufactured overseas, but there is a lot of expensive hardware needed for designing, prototyping and testing.
I get that Apple does a lot of software these days, but one of the things they are also known for is tight integration between the hardware and software, which doesn't happen without them working side by side.
There may be a significant fraction of employees that can work remotely, but it would significantly change the culture of the company to split the workforce like that.
> I find this tool an interesting concept, but I couldn't get through the initial step to create a 4/4 kick loop. There's too much internal state going on with no indicators about what's active or what mode I'm in that it feels more like a memory game than a fun music toy.
I think it should be set up such that you can immediately, intuitively start making things as soon as you visit the page. It should feel like a fun music toy.
One web app that does this really well, in my opinion, is http://sampulator.com - you just start pressing keys and you get sound; you press shift and you start recording tracks. It's very simple and intuitive. It doesn't have nearly as many capabilities as your app, but I feel like friction is one of the biggest issues with digital music making, and if you want to stand out, providing something people can wield as an instrument without even thinking about it will be a huge advantage.
