[sdiy] Techniques for Multiplying MIDI Clock frequency?

[Brian Willoughby]

Richie,

I encourage you (and others) to dive in to USB and USB-MIDI.

For the most part, USB is designed in layers, so you can almost completely ignore the vast majority of the complexity. The electronics, the hardware peripherals, and the low-level USB stack firmware will handle nearly everything locally for you.

Just learn about USB Descriptors - and that can be a serious PitA - and learn what makes USB-MIDI different from other USB Devices. At the high level, USB-MIDI is quite simple.

Granted, there are some details that aren't spelled out everywhere you might expect. So, it's often beneficial to study the other layers of USB - at least enough to get a basic understanding of how it works - and this extra knowledge will help you figure out the unwritten details that USB expert specification writers assume you already know.

p.s. If you can, use macOS. The support for USB-MIDI is way more complete. Of course, you'll also need to test with Windows for compatibility.
