Safe longest USB cable length?

Post by EnjoyRC » Tue Jan 15, 2019 10:23 pm

What is the longest safe length of USB cable that can be used for a MIDI controller to a Mac running Ableton Live 10?
I'd like to have this sit by another musician on stage away from my keyboard setup.
MacBook Pro (MacOS 10.14.x) Surface Pro (Win 10)
(STUDIO I/O) MOTU UltraLite mk4 (w/ADA8200), (LIVE I/O) Behringer X Air XR18
Ableton Live Suite 10, Reason 10, Studio One 4

You can also get powered extender cables for USB 2.0 up to 20m ... rk:22:pf:0

For the $20-30 it's worth getting one and testing it out. There are also unpowered extender baluns that use a CAT5/6 cable connection but typically these work at the USB 1.0 speed which is normally fine for a keyboard/mouse or simple MIDI device. Wouldn't recommend either for audio or HDD extender cables tho.

I run one to my controllers which is about 5 metres, but there's a powered hub on the end of it. I'm sure there's probably a latency penalty of a few milliseconds as the electrons make that epic journey but I don't care that much.
