Super vague question here, but I don't have much choice... How likely are El Cap drivers to work with Sierra? I have a MIDI pedal that has an editor to set it up via USB. Support is shady at best, and so there's no great plethora of users to ask if they've tried it yet. My MacBook has been slow and I'm gonna do a complete reinstall from fresh, but have been waiting for Sierra to come out. So I want to install it ASAP, but since that's a very important bit of software for me I'd like a good "guess" as to if it's highly likely, likely, not very likely, improbable, or it's completely random as to whether it works. I think with El Cap it originally had a problem because of security and where it was installed, which on previous version could be got around with some developer boot key thing, but they fixed that for El Cap. So anything new like that? It's some kinda USB (and I'm guessing to some kinda serial) driver if that changes things.
