Hi Andy,

I could reproduce this issue - the (old) version of libusb is missing. Given you have Homebrew installed, run:

brew install libusb-compat

and let me know how that went.

[andyOfOtter]

Will try that now on the 10.10

BTW cool that you're trying it out! I guessed the number of people still using hardware samplers has slowly declined over the last years :-)

I was quite prepared to go the old school route (despite having the altogether rare USB board) but then saw your github! My bet is if an AkSys replacement was well know there will be a revival…. I’m afraid Homebrew install failed: After installing Xcode tools (thought I had it but Apple thought not) and a Veeery long wait I got: ==> Pouring portable-ruby-2.6.3_2.yosemite.bottle.tar.gz Warning: You are using macOS 10.10.

OK. Just tried on the 10.12 machine. Home-brew installed fine with a different command.

brew install libusb-compat
