I'm trying to learn how to send USB commands to my Korg Kross from an embedded Linux board (that is, running on an ARM processor). The Kross show up as a USB device (/dev/usb/001/004), but I can't figure out how to get a simple program change midi command to work. I've tried every iteration of "echo c0 /dev/usb/001/005" followed by "echo 55 /dev/usb/001/55", which would change to program 55 (or the decimal equivalent) but nothing's happening on the Kross. I'm a little new to Linux, but, you know, how hard can it be?
Anyway, any pointers (no pun intended) would be really welcome.
Thanks!
Craig
