Due to the size of a legacy iMac hard drive that has Mac Band in a Box 2017 application it has to find the real tracks/drums/demo's etc that are on a USB drive.

Now you would think i should know this however no, i don't and can't readily find the instructions in the in application manual. This is the first time for me to even do/try this

How do I aim the Mac Band in a Box 2017 application to the USB drive that has the real tracks/drums/demo's etc. ?
