Huge time-saver ★★★★★

I have a 32-year-old Roland U-20 keyboard, and after I had the internal battery changed, the keyboard lost all of its default patch data (the display showed nonsense characters, and wouldn’t play any internal instruments). The Roland company sent me a .MID file and instructions on how to set the U-20 to receive the default patches. I simply added a Roland U-20 device to MIDI Studio on the Mac, and connected the MIDI In and Out ports to an internal Mac MIDI device. MIDIPlayer X was extremely simple to use: I turned off Auto-Play and sent the data to the U-20. Problem solved, without spending weeks trying to figure out one of those complicated software sequencers.
