AND WE'RE BACK.

Here are the steps I took to revive the MS-1:

0. Plug the MS-1 into the wall.

1. Connect MIDI OUT on my audio interface (Edirol UA-25) to the MIDI IN on the MS-1.

2. Check that the UA-25 was set up as a MIDI OUT device in Control Panel->Audio Devices.

3. Open up MIDI-OX to monitor MIDI.

4. Open MIDIBar (comes with MIDI-OX) and loaded the firmware file, O_S112S.MID

5. Hold down pads 4 + 5 while turning on the MS-1. It should read, "BOOT MODE" on the screen.

6. Hit play on MIDIBar. The MS-1 should read, "Receiving..."

7. Wait a few minutes until the MS-1 restarts itself.

8. Turn the power off on the MS-1. Hold down pads 1 + 8 to turn it back on and verify that the version has changed.

9. Finally, go through the Test Modes (see pp. 4-5 in the Service Manual) and format your flash card (see pp. 19 in the Owner's Manual.)
