Here are the instructions posted by Phil on the yahoo group forum on how to download the 4.0 system for the Mark IV:

I downloaded the firmware via the PRC menu - Network update. Took about 5 mins to download with a 8Mb broadband connection.

It then asks you if you want to reboot now or later. I selected Reboot now.

After this, the PRC would not reconnect. So I had to manually push the power button on the piano to take it out of standby.

When the PRC reconnected, it said that I should update the PRC Interface from v3.0 to v4.0 - it did not do this automatically.

To do this I had to go into the main PRC-100 menu (using the icon in the bottom left of the screen) and select 'Interface Updater'

After a brief message saying it is 'Searching for update file...' there were the following 3 updates possible:

Application Current Version Next Version
Interface 3.0.0 4.0.0
PRC-100 Menu 1.1.0 1.1.1
Service Center 1.1.0 1.1.1

I selected all of them, and then pressed 'Install'

A message saying 'Downloading...' appeared on the PRC for about 30 seconds and then 'Updating...' for about 1-2 minutes.

A message then appeared saying 'Interface program updated successfully' - tapped
