Today when I switched on my EX800 all the factory presets had gone.
Weird thing is that now all the odd numbers (11...87) have the same
whooshy type noise and all the even numbers have a slightly
different whooshy noise.

The previous day my PC had crashed during a Cubase session and my PC
stopped receiving midi data for a while. Is this a red herring or
could the PC have chucked out some fucked up midi data?

A previous post suggested such whooshy-ness could be due to the
battery - in that case what do I do now?
