Sorry to be a nuisance, but I've searched this on google and also on the v-synth (www.v-synth.com) and the rolandus site and I can't find it.

The new update is a Zipped 13MB file, which is fine until you download it and find it only contains two files, neither of which is exacutable !

v-synthdiskimage.bin
v-synth.rom

WTF Roland don't provide an easy to find step by step guide on how to use their updater I will never know.

These sound like CD writer files to me. Any idea how to use them ?
