If you, like me bought an Edirol R-09 some time ago it might be worth checking you have the most up to date software installed on it. The current version is 1.31 and is well worth it as it allows you to record to 16 Gig flash cards rather than the previous 2 Gig. When you turn your machine on the current software version flashes up in the lower left of the screen.

The latest software can be downloaded from http://www.rolandus.com/products/productdetails.aspx?objectid=757 To install it you need the USB lead that came with your Edirol and a blank flash card (the data on mine did survive the process though). They also advise that you run the unit on mains power while upgrading. Installed fine via my mac too.

For the up to date software for the newer recorder, the Edirol R-09HR go to http://www.rolandus.com/products/productdetails.aspx?ObjectId=960
