kbrkr and all: As stated on a separate thread, Yamaha adding the new HDD mode feature which treats the Tyros HD as another storage device, viewed & accessed directly via Windows Explorer at normal fast PC file transfer speed (finally) is fantastic. The ability to defragmnent, optimize, and virus scan the Tyros HD via the PC is yet another added plus.
it's IMPORTANT to note though, that in order to take advantage of the new lightening fast USB speed, you need to first reboot the Tyros (while holding down the Music Finder button).
This is fine when backing up or transfering a lot of data, or for file reorganization & file re-naming projects, but . . .
when working on a Tyros song project which requires continued access & playing the Tyros keyboard while transfering a few files to the PC in the middle of a session project (such as naming Registrations via Heiko Plate's 'PSR Reg' utlity or editing a Music Finder file via Michael Bedesem's 'Music Finder View' program) and then moving the file(s) back to the Tyros right away, I prefer to continue to utilize the slower Yamaha 'Tyros File Utility'for Tyros to PC USB connection, as this allows you to continue to play the Tyros Kb before, during, and after files are transfered back and forth without having to reboot the Tyros. The other thing to note is that once you're in 'HDD' mode, to release the USB connection, you must manally go into the Windows System tray and select the USB icon to release the connection before shutting off the Tyros and rebooting.
I'm enjoying the Tyros more than ever now.
