no testers?
i just formated my whole pc and did a clean re-install of Windows Xp SP2 Pro. Installed the RME Fireface 400 drivers, MS wireless desktop (included with the xp installation), Cubase 4 + USB dongle and de TI 30300 drivers/software.
The problem stays the same... even with a new empty project and virus ti notes on the beat like this (x--x--x--x--etc).
Also did a test with Cubase LE4. Same problem.
