Here's a problem I've had for ages: I've got a H8000fw connected to a Mac and use Cubase 4. I'm unable to sync the tempo. I've enabled the MIDI clock in C4, I can see the busy light going on – indication MIDI signals – on the H8000fw when I do this. Then I go to the tempo in setup, and set the source ot Midiclock. Nothing happens, tempo will incate whatever I indicated before. I remember having troubles with it when I used a PC before, but somehow I got it working at one point.
