Just bought an OB6 desktop to go with my OB6 keyboard. Very disappointed so far - it's very likely to get returned.
For one thing - I want to have the two synths run at different clock speeds and have simply got them connected by 5-pin midi, no patchbays, nothing just a wire. Easy: set the desktop's Global MIDI Clock to Out. No - it still follows the keytboard's tempo. OK, set the desktop's Clock Port to USB. No - it still follows the keytboard's tempo. Is there a Global setting for 'do as you're told!'?
I've restarted both units (they are prone to ignore Global changes unless restarted). Keyboard is running 1.5.5 and desktop 1.5.8. Keyboard is set to MIDI Clock Out and Clock Port Midi. If I change the keyboard's settings to Clock Off or port USB, the desktop still stays in sync! Are these two things telepathic or are the global settings just for show?
So in summary I can change the desktop's tempo and they are now different but as soon as I change the keyboard's tempo, the desktop jumps to that tempo. That's not 'Midi clock Off', it's 'Midi clock off until the other instrument changes so now I'll copy it'.
