I finally found a decent drum machine which will sync to Cubasis' MIDI clock out!
It's the Molten Drum machine ... Set it to receive Clock In on all ports ( not just the Cubasis one ) and it starts, stops and follows Cubasis tempo!
Supports audio bus to record it once the beat is right, has a great grid pattern editor, per beat velocity , 8 tracks each with an assignable sound, import your own samples, per sound synthesis and some Filter effects and global reverb and compression. LOve it!
Hope this helps someone!
