I set up a basic beat in 'Ultrabeat', to use as a click. I don't need to hear it any more, but now I can't stop Ultrabeat from playing whenever I hit the spacebar. I've deleted every software instrument track. I don't see 'Ultrabeat' anywhere, but it still plays. Ghosts? thanks Logic Pro 9 ... Mac Pro ... OSX 10.6.8 ... MOTU Ultralite ..
