Plan B for me = I copied a selection of drum beats of sufficient duration to allow me exhaust the dancers/Audiences and I put em on Mini disk. So far I never had to use it. I suspect that Murphys law will apply IE I will forget disk on the night that x1 dies temporarily for sufficient time to render plan B necessary.I never use midi files or sequences. I would play the seperate piano and midi disk of drums if x1 died. So there you are PS I forgot I done the Plan B bit for six months or so last year!!!!!!!! good job X1 stayed firing on most plugs all the time. Pierce Best wishes DAve
