Somehow the "External sync" capabilities are prolly less than adequate on 2 SBLive 5.1's that I paid a massive $19.00ec US for! :) Can midi control do this...they both have midi ports that show in Qjckctl? MTC is what I'm wondering....not being a midi genius I really dont know. Thanks R~ > > Good luck, > Mark
