Hi everyone,
            I have sps-1 and I am haveing midi timeing problems, 
Untill I bought the sps-1 and the m-audio 2x2 interface which the 
machine drums midi is attached too, I had no problems. I also have a 
roland v synth, and a polyevolver which dont have timming issues. I 
have done all the usaul stuff as in use timestamp option in devices 
in cubase/nuendo and I have set up the global menu in the sps-1, to 
best of my knowledge and the mannual. I am hopeing that you guys 
might know something I dont.....so if you have any tips or options I 
have missed could you please drop us a reply.

Many thanks, and thanks for your time stefan
