I'm not near my studio so I can't say for sure, but have you tried going into the Syncronization settings? Pressing the G key on your keyboard should get you there. I'm not certain if it's there or not, though.

I have to be honest.
When I first started using Samp 6.04 I could not fid a quick way to do metronomes either so I bought a cheap Boss metronome with a line out($40).
I simply adjust the beat to what people want and record it to a track, either before they track or at the same time.

You can then create a grid to the known tempo ( I use like 3 times tempo for finer graduations) and line up everything to the grid. It makes it a snap to edit timing.

i think i've figured out the metronome thing, (which i'll explain later cause it's tricky and i have to go to work now), but now i move onto another question. when i used cool edit pro i could record the same file to many different tracks. all i did was set a bunch of different tracks to record at the same time. how can i do that with samplitude? it'll only let me select one track at a time.
