Has anyone on the list ever attempted to do a proper DJ style seamless mix

...

I've not... though have thought about it.... then thought...why?

That would be the purist in you John!

I imagine that matching BPM is quite easy... I have some software in which you can load a wave file ... push a button and it will tell you the BPM...

I need to have it John. What's it called? I've got loads of samples CD's that don't always give the BPM so it's trial and error doing all that time-stretching business. Shaun
