Hi - there are a number of tutorial files eg Downtown with Sonar LE but I have never worked out where the instruction on what to do with these are - I have looked at the help file and the manual but these just have general walk throughs all of which I have done

Well they are sample projects. You can do whatever you want with them; change the drums, substitute a grand piano for the Rhodes piano; alter the automation parameters; add effects, etc.
They're there to give you a starting point for working with MIDI and soft synths and adding effects.
Have you opened any of them to play around with?

Ah thanks - yes I've had a quick look at them a couple of times and thought there may be some specific instructions to go with them but if they are just there to mess around with I have some of my own pieces now that I do that with Thanks for the help - thought I was missing something :-)
