Now here's the strange thing..........I tried using the second track slot in the drop down. I selected a new occurance of the synth and it appeard to load OK, but then it reverted back to original synth in the first slot leaving just the radio button selected but nothing in that slot.

I'm assuming from your comments that you have all tried this and it works OK? You can have 2 occurnaces of the same synth and select different patches in each of those synths...correct?

In which case it seems only me that has this problem..............or has anybody else have this?

Just tried it again...same thing. This time I was using Edirol Orchestrol.
