Hey William, Ho hum...,
Cheers for having a look though. I'm not completely clear about the continuation flags? I can see from the help file that they're there but what do they mean? Perhaps this should be a new thread but why does sigmund have a frequency range of 100,000hz, and what would be a decent useable range from practical experience?
