I listened to the TrigSlave file a number of times and then tried one of the test files for it, it worked like a charm.
So then I had the idea of splicing together a load of files to make a new trigger file and this is where the problem started. I had to listen to the trigger over and over gain while making the file and I had to fight really hard not to go under. So now it doesn't work! Bugger.
I'm sure if I listen to the TrigSlave file over and over again I’ll be able to get it working again but I can't then make my own files because the same thing will happen again.
I was wondering if anyone had any ideas on how to work round this problem or maybe even better if there was a site that had pre recorded trigger files I could listen to.
