Hi Squeak,
it was just Band in a Box. I wanted to use something other than coyote that comes with it.
Maybe it was just some of the samples gone faulty. My SampleTank goes back to version 2 . Sounds have been stored on a hard drive for years, Only loaded them back in when I bought SampleTank 3. Probably should have just forgotten about using the old sounds and just used Sample Tank 3 sounds.

Haven’t done anything with it for over a year. I was going to use SX900 with Biab, but something really weird going on with XG mode /Sx900/Biab,
so decided probably better off using a vst, bit more permanent than using a keyboard that I might swap down the track.
Hence I was looking at maybe upgrading to SampleTank 4.
I’ll do some more checking, hopefully it was just some corrupted files, and not my laptop.

Thank you so much, gives me a bit more confidence in regards to my laptop.
