[A6] Help identifying a sound

[Andrew Eaton]

Hey there!

I'm the happy new owner of an a6.

I've been working recently on rewriting one of my brother's old modplug 
tracker songs using Live to sequence the A6 and various others.

I've been having luck with most of the samples, except for one.

So, can anyone help me figure out where this sample would have come 
from, and if so, if there is a patch that is close enough I can tweak it 
to match?

Thanks!
