Much appreciated Sid. Nice to have a glimpse into how you go about it.
It was the Sid – The 9000ft PIANO.sfz that caught us out previously.
I remember now, that you had put the instruction in the .sfz itself (on where it needed to be placed).
Fortunately I was aware that sfz was text based and found the info that way. Once we got the file in the right place, it took a while to realize the volume controls are not in the front panel and that we needed turn it up !
