Scarbee Imperial drums codes

[Paul_FX]

Hi guys.
Im trying to figure out the drum structure in Scarbee imperial drums, specifically the toms. Inside each folder there are OH and AMB folder which correspond to the Ambient and Overhead channels, but what are the TMA/TMB and FTA/FTB folders??
ALternatively can anyone point me in the direction of a pdf that lists all these abbreviations? In the manual it says
"Enclosed you’ll find a document explaining the abbreviations used
in this manual and in the library itself."
but for the life of me i cant find this document...

thanks
Paul
