The constant value 170 in line 192  ( ld  a,170 ) is not really constant. 
This value can be modified by user as parameter in otlaBuilder GUI. And the 
desidered
value wil be compiled in the wav file. It's responsability of user to set a 
correct
value. The original basic loader in a .cas file should show some clues. 
Specific msx
model should be considered. I don't really know
