A VAB program is the same as a MIDI patch.

A tone is a tone or sample. Up to 16 tones can be combined to make a
program (patch.)

Yes, within the limits of the min & max range specified for the tone
in the DEF file.

Yes, there are several sound samples in the SCEA DEMO files area.
SNDDEMO.ZIP is a very simple demo with a DEF file. Stan Weaver has
also provided some excellent samples there.

The MIDI patches should be matched to the programs as defined in the
DEF file.

>2. How do I get the instruments to be 'translated' correctly?

I'm not sure I follow your use of 'translated' here. Please explain.
