OK. Here goes ;)
1. load a voice.
2. goto page 7. Press alt/ctrl+x to copy. select next voice. Press alt/ctrl+v to paste this voice as a reference - do this 4 times so voices 1,2,3,4 are the same
3. goto page 3 voice. you should see the four voices. click to select the first voice. At the bottom SET NPHONY to 4 - voila you should have 4 voice polypony
.vc is just the current voice, .in is all the voices, .rs is just the sequence data and voice references. if the voices are in the same location as the .rs file is will load them, if they are in different locations then you will get a list of missing voices.
What you are looking for is .sy. This is the current system including voices, rs data, system setting - the entire lot :)
I've checked out the files and heres the correct answer:
files come in 2 type 16k sample & 21k sample+harmonic data
the loop points are found in the corresponding .CO file - which you will need to load manually.
To do this. locate the .co file with the same filename. click the voice to load this info into (usually the same as the voice file) then click LOAD. that will load the loop points and any other data into page 7 ;)
