Emax

Hi !

I've just picked up a EMAX II.
I'm very lucky because It is in a very good condition.
Furthermore the emax is very rare in Hungary.
That is very cool,user-friendly stuff.
But I don't know how I could  adjust the volume of the tracks in emax 
when Im working with an external sequencer.
I couldn't find it in the sequencer menu.
Kind regards
Akos
