Register, registerfamilies,registration
In music a register is a group of sounds that belong together on the basis of pitch or timbre.
There are 4 families: flutes,diapasons,strings,reeds.
Flute family : recorder,picolo,tibia,....
Strings family: viola,alro,,cello,douvle bass....
Reed family : trumpet, clarinet,boe, trombone...
Diapason or principals
In the organ family we find 16,8,4,2,1 (and some more)registers under drawbars.
So a registration is a configuration of several sound registers.
From the KN6000 these registers can be found in the soundgroup and assign the desired parts to sections of the keyboard in Left,right2, right1 .
Hopefully this info is useful.
