Yamaha TX81Z Product Manual page 34

PERFORMANCE
In performance mode, you can use the TX81Z as up
to eight independent instruments, and preset the max-
imum number notes, note limit, reception channel,
voice number, etc. for each instrument. The TX81Z
will remember up to 24 of these "Performances".
Data (voice numbers, performance parameters etc.)
for each instrument is shown in the lower line of the
LCD. However, the LCD has space to display only
four instruments at once, so use the CURSOR keys
to move the blinking cursor to instruments 5-8.
