SELECTING A VOICE
@ Overview
100 preset FM voices are yours for the choosing. Each voice
has its own number, indicated in blue next to its name in the
VOICE LIST (5), for instant access.
Selecting a voice is very easy, requiring only one or two steps:
@ Operation
1. Make sure the VOICE indicator is lit.
Check to see that the dot in the VOICE/STYLE number
display (8) is located above "VOICE".

This shows that your PortaSound is ready for voice se-
lection. If it is not, simply press the blue VOICE switch
(11a), making sure that the VOICE indicator dot lights
up.
2. Enter the voice number.
Use the VOICE/STYLE SELECT number buttons (1 1c)
to input the number of the desired voice.
Points to Remember
Notice that all voice numbers have two digits. Both
must be entered for the instrument sound to change.
(The first ten voice numbers start with a "0", which
you also have to input.)
You can always check the currently selected voice by
looking at the VOICE/STYLE display (making sure
the VOICE indicator is lit).
When POWER is turned on, the voice chosen before
the PSS-780 was turned off is selected automatically.
With each voice, up to twelve keys can be played at
the same time — in other words, the PSS-780 is 12-voice
polyphonic.
To appreciate the amazing variety of realistic FM instrument
sounds now at your disposal, try out as many voices as you
like right now.
Playing Along with the Demo Song
If you want, you can even play along with the demonstration
song using any instrument of your choice. To do so, select
a voice, press the yellow DEMO
START/STOP switch and
play. You can change to other voices any time.
and input its two digits during a performance.
