What is NaturalPlay?
"Wait! Wait!
What key is it in? What key is it in?"
A device creating harmony voices and correcting
what you are singing to the right scale is a won-
derful thing. But how do you tell that device what
key the next song is in? Do you have to program
it as part of a Preset? Do you have to set it up for
each song? What if you get it wrong on stage?
NaturalPlay to the rescue! If you have a guitar
connected to VoiceLive 3, it will automatically
guide key and scale for any Harmony voices or
HardTune effects. You don't need to make any
changes to the system for this to work. Just play
your guitar normally (chords work best) and sing!
Similarly, if you connect a MIDI-enabled key-
board using a MIDI cable, VoiceLive 3 will follow
your playing to determine key/scale for Harmony
voices and HardTune.
If you sing to backing tracks and don't have a
guitar or MIDI keyboard connected, VoiceLive 3
will read key/scale information from a music
signal present at the Aux jack – this might be
a backing track from an MP3 player or smart-
phone. Finally, VoiceLive 3 can also read key/
scale information from the Monitor In jack.
As you see, NaturalPlay has you covered – no
matter what your setup is.

Using Global Key/Scale
If you do not have an instrument or backing
tracks that can guide VoiceLive 3's Harmony
and HardTune features, you may want to make
a small change to the System setup so you can
define the key and scale for the song you are
singing and change Presets without having to
change the Key setting each time.
– Press Setup.
– Use the < and > Arrow buttons to navigate to
the System tab.
– Using the Control Knob to highlight Global
Key/Scale.
– Change the Global Key/Scale to ON.
This will set one global key/scale for all Pre-
sets in VoiceLive 3.
– You can change this global key/scale "on the
fly" later.
– Press Home to exit.
Using Global Key/Scale
Once you get more familiar with VoiceLive 3, you
may want to turn Global Key/Scale off in order to
save a different Key/Scale per Preset.
VoiceLive 3 overview
Setting Key/Scale manually
If you are a singer without an instrument, you
may not want to rely on sone external input.
Instead, we'll set the Key/Scale for your song
manually.
For simplicity, let's sing "Happy Birthday" in C
using our Major 2 scale.
You will need to find C as your starting note (un-
less you have perfect pitch – then you are awe-
some).
To set the key/scale:
– If it isn't selected, select the Vocal layer by
pressing the Layer footswitch.
– Press and HOLD the Harmony footswitch until
the Set Key/Scale screen appears.
– Press the Preset up/Preset down footswitches
until the key reaches C.
– If the scale is not already "Maj 2", tap the Step
button repeatedly until the display shows Maj
2.
– Let the Key/Scale screen "time out" and dis-
appear (by not doing anything for a few sec-
onds).
