Detailed Operation
b) Set the GLOBAL NATURALPLAY parameter
in the SYSTEM tab of the Setup menu to
SCALE. This will disable the auto input sensing
feature of NaturalPlay.
To set key using the Switch3 footswitch:
You can connect the optional Switch3 footswitch
for direct access to Key setting during perfor-
mance.
1. Connect the Switch3 to the PEDAL input.
2. Set any of the footswitches to SET KEY in the
SWITCH3 tab of the Setup menu.
3. Load a harmony preset to sing through.
4. Tap the footswitch you assigned to Set Key in
step 2.
5. Note the prompt in VoiceLive Rack’s display
and use the footswitches to input your key.
The previous assignment of the 3 footswitches
will temporarily be replaced by the key setting
functions.
6. The key will become active immediately unless
you press the Cancel footswitch.
If you have a guitar connected, this makes key set-
ting with Switch3 even easier. Simply play a major
or minor chord that you want to use as the key
then tap the Set Key button on the footswitch.
The chord you play will be recognized automati-
cally.
Note that the Key you set is global so you can
try other presets with your song without enter-
ing Key again. To configure presets so they can
save different keys and scales, set the GLOBAL
KEY/SCALE parameter in the SYSTEM tab of the
Setup menu to OFF.
If you’re lucky the first time, you’ll be rewarded
with musically appropriate Harmony and/or
Hardtune effects musically following your whole
chorus or song. If not, you can try the following:
tune-type processing products.
Briefly, all of the chords in an entire song and your
melody can belong to a single major or minor
“Key”. When the match of Key and song is cor-
rect, fixed key is harmony is nearly indistinguish-
able from recorded harmony. There are limita-
tions however:
• Fixed Key harmony works for many, but not all
songs.
• Fixed Key works best with 3rd harmony inter-
vals; adding the 5th (interval: Higher) reduces
the number of compatible songs.
• The terms “Key” and “Key and scale” can be
used interchangeably.
You should be singing with musical backing and
stay true to a A=440Hz reference. This could be
a CD or other musicians. Choose a simple song
to start with. Determine the Key of your song;
this is often the first or last chord in a song with-
out extensions. For example G Major is a valid
Key, Gm7b5 is not.
To set key from the front panel:
Both harmony and Hardtune use the same key
and this is set in the HARMONY edit tab.
1. Load a preset with Harmony active. A good
one to start with is #3 CLOSE UP 3RD.
2. Hold the Harmony button.
3. Set the KEY and SCALE parameters on the
top line* to the key of your song.
* If these parameters are not visible, the Natu-
ralPlay algorithm in VoiceLive Rack has recognized
input from either the AUX IN, GUITAR IN or
MIDI inputs and has configured itself to derive
guidance from that input.
In this case you can:
a) Cycle the power off and on and ensure no
connections are made to the inputs noted
above.
