A Fixed Key Works Also
If your harmony processor shows a check mark in the
Scale Select column in the Compatibility Chart, you can
explore the Key footswitch functions discussed below.
You will likely find that the harmony in some songs just
sounds better with a fixed, non-adaptive scale.You may
prefer the sound of the harmony “clinging” to the main
key more or you may just want to sing a song without
playing your guitar. In this case you can input a fixed key
and scale using the Key footswitch. When you set the
key and scale as described below, this will automatically
turn HarmonyControl off to “freeze” these values. For
you VoiceLive users accustomed to tapping in key and
scale with footswitches, the following is truly a bonus!
To set a fixed key and scale:
1. Load a Scale harmony preset in your processor.
2. Tap the Key footswitch, its LED will light. “S2” will indicate
that scale variation 2, the default, is selected.You can tap
the Key footswitch to cycle through the three scale
variations, S1, S2 and S3 if you need to.
3. Play a major or minor chord on your guitar that
corresponds to the key of your song. Upon receiving the
chord, the Key and On LEDs will turn off automatically
and the key will be sent to your harmony processor.
4. To return to Adaptive Scale mode, press the On
footswitch.
If you don’t know the Key to your song:
1. Load a Scale harmony preset in your processor.
2. Press and a hold the Key footswitch for two seconds, its
LED will flash. “S2” will indicate that scale variation 2 is
selected.
3. Play through the chords of your song while singing until
the harmonies sound correct.Try tapping the Key
footswitch to cycle through the three scale variations to
find one that works with your song.
To reset scale recognition from chords, cycle the On
footswitch so that it goes off and on then play your
chords again.
4. Press and hold the Key footswitch for two seconds to
set the learned key and scale.The Key and On LED will
turn off.
5. To return to Adaptive Scale mode, press the On
footswitch
