The Harmonist is an effect where the amount of shifting is adjusted according to an analysis of the guitar input, allowing you to create harmonies based on diatonic scales. However, occasionally you will want to create a completely custom scale to fit the music you're working with.
The following are the steps to get to the settings needed to customize a harmony scale:
1. Press EFFECT.
2. Using the SELECT knob (knob 4) choose either FX1 or FX2.
3. Using the TYPE knob (knob 2) choose HARMONIST.
4. In the GT-100's Right Hand screen, turn Knob 6 under the parameter: HR1: HARM, until you get to
the USER setting.
5. Turn Knob 8 under the parameter: MASTER KEY until you get to the key you want.
6. Press Page Right to access individual note configuration settings in the scale. There are a
total of 12 scale notes that you can set up with custom pitches on Tabs 3 thru 5.
7. Press: WRITE twice.
