I do not use registrations at all .
If I play a sequence I use 01 unison .
Setting 02 is for right hand . Let me give you an example . Ramblin Man is the example .
I use setting 02 for right hand . I play the chords and sing the harmony's .
If I release my chord , I have solo voice .
If I need unison I can change the setting to 01 with a footswitch or by hand hand .
All I need are 3 settings ( for my needs) . One for sequences , One for Styles and one Setting that allows me to play the chords and harmonize via my chord structure ! dano
