My Technics board has a Pianist Mode feature which will allow me to play various over-chords (if that's the correct term ) like D7/A, Fm/G etc. However, this works well for real-time play mostly when I am using piano as the lead - that's why it's called Pianist Mode .

For split-mode play, I am still exploring how to contruct those over-chords using the LH with Fingered Mode only. When I want to experiment further with other instruments as lead, I would usually record the accomp parts with Pianist Mode (to create all the other chords).

Interested to know too how do you all (ze experts) handle over-chords.
