New thoughts......
I have a MIDI version of Bach's TandF.
Using studio 2 app the bass and treble clefs can be displayed and then saved as two separate MIDI tracks.
Now convert each to MP3 and save bass and treble clef versions as stereo on left and right channels and save to CD.
Now play each track via 2 Schmitt triggers switched alternately at 30 hertz.
(notes in a chord played alternately at 30 hertz sound very much 'chordal'.)
All this should enable tesla to handle chords, with increased clarity, spread over the bass/treble as they are handled separately.
ALTERNATELY, split my two GU81 into two separate teslas (new pri and sec coils required), and play bass clef though one and the treble clef through the other.
