This post inspired my other post about using pedals to control the bassline.

Bachus is right, these Yamaha Japan organs have a different feature set with some important features missing. I downloaded manuals for the D-Deck and the Electone EL-C. As best as I could tell, neither one has the "AI Fingered" chord recognition mode that appeared on these shores with the first Tyros.

Recall that the intent of AI Fingered was to give a player more control over the Bass (with simplified fingering and within a compact split of C1 to G2.) Perhaps Yamaha assumes that with two manuals and bass pedals, players would have no need of that mode.

Interestingly... if I plug a pedalboard into my Tyros and configure the MIDI properly, it works just like an old school Electone's Auto Bass Chord. Pressing a pedal will usurp control of the arranger bass. However, the bass reverts to the root of a played chord when no pedal is pressed. A tidy implementation!
