Manuel, yes....all true actually the Genos is more advanced...as it has 3 switches for articulation on the SA2 voices and Ensemble voices. Makes sense as the ELS-02C (latest) came out in 2014, Genos 2017. That's why I think the Genos TRX approach could be totally awesome!

Bill, You can buy an expression pedal from Musicland with L and R side switches...just connect them to the Genos (or other).
I even think a second pedal can be used on a Genos, if you use a Yamaha MFC-10 foor MIDI controller.
