Hi, everyone. Thank you very much for the extensive suggestions and comments. I'll try the various options so far recommended (and am, of course, open to new ones!). However, a lot of what has been suggested will probably go beyond what my knowledge of MIDI, disklaviers, etc will allow me to comprehend and/or implement. I probably should get a disklavier expert come and look at my setup. However, I live in Rochester NY and, in spite of having the great Eastman School of Music right in my neighborhood, there seems to be a shortage of Yamaha-certified disklavier technicians in the area. Does anyone have a recommendation? Thanks again!
