My yamaha c3 bought in 2005 has a disklavier system, Mark iV pro with prc-100 touch controller (disklavier model DC2M4)
Recently i was interested in playing the disklavier with the iphone app, but the piano was not showing up on the phone. It was connected with lan cable to the same wireless router where the iphone was. When i asked for support from yamaha italy they just told me to use cd player, because the app was not compatible with my disklavier system.
Is that right ? i thought it could be maybe a firmware problem but i cant find any site to download the 4.00
