Has anyone tried to use the Yamaha Smart Pianist app to control the new Clavinova CSP150 or CSP170? I have always wanted to obtain a new Clavinova, but up till now, the functions on the CVP and CLP series weren't exactly accesible, as there was no screen reader support on these musical instruments. However, the new CPS series is controled by an app. Before I go and buy the new Clavinova, I would like to know whether the app is accessible with Voiceover. I would likely try it first before buying the instrument, but I am just curious to know whether anyone has already done so. Your input would be appreciated.
