Greetings to all! Has anyone been successful in using the iPhone/iPad ModWheels app with the AP-650? I am presently looking into purchasing the AP-650 over the PX-780 based on achieving better quality piano sound aside from the basic engine provided with both DP. Living in Canada, I cannot yet afford the PX-560 (on top of my wish-list) in its bundled versions. The AP-650 lacks the pitch bend wheel provided with the PX-780. Should I use the AP-650 as a controller with a VST (GarageBand for instance), the use of ModWheels would be a nice-to-have. Finally, I was wondering if the app might have any effet on the internal tones of the AP-650. As you might have already figured out, I am a newbie here Thanks in advance for any advice.
