For predominantly Arranger/Player capability, AUDYA 4 seems to be where you'd want to lean towards. With the new software release (OS 4.2 and higher) most of the bugs and problems experienced in previous OS have been fixed. Also remember that the AUDYA 4 was released way after AUDYA (the 76 keys keyboard which started with OS 2.0a, 2.0b ...etc which were the OS with most of the issues) and it's initial OS was 4.0 - by which time most of the issues experienced in AUDYA were already rectified prior to the AUDYA4 and AUDYA5 being released.

The Midijay PRO won't utilize Audio Drums (complete wave forms) as the AUDYA series and you will have limited ARRANGER capabilities.

Hope this helps in your decision making.

Thanks,
