The MAXX is the last thing handling the output signal and with powered speakers only, it acts the same as being adjusted in an external mixer.

No doubt about it Don, your settings bring out some very nice sounds on my Pa3X too.

The Pa900 does not have the MAXX section, although it does have similar adjustments and I never used them with the internal speakers, but I sure do with my external speakers and it makes the Pa900 sound much more alive.

And - with the external speakers, the two keyboards sound amazingly alike.
