I have found my perfect combo, Pa4x and a Sx900, they cover my every need. Both have a large community for information and sharing the things we know. These two keyboards should not be compared, they are both good. Amen! They cover two different areas, trying make them do the same type of job is a no, no.

This is my third Pa4x, without the Sx900 I would not be satisfied. If I choose to work like an artist who painting a scene, the Sx900 is much better. If I am in the mood of working with a strong sound, a system that I can fly through, it is the Pa4x. Setting up a Sx900 for my needs was a breeze --- far more involved with the Pa4x.

A question about two fingered chords VS full left-hand chords. What is the benefit of each? I can finger a chord just as fast – or add an arp. or add a 9th, Maj7th, or pulsate a rhythm – or just support the right hand. Just trying to understand.
But then again I am still typing with two fingers.

Always learning, John C.
