I had the good fortune to record a live show this week that features a (female)vocalist and a (male)keyboard/vocalist. The kb man played a Triton (yup) and used an Alessis SR16 (my old fav)drum machine. He played manual bass lines (killer chops) under nice Rhodes/string pads, and the ocasional piano sound (weakest in the biz). Sounded AWESOME.

My point is this:
The simplicity and the interaction of the 3 voices (kb/bass/drums) was SO refreshing that I am inclined to keep my Korg i3 just as the core of such a system. The key feel is great, the Rhodes and bass sounds are all there, and although the acoustic piano sound is not so hot (being VERY kind here) I do enjoy the feel of playing a more professionally built kb. After going back to this psr2100, the key feel(and size) is becoming more of an issue with my comfort zone.
I don't expect to take the i3 out too often (if at all), but having a solid, functional piece in the closet makes me happy.... takes away the fright of using the psr on 5pc band gig ( happy? ) and pounding out a Jerry Lee Lewis tune and hearing the plastic crack underneath my fingers. I think the construction of the Korg is top notch, and even though it's a dinosaur ...... Rhodes, bass and drums (my three passions) are ALL THERE.
So - nothing new here...just random thoughts that I thought you might like to hear.

Remember:
Turn those auto arrangers off at LEAST once or twice a set to provide contrast. Even if it's just for a rubato piano intro to a ballade. Make sure you get to PLAY each night, and not just connect the dots.
I'm certain my bass chops have diminished to a degree after useing arrangers. I want to stop that from getting worse.
