One thing I just thought of Dave, did you try the Harm M in manual mode?

Yup - it still has that weird sustain deal going on. Manual mode it too tricky unless you can transpose the affected notes to suit the song. I use it on the s-950 sometimes .... it's a acceptable workaround for now, but it's not where I need to be. PA900 should be out in early Fall (I hope), so I'll experiment with other options around the audio input scenario - the vocals are number one priority in my world, the rest is gravy.

Well, apparently, all Korg needed to do was put speakers and a TC harmonizer in the unit and they got me!
I've had the PA900 on the stand for about an hour and I'm trying to get to it as much as I can, but we're also trying to entertain 8 1st graders at a pool party in what looks like a crappy, rainy dy! Grrrrrr .... Sigh.

First impressions:
key feel - excellent
look - a tad cluttered, but easy to adjust to (the 3x is just so perfectly laid out)
speakers - not as powerful (at least so far) as the Yamaha, but I think with EQ and balancing it may improve. Seems quiet at first
tones: AWESOME
features: almost nothing is missing - the 3x sliders are easy enough to use in the touch screen, great C/S, lyric display, CD-G file readout etc
screen: seems easier and more responsive with less pressure than the 3x - like it
size/weight - BEAUTIFUL - sleek, attractive (still wish it was black, but the silver is cool)
mic - it's not the crystal clear high end sound that the 3x has, but that may just be the speakers settings (comp, eq, etc) ... I'll hook up to PA later today

Overall - I think it's a winner. The basic design is very familiar, and it will go on it's maiden voyage to the Jersey Shore this Monday. I'll have LOTS to tell on Wednesday when I return!

Stay tuned ..........

Dave,

I should have mine Tuesday, but I will be happy to see your review after several days of use.

Some demos too by you if you will please.

Thanks, Dave, disappointing to hear that about the speakers, I was hoping for better.

I'm not jumping to conclusions yet because there are such deep menu choices to make edits. It may well be possible to turn off or adjust the gates and compressors and master EQ to get a cleaner signal. As of right now - as soon as I play a note on the kb, the mix takes the signal in and I hear the gate open .... annoying, but maybe fixable.

Dave, have you installed the OS release 1.01? there were some bug fixes in that apparently.

Graham ... I still have to do that - it's too sunny out today ... need some pool time with my redhead!

If "the redhead" is a loved one, congratulations on your priorities!

She's been a treasure since the 6th grade - we just started getting closer about 6 months ago. Priorities are in order!
