Thank you all for contributing with answers to my questions.

To refresh my memory I listened to a few sound samples of the PA1X pro:

First of all I think the PA1X doesn't have anything noisy about it! A few korg synths/keyboards have been a little noisy in the past, I have not yet felt any such with the PA1X. It has a soft punch and what I want to do with the sound is to just raise the volume and add a lot more mids to it alternatively add a good compressor and set the low and high a little higher, simply just to uncover the quality potential of those sounds! In my opinion several voices sound too dark in my taste, which makes me longing for a compressor with it.

I adore the slap bass and the kick drum in the PA1X, very useful in my opinion and I think you are able to get some sweet pad variations from it as well. That's also very useful!

Now I have to check out the TC helicon products.
