Welcome 3dsmatt!
Yes, you came to the right place
The short answer is yes! There is no reason you cannot get wonderful traditional sounds out of the PEK without a barrage of effects. I think it excels at delicate analogue sounds as well. You will not be disappointed with the raw sound.
For an alternate to what you may have already seen or heard, I'll recommend listening to some of the music posted on this forums PEK music thread. You will hear the traditional sounds like plucked strings, short keys, flutes, horns, strings, choirs pipe organs...and the list goes on. There's a lot of forum users here that'll be able to point you to other good examples. I'm going to nominate Sacred Synthesis pipe organ patches for huge sound with minimal effects.
