The PLG150-PF board has 136 sounds including a number of Rhodes, DX-7 tine and Wurly sounds, and it also includes some layered piano/string, ep/choir sounds. I'm ashamed to admit it but I haven't used anything but the acoustic piano voice on the PF lately and I need to go back and try the other sounds out again to see what I'm missing out on! I am still so sold on the PLG150-PF's acoustic piano that I bought a second card to go in my Motif ES 8 - and yes I like it better than the Mo's famed triple strike piano, but apparently I'm in the minority there (Keyboard just gave the Motif ES a KeyBuy award and cited the Mo's native triple-strike acoustic piano as their fav numerous times). I know that I prefered the native Rhodes-style electric piano sounds of the 9000 Pro over the PLG150-PF but I need to review the plug-in sounds again (will do tomorrow night). Gotta love that extra 64-notes of polyphony the PF provides. My second card in the 9000 Pro currently is the PLG150-DX which I use a lot when I sit-in with bands for it's clean classic cut-through tine EP. I also use it for jazz guitar sounds and the occasional pedal steel guitar. I also own the PLG150-VL and AN but don't use them - the AN may wind up in the Mo.

I removed the PLG150-DR drum card from my 9000 Pro because it won't work with the styles at all and using it with my stage midi files would've meant adding sysex commands to all of them - too much work and I wanted the drums to be consistant when switching between sequences and styles. You can read my full complaints about using the PLG150-DR in other posts here. I finally got it to work with the 9000 Pro but I don't recommend it. Mine is now in my studio Motif. I'm still very impressed with the DR's drum sounds and find that they are some of the best and longest real-drum samples I've ever heard, especially in the cymbal area. You can hear what I mean on a page I made that compares the 9000 Pro's very good native drums with the PLG150-DR here:
