The P5 has been my dream synth since I was old enough to, well, have a dream synth. I'm old enough now to be on my 3rd Prophet 5. It's great having a slick, reliable version at hand, always ready to rock. Of all the new rev4 features, I use... MIDI and... maybe that's it. I rarely use velocity or AT. The Prophet was built so thoughtfully first time around and it works so well as it is. I'm lucky to have a range of other gear to do other whatevers with, but I've never felt the P5 lacking for anything. Not even for extra voices! I played piano before I got my first 5, but my hands adapted immediately to having no more than 5 voices to work with. It's fab that people have the option of grabbing a P10 or upgrading their 5s, but for the way I do music, the Prophet 5 is perfect and sits at the center of almost everything. Just as I never wish my cat also functioned as a 3-D printer, it's never occurred to me to wish the new Prophet 5 could also do... things it doesn't do.
