I've had my PX5S for about a month now. In general I am happy with the keyboard, and have been able to dial in the sounds I need. I plan on using it at some gigs where I would normally carry around Kronos X 88 in a case. The lighter weight will make a big difference. A couple of things I wish it had: 1. auxiliary output - would be very usefull to me to have another set of outputs 2. recognition of wav filenames for playback (instead of having to be takexx.wav) - this is very dissapointing as I use wav backing tracks. I hope this can be changed in an update. * 3. more stage settings in memory - I would like to have more than 100 stage settings available at once. In general, I find it a really great keyboard and it does compare in alot of ways with much more expensive gear. Dave
