Hi All, New to the forum, and new to keys. Have a new PX-5s, and am a bit overwhelmed. I'm sure what I need is lot's of time to goof around, but I have just a couple questions. Also, I need to say that a huge part of my decision to go with the PX-5s is down to Mike Martin. That guy popped up everywhere while I was doing research, and his level of engagement is just really impressive. So if you're out there Mike, a straight line can be drawn from your efforts to my buying this product. At any rate, here's my issues: *When I operate dial k4 while playing, I hear a slight but pronounced popping in the headphones. This is across all tones, stage settings, etc. Bad pot? Should I take it back? Since I'm new to the instrument, I don't know what I should be expecting as far as tolerances. *Hex tones Synth OSC and Filter OSC seem to have lots of white noise behind them. Is that normal? * The several of the Hex EPs seem to have a pronounced key-up sound, even if the key-down tone has decayed to silence. Sounds quite strange. Is this a feature? Thanks for the help, Mike
