I don´t understand a company is using such cheap components in such a, in most cases really advanced, keyboard instrument. The pitch bend mechanism and electronic circuitry is so important for a synth´s tuning. Unbelievable,- none of my other keyboards, all from the past, introduces such crappy behaviour. My PC361 is a studio instrument, never transported,- and it´s tuning wise sensitive on shocks and vibration caused by playing while it sits on the keyboard stand. The Alpha/Taiwan pots are crap and the other component I suspect is the trimmer-pot for pitch-bend wheel center position. When you´re one of these players using +/- 2 semitones PB-range only, you probably don´t recognize the issue early. The larger the PB range is, the earlier the pot fails ! With the PC3, it really depends on if you´re a synth player doing much pitch-bending and which PB range you prefer. Never ever had this w/ any other keyboard I buyed within 4 decades. When you replace PW or MOD pots w/ original components, you´ll have to do it every 1 1/2 years. Have you ever experienced this behavior? Does it require a hardware replacement or is there a software fix? BTW, I have installed the newest OS in it, and didn't change anything.

Again, only changing the program ends the odd modulation behavior, only temporarily. And that's when I noticed that the modulation wheel, when my PC3 is hooked, never goes below +/- 30% and is always moving a bit up and down. As you know Reason depicts graphically a representation of the pitch and modulation wheels of the controller keyboard. And then, when using Reason, I think I saw why. Over Midi, Omnisphere and other softsynths had the unwanted modulation applied in the same way as with the Kurzweil's own synth engine. i thought this was a bad LFO, but then I tested it with MIDI. The only way to stop that unwanted modulation is to change program. It also happens after busy passages that don't involve sustained notes - say, after 15, 20 seconds. Alternatively, the same thing happens when I touch the modulation wheel to any degree, it just fires a heck of vibrato, that doesn't stop even when the wheel returns to "zero" position.

On local mode, I started noticing that a considerable amount of unwanted modulation (vibrato, most times, but really, it seems to be any modulation source assigned to the Mod Wheel) is being applied to the sound after a key is depressed and sustained for more than around 10 seconds. My PC361 started acting weird out of the blue days ago.
