Kurzweil PC4

Ten years ago, I ordered from the same Thomann its predecessor the PC3k serie. I purposely did not "bathe" myself into Youtube videos to still be surprised as I trust the brand since I know since the K2xx time.

Main difference is the weight, nearly twice less due to the plastic instead of metal. The screen is much better, however the power supply is not good quality to say the least. Bit disappointed not having UK supply thankfully I had a convertor. The power switch button lack firmness. But I understand the PC serie is not the brand flagship anymore but the Forte is. Speaking of Forte if you re more a pianist I would recommend this model or the SP serie otherwise you would be disappointed by the keybed type. Otherwise for synth players like me it is ok.

The FM engine is really a nice addition without hesitation.

Great sounds, great keyboard (I was unsure about it till first touch), great quality.
Pros: weight and size!, sliders in organ mode, overall sound quality and quantity, multifunctionality.
Cons:
What I really miss compared to my old K2000 -
1) independent output level (on a PC4 A and B output levels unfortunately go through the same Volume slider);
2) actual Lock of parameters on Global Mix page (f.e. I lock the Pan of channel at 0, but after turning device off/on it shows 64);
3) The Tempo knob, if touched in Song mode while sequencer is playing, resets Pan, Fx, Volume state of tracks. I wish it could affect only tempo with no undesired artefacts.
