Hii, I'm new sorry if it seems like I'm posting loads of threads but I guess I joined here to get proper advice off people who actually know what they're talking about, so I'm going for it haha.

I recently purchased a Korg sp-250 as I'm currently doing my grade 6 piano and I needed something a little more substancial to practice on. It's pretty good but because it was second-hand (only because the guy who had it before said it was too heavy to play gigs with, and he is too old to lift really heavy stuff or something)
anyway, it was left in a kind of storage room that was a bit cold so when I first played it some of the keys didn't work. My dad said the cold can effect electrics but within 24 hours all of the keys worked fine and have done ever since.

Now my point is; sometimes when I play the notes they seem to cut short as if I had played them staccato. Even when I don't press the sustain pedal usually the note lasts a little bit. I didn't know whether this was my sloppy playing not being used to a digital piano or whether it was something to do with it being second-hand, the shop said I could change it for the one in the show room but I don't know whether that would be more scratched and stuff. Does anybody know if it's just the way it is or whether it is a fault or not?
I suppose it's hard to tell without actually playing or hearing it.

Sorry for the essay, thanks.

I'm not an electrician but I do have a digital piano and it shouldn't behave like this.
It rather sounds like a dodgy connection or cable, but even if not, I should swop it if you have the chance. Better a slightly battered instrument that works properly than one that sounds like a bad phone line.

Ah cool, thanks for taking the time to read all that. I think I will change it then. I'd asked an even amount of people and got a 50/50 on either keeping it or taking it so I needed an extra person to sway my desicion haha. I think I would regret it if I didn't change it anyway, thanks

Hi,

I've got one of these, paid about 385 notes for it new. They're cheap and cheerful, although Korg do produce some pretty good kit, at the higher levels of musicality. I use it for messing about with compositional stuff on my Apple-Mac. It is not, i.m.o, a serious keyboard and thankfully I have an acoustic baby grand for classical repertoire. However if you need an 88 full size keyboard for work in Sibelius or Finale then it's OK and a lot better than some of the the cut down midi keyboard controllers like the M-Audio radium 49.[I have one of these also] The problem you mention is probably due to latency, the drop out/ decay time of the audio signal in a cheap keyboard is well known c.f Casio, low end Yammys et al. It's got nothing to do with electrical connections vis a vis 13amp sockets and cables
