Then it's the Pa1x for you. Durability? Mine's still going strong, and ask Spalding about his Pa1x.
Great, thanks for the info!
I also looked at the Pa1x manual and all Pa50's oscillators (samples/multisamples) are still there (unlike newer pa series), and also there are new ones.
May i ask which version you have (pro or 61 key)?
Thank you all for the replies, very nice community here!
