Samples are mix of some (barely) refreshed new sounds based on samples from K2500 series.
But rest of the machine shows already limitations where Kurzweil is steeping recently.
Build quality is mediocre and all in all this is one product that seems to be cheaper extraction of K series while higher priced then PC2 range.
I can tolerate K series polyphony when considering splendor of DSP synthesis capabilities,but cost of KME-61 reflects more "lets safe some loses", then genuine new product.
If you long for Kurzweil sound, go with K series, build quality + all Kurzweil really is capable of.
