Stefano,
Please answer one question for me..Based on all your testing...How good are the instumental (Orchestral) voices on the M50? The real question I guess is how are the samples?

The original M3 AND the PA2/PA800 have quite a few really bad samples. Varying vibrato's, different timbres per sample, weak levels in upper ranges, white noise on a lot of the upper ranges strings... etc

Thanks,
Lee
