The sample sizes are really extremely impressive. But consider that it is only 2 part multitimbral and 8/16-voice polyphonic.
Yes, but thats not because the limitations of the sample player, but because of the limmitations of the analogue filter.. in an analogue filter, each note played gets its own filter, or 2 filters in case of a stereo sound...
Using todays technollogy to kill nearly all sample size limitations in a hardware instrument is a huge step..
