As someone pointed out in another post, the great art of DSP is not 
to draw exact replicas of the geometrical functions we are naming 
the waveforms from. That would be sounding quite horrible with lots 
of alias. The reason is that in the digital domain we are working in 
a band limited world, and the limiting that is done automaticly in 
analogue equipment from diodes, capacitors etc we need to take care 
of by smart methods of implementing the digital algorithms. 

The SWAVE machines use techniques that will give no alias 
whatsoever, which is kind of special. They might not look like you 
might expect them to, but they will hopefully sound very good, even 
if you are playing the highest note available. By using these other 
techniques we get sounds that should be more pleasant and 
interesting to listen to. Try sampling the output from an analogue 
synthesizer. The waveform you find there will also look distorted in 
some way, even though they sound good. It's when you sample a 
waveform and it looks like you expect it to you should be alarmed. :)

However, to get a better insight what the original waveforms sound 
like you should start by disconnecting the filter follow for the 
high pass filter. Go to kit->assign->key and change the hpf switch.

Hope this helps...
