I'm still new to modular synthesis and wanted to see if someone could 
explain more what the possibilities of the Model 30 are.  It looks 
great but I'm just not sure what all it can do.  The new picture shows 
a patch for a Frequency Shifter (which is one of the 2 things I was 
hoping the Model 30 would be from the beginning, the second I hoped for 
was a vocoder).  Will it be able act as a freq. shifter?  Also what 
digital waveforms will be possible? If someone could enlighten me I 
would really appreciate it.  Thanks.
