Xpantastic!

Hi,

I had to go through my patches to find some patchs using quatize.
It seems AFAIK the quantize function is most useful when modulating 
the frequency of a VCO. As you point out it is hardly noticable on 
other modulations.
You can quantize the lag modulations going to the VCOs  repete many 
times to get a large range. This gives a glisando sound Tomita used 
on Planets. " Turn the regular lag off in the main VCO page"
I have also found it useful to quatize square or tri wave LFOs 
modulating the VCO frequency. You can get a stepped series of notes 
in halfsteps.
If you feel ambitious try several LFOs all set to the same frequency.
Then adjust the re-trigger different for each LFO. This creates a 
programmable arpeggio.    
I remember using it once on a modulation of an LFO rate to sync 
things together. But I can't find this patch.  

Hope this helps

Karl
