I've definitely heard retold stories of Arp Odyssey's being returned  
as broken because the VCA slider was raised. It ranks alongside  
stories of monosynths being sent back because they only played one  
note at a time when you tried to play a chord. Rick Wakeman still  
tells that story of being given a "broken" minimoog. Though  
admittedly the initial gain concept requires some actual knowledge to  
grasp and use. As for "hold" etc. that a couple people mentioned.  
It's well known that numerous musicians resorted to sticky tape,  
weights, knives, etc. to get their synths to play drones for what  
it's worth. I would think a special "hold" function sometimes seen  
stems partly from Minimoog experiences though the availability of LFO  
to VCO modulation practically requires a pot imho.

To me, I quickly grasped the concept. The vast majority of LFOs swing  
positive and negative. VCAs just work with positive values. If you  
want to patch an LFO to control the the VCA you will need one with  
initial gain if you want to hear the whole wave rather than the  
positive portion then nothing for a half cycle.  If you don't have a  
routing for LFO to VCA to begin with then I can follow why a designer  
would leave it off.

I agree with monotimbral synths. Though in the 90s before modulars  
were common again, I started reading about people sharing stories  
about playing Oberheim Xpanders without the keyboards. Being matrix  
modulated and multitimbral meant you could get some complex layered  
self playing patches going. That gets me thinking, if only I had a  
mod to route the output of one voice into another. That would really  
xpand it's potential... but anyway...


I just thought I'd share what I've heard on the subject. I do wonder  
how, without a work-around, like a mixer with offset or a separate DC  
source one would work with LFO to VCA on a little system and hear the  
whole sweep of the LFO.
