MOTM

I'm new to modular synthesis, just started... I have just completed the 
300VCO (so now I have the MOTM900 and MOTM300 ...)... I'm controlling it with 
a Kenton Pro-2000 from a D-50... Works great... I even had fun using the 
Kenton LFO's to modulate... What fun...

Here's my really stupid (don't laugh) question...The sound is always 'on' and 
remains at the pitch of the last key pressed on the keyboard... Hmmm... 
Should I assume that sound IS always being output by the 300 and that when I 
build the VCA, Eg, Filters, etc I will be able to further control the sound???
