Variable level waveform output on VCO

Variable level waveform output on VCO

2002-01-17 by Roel Steverink

Hi all,

I'm no technician. But I was wondering. What do you think of a new VCO with variable level waveform outputs, like you had on the moog 901 VCO.
I got this I idea when I was plugging a output from my standard VCO and thought, this is always the same, always fixed. Wouldn't I gain a lot more possibilities if the frequency of the waveform could be influenced on the output. Moog called it variable level. Of course it would be nice if you had a knob to accompany it, so you could control that variable level. 
And another idea. A switch between octave and semitones on it as well! Moog had this on 921a Oscillator driver.
I'm curious about your comments.

roel.

You think of a VCA that lowers/rises the Waveform level in proportion to
the note that is played? All you need is a VCA that is controlled by the
keyboard voltage.

This is more elaborate and costly you might think, since you need high
precisision components. We talked in synth-diy maillist about this some
time ago.

hi roel,
i'm not sure what you mean...you can have variable
level for each waveform by using a mixer after the
vco!!!also,what do you mean by"...A switch between
octave and semitones on it as well!..."a switch for
octaves already exists...
synthfreak
p.s.:i was speaking to dieter doepfer the other day
and he reffered to the a100 modules leds as"RED
LEDS",so...i'm not gonna tell you 'told you so..."
