And don't you usually put your VCO through a VCF before the VCA? More outputs? OR seperate pedals, one VCA, one VCO!!! And Moog said they wouldn't do modular again... ;)
murf sliders for the adsr would be really kool. The other aspect i was considering was maybe something similar to what the little phatty has. Sure, it's more work, but if it means a more affordable unit, I'd totally go for it.

Yes! I absolutely loved his idea. Great design, lots of flexibility. I'd totally dig a unit in that format too. :)

cheers

about the post filtering thing, it would only make a difference when the resonance is put up to self-ocsilation, if this was the case you would always hear a drone sine wave even when no keys are pressed.

this would be cool but the traditional VCO-VCF-VCA is a more useful hardwired connection if you ask me, but being able to build you own synth architecture is what modulars are all about

I think when moog say they don't want to go modular they mean recreating the old modular design, i think they would and will eventually release something that will tie all the foogers together as an amazing modular effects/synth machine.

The Pitch to Voltage idea VCO/VCA, is just the thing to do this as well, it would work as a stand alone guitar pedal (admittedly a rather strange one) and it would complete the fooger line


as for the murf slider idea, i was also thinking about this:

imagine the murf lay-out


-----------------------VCO------------------------------
the top row of three knobs could house the VCO controls
- FREQ
- RANGE
- WAVE
with a switch under them to turn the pitch - voltage control on or off
- ON/OFF(ext)

Jacks
inputs:
- FREQ
- WAVE
- SYNC
outputs:
- OUT


----------------------CONTROLLER---------------------------------
The second row of knobs could control the pitch/gate tracking and mix between input and VCO
- PITCH SENSITIVITY
- GATE THRESHOLD
- MIX

Jacks
outputs:
- PITCH OUT
- GATE OUT


------------------------VCA--------------------------------------
the row of eight sliders would have 4 of its sliders replaced a switch that selects the gate, either the gate produced by the input sound or an ext gate, when this is selected but nothing is plugged into the gate input the VCA is left wide open.
- ON/OFF(ext)
The 4 sliders are ADSR
- ATTACK
- DECAY
- SUSTAIN
- RELEASE

Jacks
inputs:
- VCA IN
- GATE IN
- ENV SCALE
outputs:
- ENV


and then all there is left is
- AUDIO IN
- AUDIO OUT

from looking at current foogers i think you could get about 11 jacks on the back
from this idea there are too many but things like sync in and env scale could probably go

getting something like this plus an MF-101 and CP-251 would give you an amazing:
- modular synth
- effects processor
- guitar synth

Moog Dual VCO

Post by eric coleridge » Wed Jun 21, 2006 12:55 pm

Just as a note on this topic, I was wondering if anyone has ever seen or used the Dual VCO rack mount that Moog manufactured in the 70s?

It wasn't a pitch to voltage circuit, but rather two MiniMoog VCOs in a rackmount enclosure like the Moog Parametric EQ and 12 Stage Phaser rack units. It had CV inputs for each VCO, audio outputs, and a multiple. On the front it had controls for tune, pulsewidth, octave, waveform, on/off switch for VCO1, and tune, octave, waveform, sync on/off, and on/off for VCO2. There was an overall volume knob also. It looks pretty great, but I've never heard one. It was an oscillator expander for the original MiniMoog and MicroMoog.

We can only hope this could make it's way out in some form or another. it'd be incredible, and definitely complete the line up.
