Mock-Up Design for a new Moogerfooger CP Unit w/ image
Posted: Mon Jan 29, 2007 4:57 am
So I thought I'd try making a mock-up of new CP moogerfooger, in light of the modular possibilities starting to arise from the wake of MF-107 coming out. This fooger would add essential modular functionality plus a bunch of fun features you really only get with a modular set-up usually. And yes, I'm aware there's already a ring mod in the fooger line..two is better.
(if image is not displaying, click here)
Here's a quick run-down of the mock-up:
---------
~Envelope Generator: Voltage generator that changes over time, use with pitch/gate dynamics/filters etc.
Logarithmic/Exponential switch: Switches between two different response slopes. A neat feature I wish more envelopes had. I realize this switch type might be a little too big, so another option would be to use something more like the A-B switches on the MF-105's.. either way this would be rockin to have on an ADSR.
Attack: Controls attack time
Decay: Controls decay time
Sustain: 0 - 5v
Release: Controls release time
Gate: Incoming gate signal starts the envelope.
Pedal IN: Controls voltage of overall ADSR signal.
+OUT: Positive envelope out.
-OUT: Inverted envelope out.
--------
~VCA: Allows control of the amplitude of a signal. Used in conjunction with envelope generator to shape dynamics.
DRIVE: Sets the output level of the amplifier.
ENV IN: CV Input for dynamic amplitude control of the drive knob. ENV OUTs, Pedal IN, etc would all apply here.
IN: Audio IN
OUT: Audio OUT
--------
~CLIPPER: Clips the tips of a waveform (top and bottom) to create new waveforms.
LEVEL: Controls voltage level at which clipping will start.
Pedal IN: Allows for CV control of the LEVEL knob.
IN: Audio IN
OUT:Audio OUT
--------
~RECTIFIER: (description taken from synthesizers.com) The rectifier has the effect of taking the bottom of the waveform (the part below 0 volts) and flipping it to the top. When a sawtooth or ramp wave is used as an input, the output will become a triangle wave at 1/2 the frequency which is level shifted. When a triangle waveform is used as the input, the output will be triangle at twice the frequency. When a sine waveform is used as the input, the output will be a waveform with unusual harmonic content at twice the frequency. When a square or pulse waveform is used as the input, the output will be only be a small spike which has minimal usage.
Patching the output of the clipper into the input of the rectifier can create a whole new group of waveforms in which every other cycle is clipped.
neat huh?
IN: Audio IN
+OUT: Rectified Audio OUT
-OUT: Inverted Rectified Audio OUT
-----------
~RING MODULATOR: Audio signal X and Y are multiplied, creating an output that contains the sum and difference of the input signals. A very simple but lovely version of MF-102.
X: Audio IN
Y: Audio IN
OUT: Ring Modulated Audio OUT
--------
~ATTENUATOR: Same as CP-251's, these cut down the strength of a voltage signal.
Knobs adjust the attenuation as normal -5/0/+5.
IN: CV IN
OUT:CV OUT
------
So there ya have it. I'd really dig something like this for my moogerfooger rig. How about you?
