Performance Tips & Techniques; Processing External Audio - Moog Minimoog Model D User Manual

CONTROL INPUTS
V-TRIG IN
This 1/4" jack can receive a standard V-Trigger from other electronic instruments. It uses a standard
V-Trigger connector in place of the S-Trigger and Cinch-Jones connector used on the original
Minimoog Model D. A trigger signal received here will cause the Contour Generators to fire and will act
as a keyboard gate.
MOD. SRC. INPUT
A varying control voltage signal connected to this input jack can be used as a modulation source.
Inserting a standard 1/4" cable into this jack breaks the normalled connection of the Noise modulation
source, and any external control voltage applied will take its place. With no cable connected, this jack
remains normalled, connecting the Noise send to the MOD. SRC. input, and NOISE can be selected as
a modulation source.
TIP: This jack is equipped with a TRS (Tip/Ring/Sleeve) connector, which allows it to also function as a
send for the Noise Generator. With WHITE NOISE selected, the modulation source becomes Pink Noise.
With PINK NOISE selected, the modulation source becomes Red Noise.
PERFORMANCE TIPS & TECHNIQUES
Even with its streamlined control panel, the Minimoog Model D remains a deep and versatile instrument
for audio synthesis. Here are just a few examples of how the Minimoog Model D may be used in
interesting and perhaps unexpected ways.

PROCESSING EXTERNAL AUDIO

Using a Moog Ladder Filter to process external sounds can lead to extremely creative explorations. Try
filtering another keyboard, a guitar, found sounds, etc.
1. Connect the external audio source to the Minimoog Model D via the EXT. SIGNAL INPUT jack on the
Top Patch Panel. (The level is set using the EXTERNAL INPUT VOLUME knob on the MIXER panel.)
2. Be sure the blue rocker switch for the EXTERNAL INPUT VOLUME is ON. For now, set the other
blue rocker switches to OFF so you can isolate the external signal.
3. In order to hear the signal being filtered, the Contour Generators need to be triggered. This can
be done by touching the keyboard, or by using an external trigger from a drum machine, additional
synthesizer, etc. Ensure the orange FILTER MODULATION rocker switch is set to ON or the Contour
Generator will have no effect on the filter.
4. Using the Modulation Wheel can introduce more complex filtering effects. For example, set the
black NOISE/LFO rocker switch to LFO, set the orange FILTER MODULATION switch to ON and
rotate the MODULATION MIX knob fully clockwise.
5. Next, pull up on the LFO RATE knob to select a square wave.
6. Finally, as the external source is playing, hold down any note on the Keyboard and push the
MODULATION Wheel forward to create a pulsed filter effect. Adjust the LFO RATE, FILTER CUTOFF
FREQUENCY, and EMPHASIS knobs accordingly.
