Special thanx to Tadao Kikumoto and Don Buchla for their original and inspirational circuit designs.

Installation:

The Make Noise MMG is an electronic signal generator requiring 50mA of +/-12V of regulated power and
properly formatted distribution receptacle to operate. It is designed to be used within the euro format
modular synthesizer system.

Go to http://www.doepfer.de/a100_man/a100t_e.htm for the details of this format.

To install, find 12 HP of space in your euro-rack synthesizer system, confirm proper installation of included
power cable on backside of module (see picture below), plug the 16 pin end power cable into the euro-rack
style power distribution board, minding the polarity so that the RED stripe on the cable is oriented to the
NEGATIVE 12 volt supply line. This is USUALLY at the bottom.

Please refer to your case manufacturers’ specifications for location of the negative supply.

Proper installation of included power cable on module.
Please note the RED BAND.

Overview:

The MMG is a Vactrol based Voltage Controlled Filter and Low Pass Gate using our QMMG core. The MMG
bridges the Far East and West Coast synthesis styles by allowing for highly resonant acidic squelch and
organic, percussive animations to be programmed simultaneously with a single module.

The AC coupled Input has an attenuator to adjust signal levels. An un-attenuated DC input is also offered as
this was the type of input utilized on the original QMMG. Together these inputs allow for mixing audio signals
or combining a control signal with an audio signal to yield asymmetrical behaviors in the circuits that follow.

The MODE circuitry allows for smooth Voltage Controlled sweeping between Low Pass and High Pass
responses.

Voltage Controlled Q Factor yields everything from smooth to aggressively clipped resonances while an
Automatic Gain Control circuit keeps signal levels under control at high resonance settings. The AGC is
user-adjustable, see the calibration procedure on page 11 for details.

An ACCENT input is provided for programming X0X style punch and a STRIKE input allows for LPG style
bongo plonks (René X and Y gates work well at these inputs).

The MMG is a 100% analog filter for musical applications and is not suitable for laboratory use. The MMG
utilizes Vactrol based gain cells where voltage control is required. Therefore the MODE, FREQuency and Q
controls will all have a unique response that is slower than the typical solid-state filter circuit.
