Ever since completing the QMMG design, I have felt that it needed a good buddy. A patch pal! Say
hello to QMMG's best friend, MATHS.

MATHS builds on the tradition set into motion in the 1960's by Don Buchla when he adapted the
circuits found within analog computers common to engineering labs, for musical purposes.
Buchla's "Algebraic Processor, Model 257" changed the way music synthesizers utilized control
voltages.
MATHS, a mash-up of the Buchla 281, Buchla 257 & Serge DUSG, continues this great tradition of
sculpting the control signals we use to sculpt our sound signals.

Extra special thanx go out to Kelly Kelbel, Richard Devine &
Aaron Abrams for support in the development of MATHS.

Installation:

The Make Noise MATHS is an analog electronic
signal processor/ generator requiring 60mA of +/-12V 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 20HP of space in your euro-rack synthesizer system,
plug the 16pin 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 NEGATIVE12 volt supply line. This is USUALLY at
the bottom.
Please refer to your case manufacturers' specifications
for location of the negative supply.

Getting to know MATHS

Like its pal the QMMG, MATHS is laid out top to bottom, and with symmetrical features where the
functionality flows from the outside inward. The signal INputs are at the top, followed by the majority of
panel controls and Control Signal INputs at the center and at the bottom of the module, the signal
OUTputs.
Channels 1 and 4 are identical, each being able to scale, invert or integrate an incoming signal. With
no signal applied, these channels may be made to generate a variety of linear, logarithmic, or
exponential functions upon the reception of a trigger, or continuously when the CYCLE switch is
engaged. The Cycle switch also contains a LED which indicates the activity on the associated
channel. One small difference between CH. 1 and 4 is in their respective Pulse outputs; CH.1 having
End of Rise and CH. 4 having End of Cycle. This was done to facilitate the creation of complex
functions utilizing both CH. 1 and 4.
Channels 2 and 3 are identical, each being able to scale, amplify and invert an incoming signal. With
no external signal applied, these channels will generate DC offsets.
All 4 channels are normalized to a SUM and OR bus via their respective OUTputs, so that addition,
subtraction and analog logic OR manipulations may be achieved. Inserting a plug to these sockets
will remove the associated signal from the SUM and OR bus. Channels 1 and 4 have additional
outputs, which are NOT normalized to the SUM and OR bus. Both of these outputs are buffered
multiples of their associated main output. By taking your output from this socket, the signal will still be
applied to the SUM and OR bus.

Tips & Tricks

-Longer cycles will be achieved with more Logarithmic response curves. The fastest, sharpest
functions will be achieved with extreme exponential response curves.

-Adjustment to the response curve will affect Rise and Fall Times.

-To achieve longer or shorter Rise and Fall Times then available from Panel Controls, apply a

voltage offset to the Control Signal Inputs of the associated channel.

-Voltage offsets may be generated by CH. 2 or 3.

-When utilizing the SUM and OR OUTputs, set any unused CH. 2 or 3 to NOON or insert a dummy
patch cable to Signal Input of associated channel to avoid unwanted offsets.

-If it is desired that a signal processed or generated by CH. 1, 4 is both on the SUM and OR busses

AND available as a solo OUTput, utilize the Single OUT Multiple, as it is NOT normalized to the
SUM and OR Busses.

-OR function will not respond to or generate negative voltages.
