Getting Started

MATHS is laid out top to bottom, with symmetrical features between CH. 1 and 4.  

The signal inputs are at the top, followed by the panel controls and control 

signal inputs at the middle. The signal outputs are at the bottom of the module.  

LEDs are placed near the signal they are indicating.

Channels 1 and 4 are 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 is engaged.  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 able to scale, amplify 

and invert an incoming signal.  With no external signal applied, these Channels 

generate DC offsets. The only difference between CH. 2 and 3 is that CH. 2 

generates a +/-10V offset while Ch. 3 generates a +/-5V offset.  

All 4 Channels have outputs (called Variable Outputs) which are normalized to a 

SUM, Inverted SUM, and OR bus so that addition, subtraction, inversion and 

analog logic OR manipulations may be achieved. Inserting a plug to these 

Variable Output sockets removes the associated signal from the SUM and OR bus 

(Channels 1 and 4 have unity outputs, which are NOT normalized to the SUM 

and OR bus). These outputs are controlled by the 4 Attenuverters at the center of 

the module. 

Signal Input 

These inputs are all Direct Coupled to their associated circuit.  This means they are able to pass both audio and control signals. 

These inputs are used to process external control voltages.  CH. 1 and 4 Signal Input could also be used to generate Attack/ 

Sustain/ Release type envelopes from a gate signal.  Channels 2 and 3 are also normalized to a voltage reference so that with 

nothing patched to the input, that channel could be used for generation of voltage offsets.  This is useful for level shifting a 

function or other signal that is at one of the other Channels by adding the voltage offset to that signal and taking the SUM 

Output.   

Trigger Input

CH. 1 and 4 also have a Trigger input.  A gate or pulse applied to this input triggers the associated circuit regardless of activity at 

the Signal Inputs.  The result being a 0V to 10V function, aka Envelope, whose characteristics are defined by the Rise, Fall, 

Vari-Response and Attenuverter parameters.  This function rises from 0V to 10V and then immediately fall from 10V to 0V. There is 

NO SUSTAIN.  To get a sustaining envelope function, use the Signal Input (see above).   MATHS re-triggers during the falling 

portion of the function but does NOT re-trigger on the rising portion of the function.  This allows clock and gate division since 

MATHS could be programmed to ignore incoming clocks and gates by setting the Rise Time to be greater than the time between 

the incoming Clocks and/ or Gates.

Cycle

The Cycle Button and Cycle Input both do the same thing: they make MATHS self-oscillate aka Cycle, which are just fancy terms 

for an LFO!  When you want an LFO, make MATHS Cycle.
