Overview: maths is an analog computer designed for musical purposes. Amongst other things, it will allow you to: 1. Generate a variety of linear, logarithmic, or exponential triggered or continuous functions 2. Integrate an incoming signal 3. Amplify, attenuate and invert an incoming signal 4. Add, ...

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 indic...

Rise/ fall/ vari-response log expo linear these controls shape the signal that is output at the unity signal out and variable out for ch. 1 and 4. The rise and fall controls determine how fast or slow the circuit will respond to signals applied to the signal in and trigger in. The range of times is ...

Signal outputs there are many different signal outputs on the maths. All of them are situated at the bottom of the module. Many of them have leds situated nearby for visual indication of the signals. The variable outs these outputs are labelled 1, 2, 3 and 4 and are associated with the four attenuve...

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 than av...

Patch ideas: analog voltages, low frequency oscillators typical voltage controlled triangle function (triangle lfo) set ch. 1 (or 4) to cycle. Set rise and fall panel control to noon. Set ch. 2 attenuvertor to noon. Patch sum out to both control input. Apply desired frequency modulation to ch. 3 sig...

Patch ideas: analog voltages, triggered functions/envelopes voltage controlled transient function generator (attack/ decay eg) a pulse or gate applied to the trigger in of ch. 1 or 4 will start the transient function which rises from 0v to 10v at a rate determined by the rise parameter and then fall...

Patch ideas: analog signal processing, voltage maths! Add, subtract control signals apply signals to be added/ subtracted to any combination of signal in ch. 1,2,3,4 (when using ch. 1,4 rise and fall must be set to full ccw, and cycle switch not engaged). For channels to be added, set attenuvertor c...
