Limited warranty: 3 about this manual: written by tony rolando and walker farrell illustrated by w.Lee coleman make noise warrants this product to be free of defects in materials or construction for a period of one year from the date of purchase (proof of purchase/invoice required). Malfunction resu...

The make noise contour is an electronic music module requiring 38ma of +12vdc and 17 ma of -12vdc regulated voltages and a properly formatted distribution receptacle...

5 overview contour is a 4 stage function generator derived from our 0-coast synthesizer. It is designed to create control voltages to drive the dynamix, moddemix, and other fast vcas, vcfs, and more. The contour takes inspiration from the original loudness contour circuit of the minimoog, which is p...

6 panel controls 1. Gate input: gate applied to this input initiates the circuit. The result being a 0v to 8v function, aka envelope. Range 1.5v or greater with gate width determining sustain time. 2. Onset panel control: sets the time it takes for the voltage function to ramp up to maximum level. C...

7 getting started to initiate the contour function, patch a gate to the gate input. Any signal 1.5v or greater in amplitude works to start the event. Note: that the width of the gate is also very important as it determines the sustain time. Onset determines the amount of time the contour takes to tr...

8 getting started (cont’d) with the sustain setting anywhere between minimum and 3:00, the contour generates a 4-stage function that, when used to drive the dynamix module, produces the classic “adsr,” or attack, decay, sustain, release amplitude envelope, as popularized by the east coast synthesis ...

9 eon and eoc eon (end of onset): this gate output goes high after the onset portion of the contour is finished, and goes low after the decay portion is finished (figure 6, 2). It could be used to initiate events elsewhere, such as triggering a channel of maths by patching to the trigger input. Or p...

10 patch ideas analog/control voltages: voltage controlled transient generator (attack/ decay envelope) set sustain panel control full ccw. A gate applied to the gate input starts the transient function, which rises from 0v to 8v at a rate determined by the onset parameter, then falls from 8v to 0v ...

11 patch ideas (con’t) typical voltage controlled triangle function (lfo) patch the eoc to the gate input. Set onset and decay panel controls to 12:00. Apply the desired modulation to both cv inputs. Setting onset and decay parameters further clockwise lengthens the cycle. Setting these parameters f...

12 patch ideas analog/control voltages: typical voltage controlled pulse (clock, lfo) same as voltage-controlled triangle function, only the output is taken from eoc or eon. Using eon, the onset parameter adjusts the frequency and decay parameter adjusts pulse width and frequency. Using eoc, the opp...

13 patch ideas analog/control voltages: the new vactrol free bongo: set up a vco for two-operator fm by applying a sine wave to its linear fm input or using the dpo’s fm bus and patching the resulting waveform to dynamix’s signal input. Set the associated attenuator to 4:00. Patch an exponentially-s...
