Controlled Envelope or LFO 2 Stepped voltages like Sample and Hold Track and Hold Staircase LFO 3 Apply Lag Slew or Portamento to control voltages 4 Modulate backwards 5 Musical Events such as Ramping up or Down in Tempo on command 6 Initiating Musical events upon sensing motion in the system 7 Musical note division and or Flam Indeed the FUNCTION is a direct descendent of MATHS sharing the same core circuit complete with some evolutions 1 since most Make Noise modules have attenuators on the CV inputs the scaling inversion feature has been replaced with dedicated Non Inverted Inverted outputs This is useful as you could have the same signal modulating two different destinations in opposition 2 As FUNCTION is single channel design we included both EOR and EOC There is interesting things you could do with these outputs such as flams see patch tips Much like CH 1 and 4 on the MATHS multiple FUNCTIONs can also be used to program complex functions using EOR and EOC 3 The evolution in the circuit is the HANG input On Gate HIGH at the HANG IN the FUNCTION is stopped dead in its tracks With HANG you can program Stepped LFOs Synchronized Functions using multiple of clock S amp H Track amp Hold Clock Run Stop using EOR or EOC out for Clock and more Tips amp Tricks Longer cycles will be achieved with more Logarithmic response curves The fastest sharpest functions will be achieved with extreme exponent
3. any function If Inverted out is patched to Fall CV IN Log Rise w Expo Fall is achieved By setting Vari Response to Linear combinations of Linear and Expo or Log are possible Envelope Follower Apply Signal to be followed to Signal IN set Rise to NOON Set and or modulate FALL Time to achieve different amounts of Smoothing Take output from Non Inverted Signal OUT Increasing the Fall Time to beyond 70 will result in the Peaks being held for long periods of time EOR and EOC will also indicate activity at the Signal IN A variation on this patch has EOR patched to the HANG IN The Peak is detected and held until user resets by removing patch cable from HANG IN Multiplication VCA Apply positive going Control Signal to be multiplied to Signal IN Set Rise and Fall to full CCW Apply positive going Control Signal multiplier to BOTH Control IN Take output from Signal OUT Patch Ideas Digital Gates Clocking Typical Voltage Controlled Pulse Clock LFO Same as Voltage Controlled Triangle Function only the output is taken from EOC or EOR Using EOR the RISE parameter will more effectively adjust frequency and FALL parameter will adjust pulse width Using EOC the opposite is true where Rise more effectively adjusts Width and Fall adjust frequency All adjustments to Rise and Fall parameters will affect frequency HANG input will act as Start Stop control with the Clock STOPPING when you send a Gate HIGH to HANG FLIP FLOP 1 Bit Mem
4. signal patched to HANG IN Clock signal must be wide in order to achieve S amp H In other words the clock should be HIGH most of the time going low for only a short time An example of this type of clock signal would be to use another FUNCTION or a channel of a MATHS Use the EOC with Fall set to Full CCW and setting the Rise to determine the rate The Rise and Fall parameters determine the range of possible values Track amp Hold Signal to be processed is patched to Signal IN Clock or Gate signal patched to HANG IN Signal will pass to the Signal OUT with the Rise and Fall parameters determining the slew rate When the HANG IN goes HIGH the Signal OUT will be held at the current voltage until the HANG IN goes Low Staircase Function Triggered or Continuous Set up for Typical Voltage Controlled LFO see above Patch clock signal to HANG IN Clock should be at higher frequency then that of the function

8. ial response curves Adjustment to the response curve will affect Rise and Fall Times To achieve longer or shorter Rise and Fall Times than available from Panel Controls apply a voltage offset to the Control Signal Inputs Extremely long cycles may be achieved by setting Rise and Fall to about 50 and patching a slow clock to HANG It helps to have control over the WIDTH of the gate clock applied to the HANG input so another MATHS or other modules with Gate clock width control such as Pro Modular CLOQ will be very handy Use the Inverted Signal OUT where you require reversed modulation but do not have means for inversion at the CV destination no attenuvertor Feeding the Inverted Signal OUT back into the FUNCTION at any of the CV inputs is highly useful see patch tips Patch Ideas Analog Control Voltages Voltage Controlled Transient Generator Attack Decay Envelope A pulse or gate applied to the Trigger IN starts the transient function which rises from OV to 8V at a rate determined by the Rise parameter then Falls from 8V to OV at a rate determined by the Fall parameter This function is re trigger able during the falling portion Rise and Fall are independently voltage controllable with response as set by the Vari Response panel Control Voltage Controlled Sustained Function Generator A S R Envelope A gate applied to the Signal IN starts the function which rises from OV to the level of the applied Gate at a rate dete
