  • Page 3: Limited Warranty

    Make Noise to be the fault of the user are not covered by this warranty, and normal service rates will apply. During the warranty period, any defective products will be repaired or replaced, at the option of Make Noise, on a return-to-Make Noise basis with the customer paying the transit cost to Make Noise.

    Eurorack style bus board, minding the polarity so that the RED stripe on the cable is oriented to the NEGATIVE 12 Volt line on both the module and the bus board. On the Make Noise 6U or 3U Busboard, the negative 12 Volt line is indicated by the white stripe.

    Even small voltages are readable on these LEDs. 3. As Make Noise now o ers a Multiple the Signal Output Multiple (from the original MATHS) has been changed to a Unity Signal Output. It allows for creating two variations of output, one at unity and the other as processed through the Attenuverter.

  • Page 6: Channel 1 Panel Controls

    14 15 MATHS Channel 1 1. Signal Input: Direct Coupled input to circuit. Use for Lag, Portamento, ASR (Attack Sustain Release type envelopes). Also input to Sum/OR Bus. Range +/-10V 2. Trigger Input: Gate or Pulse applied to this input triggers the circuit regardless of activity at the Signal Input. The result being a 0V to 10V function, aka Envelope, whose characteristics are de ned by the Rise, Fall, and Vari-Response parameters.
  • Page 7 9. Fall CV Input: Linear control signal input for Fall parameter. Positive control signals increase Fall time, Negative control signals decrease Fall Time with respect to the Fall panel control. Range +/-8V 10. Cycle Input: On Gate HIGH, Cycles on. On Gate LOW, MATHS does not Cycle (unless the Cycle button is engaged). Requires minimum +2.5V for HIGH.

  • Page 8: Channel 4 Panel Controls

    MATHS Channel 4 1. Signal Input: Direct Coupled input to circuit. Use for Lag, Portamento, ASR (Attack Sustain Release type envelopes). Also input to SUM/OR Bus. Range +/-10V 2. Trigger Input: Gate or Pulse applied to this input triggers the circuit regardless of activity at the Signal Input. The result being a 0V to 10V function, aka Envelope, whose characteristics are de ned by the Rise, Fall, and Vari-Response parameters.

Positive control signals increase Fall time, Negative control signals decrease Fall Time with respect to the Fall panel control. Range +/-8V 10. Cycle Input: On Gate High, circuit Cycles. On Gate Low, MATHS does not Cycle (unless the Cycle button is engaged). Requires minimum +2.5V for High 11.

    SUM and OR Bus 1. Direct Coupled Channel 2 Signal Input to Attenuverter and Sum/OR Bus. Normalized to a +10V reference for generation of voltage o sets. Input Range +/-10Vpp. 2. Direct Coupled Channel 3 Signal Input to Attenuverter and Sum/OR Bus. Normalized to a +5V reference for generation of voltage o sets.
  • Page 11 SUM and OR Bus (cont’d) 7. CH. 1 Variable Output: The applied signal as processed by CH. 1 controls. Normalized to the SUM and OR busses. Inserting a patch cable removes the signal from the SUM and OR busses. Output Range +/-10V 8.

    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.

    Signal Input and Trigger Input. The range of times is larger than the typical Envelope or LFO. MATHS creates functions as slow as 25 minutes (Rise and Fall full CW and external control signals added to go into "slow-ver-drive") and as fast as 1khz (audio rate).

  • Page 14: Signal Outputs

    Signal Outputs There are many di erent 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 labeled 1, 2, 3 and 4 and are associated with the four Attenuverter controls in the center of the module. These outputs are all determined by the settings of their associated controls, esp.

  • Page 15: Tips & Tricks

    -Use the INV SUM Output where you require reversed modulation but do not have means for inversion at the CV destination (Mix CV Input on ECHOPHON, for example). -Feeding an inverted signal from MATHS back into the MATHS at any of the CV inputs is highly useful for creating responses that are not covered by the Vari-Response control alone.

  • Page 20 Patch Ideas: Analog Signal Processing, Voltage MATHS! Envelope Follower Apply signal to be followed to Signal Input CH. 1 or 4. Set Rise to 12:00. Set and or modulate Fall Time to achieve di erent responses. Take output from associated Channel Signal Output for positive and negative Peak Detection. Take output from OR buss Output to achieve more typical Positive Envelope Follower function.
