"VCA/Contours" is part of the of planet.6modularsystems/:Level^Contour bundle

The VCA/Contours module is a dual amplifier that can be used to level audio and cv signals. It can be used as a traditional VCA or a more complex module to shape your cv signals. The conceptual idea of this module is: the ability to created evolving cv signals - ment for drones or varying cv modulation on frequency and/or filters.

Contours includes offset and a fade-mixer to mix cv 2 in cv 1 and visa-versa. The cv signals can be set to unipolar or bi-polar. While unipolar is more traditional, bi-polar inverts the incoming signal. Next to that it has a function to invert the complete cv signal.

Signal routing: (input signal x gain) + (input signal x ((cv x cv attentuation) x invert) + offset = output signal

The controls and their functions from left to right:

  • Offset knob: sets the amount of offset, it's range is -5 to 5v.
  • Offset leds: the leds show if the out 1 is producing a signal above 0 (top led) or below 0 (bottom led). This helps determining quickly how much offset you want to apply without having to use a scope.
  • Attenuator knobs: The attenuator sets the amount of offset-cv passed through to the offset knob.
  • Offset jack: is the jack that receives the cv-signal for attenuating the offset.
  • Turquoise & Yellow gain knob: These are the gain knobs which multiply the incoming channel.
  • In jacks: Are the jacks for the incoming signal to be amplified.
  • Attenuator knobs located under the gain knobs: The attenuators set the intensity of cv modulation of the gain-jack.
  • Invert led: This led lights up as soon as a gate signal is received and the in-signal is inverted.
  • Invert jack: This jack is used to receive the gate signal for inverting the cv-signal.
  • Gain jack: This jack is the cv signal for attenuation of the gain.
  • Fade knob: sets the amount of cross-mixing from the turquoise-cv to the yellow-cv.
  1. When the knob is completely to the left the turquoise-cv channel is: 50% turquoise and 50% yellow - yellow-cv remains at 100%.
  2. At center cv-turquoise and cv-yellow are both 100% and no cross-mixing occurs.
  3. When the knob is completely to the right the yellow-cv channel is: 50%-yellow and 50% turquoise - turquoise-cv remains at 100%.
  • The leds located next to the fade knob indicate if yellow-cv or turqoise-cv is mixed to the cv-signal. The fade knob can be attenuated to automate fading using the attenuator and jack located under the fade-knob. Setting the fade knob in center and using the attenuator results in cross-mixing. The leds indicated when cross-mixing occurs.
  • Mode switch: This switch determines if the signal received by the gain jack passes the signal through as uni-polar or bi-polar. Bi-polar results in inverting the incoming signal.
  • Out: This is the output jack after the input signal is processed
  • 1/2: This output jack produces a wave-sliced signal of 1 and 2, the top (0-10v) is the turquoise output and the bottom (-10v to 0v) is the yellow output.*
  • 2/1: This output jack produces a wave-sliced signal of 2 and 1, the top (0-10v) is the yellow output and the bottom (-10v to 0v) is the turquoise output.*
