CV Contour

CV essence from audio

• Amplitude follower
• Clocked S&H, LP
• Experimental frequency follower

CV Contour is a mono channel Audio to CV converter with four separate, simultaneous functions for dynamic modulation within the Reason Rack.

Details

Amplitude follower

• Interpolate between ENV and RMS detection method
• Attack and Release knobs for the ENV method
• Release knob for the RMS method
• Pre and Post gains
• Interpolate between hard and soft clipping
• Normal and inverted CV outs in the back panel

S&H

• Clocked sample and hold
  • It takes a sample value from the incoming audio
• Sample rate between 0.25-64Hz
• Smoothing.
• Gain control for amplifying quiet signals.
• Clock resets when the sequencer starts.

LP

• Lowpass filtered audio signal converted to a CV signal
• Cutoff frequency between 10-100Hz
• Gain control for amplifying quiet signals

ZCR

• Zero cross rate detector
  • a quasi frequency follower
• Reaction time
• Noise floor knob for excluding noise from the detection
• The CV output is normalized to CV Note values
