Universal Contour Architect

an Envelope Generator with voltage controlled Delay (Positive/Negative), Attack, Hold , Decay, Sustain (Negative Hold) and Release.

• all stages have CV inputs

• all stages have state gate outputs to trigger other events (e.g. envelopes)
  or to act as a 6-step non-linear, free-running, trigger sequencer.

• Log/Exponential controls for Attack, Decay and Release

• Delay
  0 to 5V delays the start of the envelope
  PULL KNOB: 0 to -5V chops off the beginning of the attack stage (starting the envelope above 0V)

• Hold1, Hold2
  PULL KNOB: 0 to -5V chops off the beginning of the next stage (starting the envelope above 0V)

• D |AHD| mode
  Delay Time : Attack Time : Hold Time (@5V) : Decay Time : Repeat Time (SUS) : Fade Out Amount (REL)

• LOOP mode
  the same structure in a loop (LFO)
  Gate In doubles as Sync input

• SUSTAIN mode
  standard Sustain stage, the knob controls Sustain Level from -5V to 5V or 0-10V

• Loop Input
  CV switch of the loop mode.
  In Sustain Trigger mode, longer gate to Gate In suspends the loop for the duration of the gate and resumes the loop on gate off.

• Trigger Out: outputs a sequence of short pulses for all envelope stages

• Manual Envelope trigger button

• Polarity switch: AC, DC

• Speed Range switch: audio, medium, slow

• 1V/OCT CV input controlling all stages

• all state outputs can output either full gates or just short triggers
