Overview

Goatkeeper 3 is an all analog signal path, digitally controlled tremolo. It's unique sound is due it's analog VCA (Voltage Controlled Amplifier) and highly customizable waveforms. Six of the eleven waveforms are standard; the other five can be created and saved using the waveform recorder function. Either Goatkeeper's depth knob or the expression/CV input can be used as the source for waveform recording. A four step sequencer multiplies the LFO's rate by either 1,2,3,4,6,8, or 16. A step can also be set to Full amplitude or Minimum Amplitude. The Random setting will select between 1 through 16 or Minimum Amplitude. LFO rate is set by tap tempo (requiring two or more taps), the expression/CV input, or external sync input.

Features

Capable of completely unique sounds as well as standard tremolo

Advanced LFO
- Four step sequencer
- Skip a step by setting it to ">>"
- Set the step to multiply the speed by 2,3,4,6,8,16
- Set the step to minimum or maximum amplitude
- Set the step to Random, selecting between 1 through 16 ro minimum amplitude
- Waveform Recorder function - draw an arbitrary waveform
- Six preset waveforms and five slots for user drawn waveforms

Tap tempo speed control
- Set tempo duration from approximately 250 msec to 6 seconds
- The resulting speed can then be multiplied by up to 16 times using the sequencer knobs

Either the depth knob or expression/CV input is used to "draw" the waveform when in Waveform Record mode

Expression/CV input for control over LFO rate

External sync input - syncs Goatkeeper to an audio click track

100% analog signal path

Relay bypass
