  • Page 3: Introduction

    StarLab - time-warped reverberator Introduction StarLab expands the sound of your Eurorack rig with lush reverbs as well as chorus, flanging, and modulated delays. StarLab is also a full- featured Karplus-Strong string synthesis voice module that allows freely alternating bowing and plucking as well as dynamic string damping.

Karplus-Strong Mode Karplus-Strong mode provides a monophonic, delay-based string synthesizer which can be plucked or bowed like a stringed instrument. When in Karplus-Strong mode, the DELAY/KARPLUS controls have a different functionality set than in delay mode. To enter Karplus-Strong mode: Hold the ECHO ON button and turn the DELAY/TUNE knob clockwise until the TAP/TRIG button turns RED.
  • Page 16 StarLab - time-warped reverberator DELAY/KARPLUS Controls and Connections (cont.) DELAY/TUNE: Sets string tuning over a continuous 4 octave range. When SIZE/PITCH CV is detected, it sets fine tuning of 12 semitones. Karplus-Strong Pitch Tracking Adjustment: Adjusts the V/oct tracking to compensate for calibration errors in external control module voltages.

    StarLab - time-warped reverberator HARMONICS Controls and Connections StarLab’s HARMONICS section includes pitch shifting shimmer and harmonic accentuating glimmer effects. SHIMMER: Adds pitch shifting to the reverberated signal. Effect is OFF when the SHIMMER knob is fully counterclockwise. SHIMMER CV: Sets shimmer level. Knob position acts as an offset. •...
  • Page 18 StarLab - time-warped reverberator HARMONICS Controls and Connections (cont.) GLIMMER: Dynamically enhances aspects of the input signal’s harmonic spectrum. Effect is OFF when GLIMMER knob is fully counterclockwise. HIGH BAND: Selects the harmonics to be enhanced by the glimmer effect. When engaged (HIGH BAND LED GREEN), the high band harmonics are enhanced.

  • Page 19: Filter Controls And Connections

    StarLab - time-warped reverberator FILTER Controls and Connections StarLab’s filter section targets the signals going into the reverb tank applying filtering to the high and low frequency content of the reverb. Includes a variable resonance (Q) low pass filter. LOW DAMP: Removes low end content both at the output and in the regenerating core portion of the reverb as the...
  • Page 20 StarLab - time-warped reverberator FILTER Controls and Connections (cont.) LOW PASS: Changes the HIGH DAMP function to a 24dB/ octave low pass filter applied at the output of the reverb. LOW PASS Resonance: Secondary function for the HIGH DAMP knob to adjust the resonance (Q) of the low pass filter. To adjust the LOW PASS Resonance: •...

  • Page 21: Lfo Controls And Connections

    StarLab - time-warped reverberator LFO Controls and Connections StarLab’s LFO section provides modulation which can be assigned to one of three different targets. Targeting the delay modulates the delay time, allowing for chorus, flange and other delay effects. Targeting the pitch modulates the SIZE/PITCH control position.
  • Page 22 StarLab - time-warped reverberator LFO Controls and Connections (cont.) SPEED: Controls the period of the LFO waveform from 15 seconds (0.067Hz) to 1/15th of a second (15Hz). When envelope (env) is the selected waveform, SPEED controls the decay rate of the envelope. When LFO CLK IN CV is detected, SPEED knob acts as a clock divider/multiplier.
  • Page 23 StarLab - time-warped reverberator LFO Controls and Connections (cont.) SHAPE: Selects from six different waveshapes for the LFO, including triangle, square, ramp, saw, random, and envelope which responds to input dynamics with the input sensitivity set by the DEPTH knob. DEPTH: With the exception of the env shape, adjusts the amount of modulation.
