Modbap Modular Per4mer

Quad arcade-button performance FX for beatmakers and DJs

14 HP Eurorack module

Per4mer is a quad performance FX eurorack module featuring delay, reverb, glitch, and tape stop effects triggered by four arcade buttons, designed for live beatmaker and DJ-style improvisation. It also includes compression and color processing with eight tonal presets, CV and gate control over all effects, and tap tempo sync. The module draws inspiration from hip-hop and boom-bap performance techniques, bringing spontaneous, rhythmic FX triggering to the modular world.

Features

  • 4 arcade buttons rated at 10 million presses for triggering delay, reverb, glitch, and tape stop
  • Momentary and latched triggering of performance effects
  • 4 rotary FX knobs with context-sensitive parameter assignment based on last selected effect
  • Delay effect with wet/dry, time, feedback, and filter cutoff parameters
  • Reverb effect with wet/dry, time, decay, and pre-delay parameters
  • Glitch effect with wet/dry, size, pitch (+/-2 octaves), and reverse parameters
  • Tape stop effect with wet/dry, time, slope/curve, and low pass filter parameters
  • Per-effect envelope control via Shift+FX1 (attack 5ms-5sec) and Shift+FX2 (release 5ms-5sec)
  • Color processing effect with 8 fixed presets: Classic, LoFi, Saturation, Wax 1, Wax 2, HP Fixed, LP Fixed, White Noise
  • Adjustable dry/wet mix for color effect via Color + FX1
  • Compressor with threshold, ratio (2:1, 3:1, 4:1, 8:1, 12:1), attack, release, and make-up gain
  • Sidechain input with three source options: audio input, sidechain CV input, clock input

Controls & Jacks (26)

  • GLITCH— Large performance knob controlling glitch effect intensity and pattern. Illuminated ring shows current value.
  • Gate 1 (Delay)— Gate input for the Delay effect. A high gate engages Delay; a low gate releases it.
  • Gate 4 (Tape Stop)— Gate input for the Tape Stop effect. A high gate engages Tape Stop; a low gate releases it.
  • Gate 3 (Glitch)— Gate input for the Glitch effect. A high gate engages Glitch; a low gate releases it.
  • CV4— CV input for FX4 (Tape Stop) send level. Voltage controls tape stop mix.
  • OUTPUT R— Right stereo processed audio output.
  • INPUT R— Right stereo audio input. Accepts Eurorack or line level signals.
  • Gate 2 (Reverb)— Gate input for the Reverb effect. A high gate engages Reverb; a low gate releases it.
  • CV2— CV input for FX2 (Reverb) send level. Voltage controls reverb mix.
  • CV1— CV input for FX1 (Delay) send level. Voltage controls delay mix.
  • CV3— CV input for FX3 (Glitch) send level. Voltage controls glitch mix.
  • OUTPUT L— Left stereo processed audio output.
  • SIDE CHAIN— Side chain input for the compressor. External audio signal fed here controls the compression envelope applied to the main signal.
  • INPUT L— Left stereo audio input. Accepts Eurorack or line level signals.
  • TAPE STOP— Large performance knob controlling tape stop effect speed and curve. Illuminated ring shows current value.
  • DELAY— Large performance knob controlling delay effect depth and feedback. Illuminated ring shows current value.
  • CLOCK— External clock input for syncing delay time and other tempo-based effects to external sources.
  • FX4— Controls the FX send level for channel 4 (Tape Stop). Sets the wet/dry mix for the tape stop effect.
  • REVERB— Large performance knob controlling reverb effect size and decay. Illuminated ring shows current value.
  • FX1— Controls the FX send level for channel 1 (Delay). Sets the wet/dry mix for the delay effect.
  • FX2— Controls the FX send level for channel 2 (Reverb). Sets the wet/dry mix for the reverb effect.
  • FX3— Controls the FX send level for channel 3 (Glitch). Sets the wet/dry mix for the glitch effect.
  • SHIFT— Shift button for accessing secondary functions. Hold while adjusting other controls for alternate parameters.
  • COLOR— Controls the tonal character and color of the effects. Adjusts filter/EQ applied to effect signals.
  • COMP— Controls the compression amount applied to the output. Higher values increase compression ratio and makeup gain.
  • TAP— Tap tempo button for setting delay time. Tap repeatedly to set BPM. LED indicates tempo.
