DIY Looping Delay Kit [LD Kit]

Do-It-Yourself Kit for the Looping Delay module.

Crystal-clear clock-synced delay for looping up to 90 seconds, echoes, sound-on-sound, Karplus-Strong synthesis, and more.

March 2024: temporarily out of stock, but available from our dealers.


DIY Kit:

  • Easy assembly: all through-hole components. No SMT or wiring
  • Perfect kit for beginners and experts alike
  • 48kHz, 24-bit low-noise audio: same hi-fidelity as other 4ms modules
  • DSP chips and processor are pre-soldered onto a separate plug-in board


  • Loop or echo time is synchronized to a clock
  • 87 seconds of delay/loop time maximum
  • 48kHz/24-bit sampling rate, loop recorded at 16-bit (24-bit optional)
  • Extremely quiet, low noise and low jitter design
  • Tap tempo button and clock Ping input set the basis for one "beat"
  • Delay/loop time set as a number of musical beats (or fractions of beats) using the Time knob, switch, and CV jack
  • Sample-accurate clock output for perfect synchronization
  • Loop clock output
  • Time switches change range of Time knob from 1/8th notes up to 32 bars
  • Digital feedback, up to 110%
  • Delay Feed control, independent of dry/wet signal mix
  • Infinite Hold mode disables recording input and fixes regeneration at exactly 100%
  • Reverse mode plays memory contents backwards
  • With an infinite loop locked, knobs or CV can "window" around memory, by shifting the loop
  • Trigger inputs for toggling Infinite Hold and Reverse
  • Send and Return for applying effects to feedback with external modules
  • CV jacks to control Time, Level, Feedback and Dry/Wet Mix
  • 16HP Eurorack module
