DIY Looping Delay Kit

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.

DIY Kit:

Features

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
