Ritual Electronics - Crypta 1U

Crypta by Ritual Electronics — 1U Delay Based on the PT2399 Chip Originally Found in Karaoke Machines.

Crypta from Ritual Electronics is a 1U delay module built around the PT2399 chip — an analog/digital hybrid originally designed for karaoke machines but now prized for its unique character. While most designs using this chip limit delay times to around 400ms, Crypta extends this to nearly 4 seconds. At shorter settings, you'll get cleaner echoes; as you increase time, the sound degrades into more gritty territory.

Crypta also features a "Poubelle" switch (French for "trash can"). This three-position toggle transforms the signal from clean in the middle position to deliberately broken when flipped up or down - circuit bending built right into the design.

With Feedback cranked high, Crypta becomes its own sound generator, capable of everything from resonant tones to harsh noise. The Time CV input with attenuator allows external control over the delay time, making it possible to deliver chorusing, flanging, and wild pitch-shifting effects when modulated.

Crypta really has its own delay character and is capable of a wider range of sounds than you first might think; it's also a great use of your 1U row!
