A New Beginning
The Analogue Replicator was redesigned from scratch to be the finest analogue delay available with a sound and feature set focused around the modular synthesizer.
Pittsburgh's original analogue Delay module grew out of the circuitry of a guitar pedal. The new Analogue Replicator module does not share the same stompbox lineage. Michael Johnsen, Pittsburgh Modular's analogue engineer, created a modern BBD core fed by a unique clock source and proprietary signal processing circuits. The result is a flexible, more musical, eurorack delay module.
How It Works
At the heart of the Analogue Replicator is a pair of 4,096 stage BBD chips. The name BBD stands for [B]ucket [B]rigade [D]evice in reference to a line of people passing buckets of water to quickly extinguish a fire. Each stage of a BBD chip contains a single capacitor. Pairing two chips together creates a chain of 8,192 capacitors. Like the water buckets, an audio signal is passed from capacitor to capacitor within the BBD chips once every clock step. A slower clock produces a longer delay and a faster clock produces a shorter delay.
The controls of the Analogue Replicator can be used to produce a wide range of delay effects. The STAGES switch flips between 4,096 and 8,192 BBD stages. 4,096 uses a single BBD chip and 8,192 uses two. Using both BBD chips doubles the available delay time, perfect for echos and longer delays. Using a single BBD is useful for reverb and chorus effects. The SHORT/LONG switch drastically adjusts the delay range. Using a single BBD, the SHORT range varies between 10ms and 175ms and the long range varies between 10ms and 1300ms. The SHORT mode produces bright, clean analogue repeats. LONG mode is dark and grimy. Mud and clock noise (whine) begin to leak in and eventually take over as the Analogue Replicator reaches the longest available delay time.
Chorus and Reverb
The design of the Analogue Replicator allows it to mimic Chrous and Reverb effects. Setting the switches to 4,096 and SHORT, adjusting the TIME control to create shorter delays, and adding a small to medium amount of FEEDBACK, the Analogue Replicator generates an analogue reverb effect. Add modulation using the TIME CV IN to take advantage of a range of chorus like effects.
