AQA Elektrix Eurorack Dual Delay Module

The Dual VC Delay consists of 2 equal, independent delays A and B, each with it´s own feedback loop.
Each contains a 6dB HP and a 6dB LP filter (not VC), but the internal feedback loop can be opened by patching a cable into the „IN FB“ - jacks to route other signal-processing modules into the feedback-loop. Please note that there is no „Dry-Signal“-path. By designing the module, we thought, it would be mostly used in combination with other modules to achieve some echoes and reverberated ambience, one could put one delay in the feedback-path of another delay for example – there are many different routing configurations, achieving strange modulated reverberated space by combining several Dual VC Delay-modules in various manner.
Due to it´s vast flexibility, the module offers load´s of possibilities for hours-longing sessions of mangling signals, pitch modulation and the generation of phantastic ethereal outer galactic spaces. Used in parallel/stereo-mode, it generates voltage controlled modulated spatial effects with it´s own special character. The sound of the Princeton PT2399 delay chip often reminds for BBD-circuit´s which principle in fact shares similarities with the function of the PT2399 chip. Because the audio -and CV - input´s are normalized in the scheme of A=>B, the module is following your needs for many different patching situations easily. The sonic possibilities of using several module together can be mind blowing, especially when the almost endless possibilities of different feedback-routing are explored.
Delays can be routed in parallel or serial configuration (A => B or A II B)

using normalized feedback in and out jacks, the feedback loops can be opened to insert other stuff

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. The Erica Black series are a range of modules that together make an entire synthesizer.

T-Rex Replicator Eurorack Tape Delay Module


The Replicator Module uses much of the same technology of the ”stompbox” version, but certain parameters and features are optimized for Eurorack/studio use.
CV inputs accept 0-5V control signals, so you can now plug in your favorite oscillator module and control delay time and/or feedback electronically.
Pair it up with a funky, modern wave generator for
a perfect marriage between 70´s ambience and contemporary sound manipulation.
The added filter switch dampens high frequency content in the delay signal for less noise and a darker echo.
The internal power rails has been modified to run from the +/-12V Eurorack standard, so you get all the same sounds and features from the pedal version, but in a more studio/keyboard/synth-friendly format.

Get creative with CV control of true tape echos, process instrument signals/tracks in the studio or use as a table top echo unit for live sound.

All analog echos and signal path
Delay time controlled by a digitally controlled motor
Three echo modes, modulation of the echo and tap tempo
CV inputs for controlling time/feedback – get super spacious, yet ultra cool sounds
Kill-dry switch for parallel processing (mixer)
Housed in a compact Eurorack module (44HP)

Erica Synths Fusion Delay/Flanger Eurorack Effects Module

Erica Synths Fusion Delay/Flanger/Vintage Ensemble module is distinct multifunctional analogue effects module that combines BBD chip based effects with an adjustable tube overdrive in the delay output and feedback path for extra thickness of sound.

For more flexibility, lowpass filtering is fully adjustable from none to extreme. Special feature, not found in eurorack, is Vintage Stereo Ensemble – effect that’s common on vintage synthesizers to create moving and thick spatial sound from a monaural tone generator, be it FM, DCO or any other kind. Such a spatial effect is achieved by mixing dry source with delayed and lowpass filtered out of phase signal.

2hp Freez Eurorack Locked Looper Module

Freez is a voltage controlled locked looper. It captures moments of audio in buffers, where they can be minced and mangled beyond recognition. Once frozen, adjusting size will cause pitch and timbre changes to the locked audio. Adjusting the sample rate control will distort and decimate the incoming audio as well as warp the time domain of the currently locked buffer. From beat repeat to granular audio buffer, Freez will create new sounds and textures out of any input signal.

- Voltage controlled locked looper

- Sample rate up to 96kHz

- Buffer size ranges from microseconds to 3 seconds long

- Beat repeat

- Bit crusher
