The vaemi-shift-register Eurorack module is a versatile and powerful tool for any electronic musician. This module functions as both a sequencer and an oscillator, providing a range of possibilities for sound design and performance.
As a dual 4-bit Shift Register module, the vaemi-shift-register stores and shifts data in accordance with a clock signal reference. When used as a sequencer, it can be thought of as a 4-step sequencer that outputs a 5V gate signal. The first output gives the same pattern entered in the data signal but synced with the clock, while the subsequent outputs give delayed versions of the pattern. This means that it is possible to create loops and manipulate the phase of recorded patterns by redirecting outputs to the data input and starting the Shift Register at different times. In addition, the module has a reset input for clearing the memory of data.
The module's versatility extends beyond its sequencer capabilities. When used in the audio rate range, it functions as an oscillator with clock signals that are audible to humans. By patching with square waves in Logic, different phase degrees of the data (square wave) you entered can be achieved. The module also has a CV input and gate input, which provide further opportunities for sound design.
The vaemi-shift-register module is a DIY or assembled kit available from en.vaemi.net. Its multi-channel capabilities and extensive range of functions make it an excellent addition to any modular synth setup, particularly for those interested in exploring unconventional sequencing and sound design possibilities.

For a novice-level usage example for the vaemi-shift-register Eurorack module, you can start by connecting the jack on the module labeled "data" to a keyboard or sequencer. Then, connect one of the outputs to a VCO module and another output to a different VCO module. Set the clock signal to a rate that is audible to the human ear. As you press the keys on the keyboard or activate the sequencer, you will hear two separate pitches playing simultaneously. As the clock signal progresses, the pitches will shift and change in a rhythmic manner due to the shifting pattern generated by the module. You can experiment with different clock rates and data inputs to create unique melodies and rhythms.
An intermediate-level usage example for the vaemi-shift-register Eurorack module as a sequencer is to program a drum beat pattern using the data input and clock signal inputs. Connect the first output to a drum module and listen to the 4-step sequencer pattern being played. Then, redirect the fourth output to the data input and start the clock again to create a loop of the pattern. Use the second channel of the Shift Register to extend the pattern even further by connecting the fourth output of the first channel to the data input of the second channel. Experiment with different clock speeds and phase settings to create a unique and dynamic drum beat. As an oscillator, use the clock signal input to generate pitched square wave tones and modulate the waveform using the data input and clock speed.
One of the most creative ways to use the vaemi-shift-register module is by using it as a dual oscillator. By patching clock signals into both data inputs, you can generate two distinct oscillators that are in sync with each other. The output signals can be further processed by using other modules like filters, envelopes, and LFOs to create complex and evolving sounds. This technique opens up a world of creative sound design possibilities, especially when combined with other Eurorack modules. Additionally, the two oscillators can be controlled independently by using different clock speeds or by modulating the clock signals with CV. This allows for even more experimentation and exploration of the module's versatility.
