This video shows the uses and operation of the SPECTRA MIRROR (23B) module by Circuit Shaman. This module is a Resonant multi-mode sampling gate, meaning that it can be used in many ways to attenuate an audio signal using downsampling. It is also capable of many sampling effects that are not possible with typical downsampling effects, such as the ability to downsample only part of the input signal and "high-pass sampling" mode, which attenuates signals below the sampling frequency like a high-pass filter.

This module is available as an assembled module, as a DIY kit and as a PCB/ panel. The PCB is also supported for non-eurorack formats.
