An A/B CV Processor module that allows switching or morphing between two settings (A and B, each between -100% and +100%) for each of six channels, with the setting attenuating the signal from the channel's input (or, if no jack connected, a fixed +5V). The A/B morphing is controlled by an External CV (0V to 5V or -5V to +5V with +5V=B) or Internally, using the same approach as the Multi A/B Selectors, i.e. by a button or via triggers/gates for direct setting of A or B toggling (latched triggers) or a gate signal (normal or inverted) to control the selected set of inputs.

When controlled Internally and like the Multi A/B Selectors, each of the six channels can be set to switched mode or to have smoothing enabled (Cross-Fade) to stop clicks if switching audio or to fade between a set of control voltage inputs to morph between settings; the cross-fade speed (for the whole module) defaults to 25ms but can be set to between 0ms and 12secs; and the module also provides a Gate Out (off=A, on=B) so that multiple modules can be cascaded if you need more than six channels switched at the same time.

This module is designed to be used to morph or switch between two different patches or settings of modules by having a set of different DC outputs (to control e.g. Filter Frequency/Q settings) and/or different levels of CV controls (such as LFOs, etc.) in the A and B modes. The morphing of the patch can then be controlled manually by a mod wheel, a slow LFO or even a long/delayed envelope triggered by the keyboard.

Also sold as part of the Multi A/B Selector Bundle, Andrew Macaulay's Switches and Mixers and included in Andrew Macaulay's Ultimate Bundle.

Andrew Macaulay's modules are a suite of Control and Utility focused modules for Voltage Modular around gates/trigger handling, envelopes, ratcheting/sequencing and mixing/switching. Andrew is a musician and retired IT pro who started developing modules for Voltage Modular to add useful tools for use in his own compositions before deciding to share them through the store.
