WMD Digital VCA 1/2: De-clicking Attacks (LMS Eurorack Expansion Project)

Published on Jul 27, 2017 Learning Modular

"This first of two movies on the WMD Digital VCA looks at how it can delay an input control voltage such as an envelope until the incoming audio has reached a zero crossing of its waveform. Changing amplitude while the waveform is at zero means there will be no spurious clicks from sudden attacks, while suddenly opening a VCA while a waveform is somewhere else in its cycle can result in an abrupt change and therefore a click.

WMD Digital VCA 2/2: Sample & Hold Application (LMS Eurorack Expansion Project)

Published on Jul 27, 2017

"This second of two movies on the WMD Digital VCA explores using it as an intelligent sample and hold where changes in its amplitude only occur when a gate signal goes high or low. This “quantizes” changes so they only occur at the start of a note (or optionally, at its end)."
