Last issue we looked at the many functions of a typical filter, using the module included with Cherry Audio’s Voltage Modular Nucleus. We showed you each of the onboard filter types (low-pass, high-pass etc) and two slopes. We learnt how the filter’s ability to carve away selected frequencies make subtractive synthesis, well, subtractive and how it affects some of the waveforms produced by a typical analogue oscillator.
This month, we’ll use that sculpting power to create some familiar timbral effects.
A filter is at its best used dynamically - simply setting the cutoff frequency and leaving it alone does not make for an exciting sound! Such a static approach surely has uses - especially when using a filter as a corrective tool - but the best synth sounds are organic, ever-changing, and when combined with other modules, filters are great for imparting motion and life.
