Alesis Fusion Tutorial

ALESIS FUSION ANALOG SYNTHESIS TUTORIAL
Modelled filters
Many of the old, original synthesisers’ filters were known for their ‘sound’ - some quality about
them that made them unique or gave them a certain character. The defining element was
invariably the filter. This was often as a result of component intolerances, inadequacies or flaws
in the design and/or other ‘irregularities’. Using advanced digital sound processing (DSP), it is
possible to ‘model’ or recreate the irregularities present in the analog circuitry of these filters
and thus recreate the character of the original.
Fusion currently includes a filter modelled on the one found in one of the classic semi-modular
synths of the early 70s.
