The Alesis Ion
is an analog modeling synthesizer
. It was presented to the public on the Summer NAMM
of 2002 . Unlike the Alesis Andromeda
, Alesis's analog synthesizer, its sounds are synthesized using DSP
chips to mimic the sound of analog audio circuitry and components.
The Ion has several features that make it stand apart from other analog modeling synthesizers. Most importantly, it features a selection of emulations of classic analog filter models of synthesizers such as the Moog Minimoog
, Oberheim's SEM
, the Roland TB-303
, the ARP 2600
and the Roland Jupiter 8
. Besides these emulations (which carry euphemistic names due to copyright issues), it has a series of filter models that are not commonly found on most synthesizers, such as formant
filters. This vastly increases the sonic range; most virtual analogs have only a single multimode filter (usually featuring low-pass
modes) which was either designed from scratch or "inspired by" an existing "famous" filter model. The fact that two of these filters can be used in a parallel or serial configuration adds to the sound design possibilities.
Besides the selection of filters, it has an extensive modulation matrix. This allows the user to route a source (such as an LFO
) to various targets with an adjustable intensity. The Ion's extensive "Mod Matrix" rivals the routing options of some voltage-controlled modular synthesizers.
