The Alesis Ion is an analog modeling synthesizer
Analog modeling synthesizer
An Analog Modeling Synthesizer is a synthesizer that generates the sounds of traditional analog synthesizers using DSP components and software algorithms to simulate the behaviour of the original electric and electronic circuitry, in order to obtain the sound in a more precise manner from the...

Features

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
Minimoog
The Minimoog is a monophonic analog synthesizer, invented by Bill Hemsath and Robert Moog. It was released in 1970 by R.A. Moog Inc. , and production was stopped in 1981. It was re-designed by Robert Moog in 2002 and released as Minimoog Voyager.The Minimoog was designed in response to the use of...

The Oberheim polyphonic is an analog music synthesizer that was produced from 1974 to 1979 by Oberheim electronics. Tom Oberheim, the founder, knew that musicians needed a way to play chords on the synthesizers that were becoming popular in all styles of music in the 1970s. Except for huge, custom,...

 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

A low-pass filter is an electronic filter that passes low-frequency signals but attenuates signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter. It is sometimes called a high-cut filter, or treble cut filter...

 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
Low frequency oscillation

) to various targets with an adjustable intensity. The Ion's extensive "Mod Matrix" rivals the routing options of some voltage-controlled modular synthesizers.

While most virtual analog synthesizers are equipped with on-board effects, the Ion lacks two important ones; reverb
Reverberation
Reverberation is the persistence of sound in a particular space after the original sound is removed. A reverberation, or reverb, is created when a sound is produced in an enclosed space causing a large number of echoes to build up and then slowly decay as the sound is absorbed by the walls and air...

 and a long delay
Delay (audio effect)
Delay is an audio effect which records an input signal to an audio storage medium, and then plays it back after a period of time. The delayed signal may either be played back multiple times, or played back into the recording again, to create the sound of a repeating, decaying echo.-Early delay...

 (the on-board delay only has 80ms of delay time). These are often used on synthesizers to add some atmosphere to what would otherwise be a "dry" sound.

One feature that also sets it apart from other virtual analog synthesizers, is the high resolution of the endless rotating front panel knobs yielding a more precise real-time tweaking experience. This high resolution eliminates all "stair stepping" or quantization of parameter value changes. These are not encoders, but real endless potentiometers.

Alesis Micron

The little brother of the Ion is the Alesis Micron, which is extremely compact and portable. It came out in 2004 with almost the same synthesis engine and the same metal/plastic housing style as the Ion, but with only 37 keys and fewer knobs and buttons. It boasts reverb, long delay, and a pattern sequencer. Sound patches for the Ion can be used on the Micron and vice versa.

Akai Miniak

In 2009, Alesis's partner Akai released its Akai Miniak, which has the same sound engine as the Micron, but in a differently styled plastic housing, with three modulation wheels instead of the Micron's two sliders plus one wheel, and with a different set of presets. Unlike the Micron, the Miniak standard comes with a gooseneck microphone. Pricing of the Miniak was substantially - typically 50% - higher upon release than the Micron's. In mid-2010 the price was dropped drastically.
