Alesis Ion analogue synthesizerDeveloped by innovative Alesis engineering and DSP technology, the Alesis ION is a high-resolution analog modeling synthesizer offering breakthrough processing power, real-time control, and great value.Ion Features:
|
The ION features an ergonomic user interface with 3 variably-illuminating control wheels and 31 amply spaced control knobs. The knobs are 360 degree potentiometers with 12-bit resolution, yielding 32 times the resolution of a typical MIDI controller, yet still compatible with the latest sequencers via NRPNs (Non-Registered Parameter Numbers). The result is extraordinary precisionvoid of any undesirable digital artifactsand a very analog sound throughout the entire frequency range.
A 160x160 graphic display provides instant visual feedback as a parameter is edited. The ION keyboard contains 49 velocity-sensitive keys, 4 analog outputs and 2 stereo analog inputs (all balanced and using 24-bit conversion), 4 individual insert effects, a stereo master multi-FX processor, and an internal universal power supply.
Developed by a world-class sound design team, many of whom programmed the flagship Andromeda synthesizer, the IONs 512 user-rewritable presets cover a variety of genres, including many exciting new tonalities, as well as classic synth emulations. New sounds will also be available from the Alesis website, as will a Flash demo of the ION.
