 While most virtual analog synthesizers are equipped with on-board effects, the Ion lacks two important ones; reverb and a long 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.
