iVamp is an editor for the Behringer V-AMP guitar and bass guitar effects units. All controls operate in real-time so it doesn't matter if you make a control change on the V-AMP itself or within the software. You see and more importantly "hear" the changes immediately.
While live control is versatile for tweaking those tones in your V-AMP, the software would not be complete without a Tone Library function. Installing a tone in your V-AMP is as simple as dragging a tone from the Library and dropping it on the Preset location you want it to be stored in.
