The MiniFuse line comes with a solid bundle of software including Ableton Live Lite, Analog Lab Intro, a bundle of four Arturia FX, Native Instruments Guitar Rig 6 LE and three month subscriptions to both Auto-Tune Unlimited and Splice. The extra outputs and inputs are especially handy for routing audio out of your computer, processing it with external effects then running it back into your DAW for final mixing. If you use a decent amount of outboard gear or frequently work with a vocalist this is probably the way to go. But it has line inputs around the back, two additional audio outputs and an additional headphone jack so you and a collaborator can both monitor a track together without filling your recording space with more noise. The MiniFuse 4 hasn't gotten a price tag yet, and wont be shipping until next year. This is handy for recording live audio when even the tiniest of latency is unacceptable. The $149 MiniFuse 2 adds a second input, MIDI in and out ports and has a mix control for balancing between direct monitoring of your input and what's coming out of your PC.
