Sounds like you either need an XT or X3 Live. The main difference between these is the dual tone. If you use the PodFarm software you get dual tones - but if you have an XT you'll only get them if you're on your computer. To get the dual tones live you will need the X3.

The only real difference to owning the the 'bean' version of the Pods with separate floor control is the cost. If you're happy having separate devices at a higher cost then go for what you prefer.

Monkey is the program that checks all your software (XT/X3 firmware, drivers etc) are all up to date.

PodFarm is the latest way to edit patches but uses the computer's CPU rather than the XT/X3. The XT/X3 acts as a dongle for the PodFarm software.

GearBox directly edits the XT/X3 if you prefer to do that (as does the oft preferred but old Line6 Edit).

Gearbox is what you want!  IMO...

Input 1 (Instrument) – Connect your guitar or bass here using a standard 1/4-inch TS instrument cable. POD X3 itself contains the processing power that turns your naked input signal into that roaring guitar Tone, which is then fed to the “Direct/Studio Mix” and out the Analog Left & Right Outputs and S/PDIF digital output. This signal is also fed to POD X3’s Record Sends digitally to your computer across the USB 2.0 connection. When you are connected via USB to your computer, you can also launch GearBox and use it to alternatively load Tones stored on your hard disc, edit them on your screen, and make adjustments for output and Record Send levels. POD X3 is, of course, also capable of applying two Tones on your Input 1. Just dial up one of the tone presets in the “Blends” folder of POD X3 and you’ll have two complete Tones applied to your Input 1 signal! Or, go the POD X3’s Inputs screen to choose what you want Tone 1 and Tone 2 applied to.
Input 2 (Mic) & Trim knob – Connect a microphone here using a standard XLR cable. You can use the little “Trim” knob to adjust the mic signal coming into POD X3, much like you would on a mixer console. Just like with Input 1, POD X3 itself applies preamp and effects models to your mic input, which is then fed out the Analog Left & Right Outputs and S/PDIF digital output. This signal is also fed out the X3’s Record Sends digitally to your computer across the USB 2.0 connection. When you are connected via USB to your computer, you can also launch GearBox and use it to alternatively load Tones stored on your hard disc, edit them on your screen, and make adjustments for output and Record Send levels. POD X3 is, of course, also capable of applying a Dual-Tone, such as independently slathering a guitar Tone on Input 1, and a mic preamp and effects on Input 2 simultaneously! Just go to the “Pairs” folder of your POD X3 to call up some of these pre-baked guitar/mic Dual-Tones! Or, go the POD X3’s Inputs screen to choose what you want Tone 1 and Tone 2 applied to.
