Spec-wise yes. Sonically, only you can answer that, but the majority would agree the Helix tones are far superior.

It does not show up as a model pack in edit. But you should have new models. Look to see if you have access to amp models that come with the Metal pack. Also if you power cycle the POD you should see it as an installed pack on the splash screen.

Do you have the phantom power turned on?

Did you update the drivers for the UX?

Then you likely had an option selected that has Windows listen to the device.

The UX typically should not go thru your pc speakers. You nee to connect headphone or powered speakers directly to the UX.

No sound form what speakers?

Can you post a screenshot of PF where the knobs are?

Check the level in your DAW of the dry track that you're feeding back to the POD Go.

I don't recall off hand if the POD X3 has a limiter. But a compressor is typically more dynamic than a limiter. Also a compressor with a very high ration may behave like a limiter depending on the model. The POD X3 should have a hardware enabled PF license which gives you all the model backs available and I think the plug-in license.

What are you trying to accomplish? The UX2 can act as a MIDI thru device via USB to send commands to PF. From the manual: MIDI Controller Hardware The POD Farm 2 Plug-In and standalone application both support the use of external MIDI controller devices to remotely access most parameters. You can use any MIDI controller device that is capable of transmitting MIDI CC, Note-On, Pitch Bend and/or Bank & Program Change messages to access POD Farm 2 functions. If you have a Line 6 UX2, UX8 or KB37, then you can utilize the MIDI controller features of these devices with POD Farm 2, as described in the device sections that follow. Link to manual: PF2 Manual

Go to the downloads page and use the dropdowns.

Yes that is the cable. You're KB is stereo so just duplicated one mono channel you are missing half the sound. Do you have Line outs on the KB or just the Headphone out?

Actually the UX2 has 2 Line Ins. Create a dual tone blank patch and select Line1 for A and Line 2 for B and pan hard L & R. You will need the TRS to 2 X mono cable that fflbrgst mentioned.

You do not need the disc. You can download everything from the site.
