There are two soundcards involved in your setup: the one inside your computer, and the UX1. Depending on how your computer's 'Sound' control panel is configured, and on what applications are running, your computer may be using either card at a given time. If your computer's soundcard is being used then the computer-generated sound will be directed to your computer outputs. If the UX1 is being used then the computer-generated sound will be directed to the UX1 outputs.
When Pod Farm is running it will always use your UX1 (or other connected ASIO device, if you have the hardware independent version of Pod Farm 2.5) regardless of which soundcard is your default device. When Pod Farm is not running, your computer may use its default soundcard, which could be your internal soundcard. You can configure your computer to always use the UX1 when it is connected by making the UX1 your default soundcard (use the Sound control panel item). By making the UX1 your default sound card you will always get your computer's sound coming from the UX1 outputs as long as the UX1 is connected.
Hope this helps.
The issue and questions don't really concern the computer's on-board soundcard, and aren't so much about computer generated sounds as with the guitar/instrument input. It (the UX1) is already configured as the default soundcard; that part I am familiar with. What I am not clear on is with this setup,
a) Does/should there always be guitar/inst. output from the UX1 outputs even when Pod Farm, nor any other modeling type software is running?
b) If it does then how does/is it supposed to function when Pod Farm IS running, i.e. what is output, dry signal, wet signal, both? Does software then take precedence over the direct tone feature and override it with the software's output? Is it then down to confuguration within Pod Farm, i.e sending either the dry or wet signal as selected?
In a nutshell, I just don't understand what "Direct Tone" is, or how it does or is supposed to function.
I'm not entirely sure about your question a). It seems that you are hearing this dry output even when Pod Farm is not running. I haven't tested this because I don't have a UX2, but I would assume it is normal behaviour. Similarly I can't test b), but certainly the wet signal is output, and in most cases will overpower the dry signal so that, even if it is present, it will be negligible.
My understanding is that Tone Direct monitoring applies only in a recording situation, when Pod Farm is being used as a plugin. You mau already have seen this description from the UX2 product description on the website:
Using exclusive Line 6 ToneDirect monitoring is a tremendous advantage of recording with POD Studio. ToneDirect monitoring allows you to:
record and monitor a fully processed tone free of audible latency.
monitor a processed tone while recording a dry signal which means you're free to audition tones until you're ready to mix.
Historically, traditional interfaces have forced guitarists to choose between monitoring a processed tone with a significant amount of latency and monitoring a dry signal. Both choices are unacceptable and leave recording guitarists irritated and uninspired.
My interpretation of the above is that Pod Farm sends the processed (wet) signal directly to the UX2 outputs as soon as it is available - before/as it processes it within the DAW, thereby minimizing latency because you don't have to wait for the DAW to process/record and echo back the recorded signal. It seems that, even though operating as a plugin, Pod Farm accesses the usb connection directly as if it were operating standalone. So you hear your processed signal without delay while it is being recorded, and your DAW doesn't need to echo it back. This applies even if/when you are recording the dry signal.
Sorry I'm not more clear on what happens with the dry signal when Pod Farm is not running, or when running standalone - but in those situations I believe the term Tone Direct does not apply.
Yeah, I'm starting to think it's just the PC recognizing the USB input as an audio device and routing to the UX1 that way as it's set as the default souncard. That got me to wondering how it all works when I do run Pod Farm or similar and also wondering about just how this Tone Direct is supposed to work and what it really means.
L6 offers suprising little documentation on the hardware itself, everythign is Pod Farm documentation so I couldn;t find much to better explain it. I do recall seeing the above somewhere before when I was shopping for an interface but now that I have the UX1 it just trying to understand it better.
Thanks for your help!
