playing a backing track and recording ONLY the guitar
First of all, I just discovered Ardour by accident (in a Youtube comment I think) after messing around for too long with Audacity (which is a great program itself though)
BTW I noticed that chromium notified me that your SSL certificate has expired. I also noticed that the forum registration process just sent me back to the ardour main page (just saying in case a dev is reading this)
Here's my question, first of all my setup:
Linux mint 12 with gnome 3
Ibanez S-Series guitar
cheap sound card
Vox Amplug Metal
some planet waves adapter thing
The vox amplug is connected to the guitar using a regular guitar cable and some planet waves thingy used as an extension (because the Vox amplug will not fit directly into my Ibanez guitar, because the input plug of this guitar is sinked into the guitar body, and the plug of the Vox amplug is too short!)
Then there's another cable which goes from the green output plug on the front of my PC, back to the Vox Amplug (to feed the backing track into my headphones)
The output of the Vox amplug goes into a 2-way switch cable, with one line going into the red Mic port of my soundcard on the back of my PC, and the other line going straight into the headphones so I can hear the backing track coming from the computer and hear my playing at the same time. All in all it's a weird setup but it works.
Here's my problem:
1. I want to listen to a backing track in Banshee (some ogg files) on my headphones (solved)
2. I want to be able to hear my guitar playing on the same headphones along the backing track (solved)
3. I want to mix my playing over the backing track, so I can send/upload the full overdubbed song for demo purposes (solved, this is simple with Audacity)
4. I occasionally want to record ONLY the guitar playing, to analyse the quality of my playing style without having the original backing track running.
Using audacity, I was able to play back the backing track while playing guitar at the same time, without any latency etc. That works great. Also recording works great, using the Overdub option of Audacity, it'll simply record whatever is playing on the computer. However, I cannot record ONLY the guitar - Audacity will always mix the backing track into my guitar track. For demo purposes it is great, but I really want to analyse my playing.
My question is, do I need to purchase a new sound card and/or a mixer/interface, or can I solve this in software / with Ardour? I also would like to know if this setup is too weird, for example I still get a lot of noise recording with Audacity, I'm not sure if this has to do with a cheap sound card and/or Audacity and/or too much funny cables.
