[LAU] Mono tracks to mono or stereo bus ? And sampling rate

[jonetsu at teksavvy.com]

Hello all,

When having multiple mono guitar tracks in Ardour and wanting to
regroup them in a single bus, would that bus be preferably mono or
stereo ?  How is this in relation to eventually placing the guitar bus
in a stereo field ?

Also, is it possible in Ardour to raise the sampling rate of single
tracks ?  I just followed the part of the Brian Bollman music production
(free) course about sampling rates.  The higher the rate the more
fidelity to the original signal and also the more material to work with
when bringing it down to CD or ogg/mp3 level.  I would like to try with
the guitar and bass tracks as I don't care so much about synths for
now.  Is it possible to tell Ardour to work with a higher sampling rate
for a track ?  I don't seem to have found the option.

Cheers.
