Another Amateur (Advice on a configuration)

[Mike Holstein]

if you have the hardware, and easy way to do this on the software side would
be to have a separate machine, some cheap laptop would do the job, and some
kind of mixer... you could route the track into the mixer from whereever,
and a microphone, and pipe that into the machines sound card that is running
BUTT... that would combine the sources and doesnt depend on JACK at all...
you could do this with a CD or mp3 player too with a mixer going into one
computer (if you prefer the one computer rig)... even in JACK, its going to
be challenging if your using an onboard sound card... you might think about
splitting the channels left and right and thinking about it more like a 2
track audio device... put the music on one input (mono) and the mic on the
other, and mix those in something with JACK and output to whatever... now
that i think about it, IDJC would be nice actually because it blends the
music and a mic input.. why was that not working for you? the mic latency
didnt match the track?... i have only noticed the mic input in IDJC and
didnt really try using it..
