maybe i am missing something here,....
but you DO have a fader for 5/6, and you DO have a fader for 7/8. SO you can mix them. As for panning, they are just pre-panned hard l/r. You dont HAVE to use them as bounce track...UNLESS you want to.
by a "stereo pair" i mean an input source that has two sides. a left, and a right. They MIX on one fader control, because they are a pair. An example of this would be a KEYBORD, that has a L/R output, ( a stereo output, like even a headphone) or a drum module.
Even though there is one fader, it is essentially controlling two channels.
Here is how i set up my MR-8 If it helps.
(Note that i do NOT do the conversion to a stereo file)
I record my stereo drum machine, an Alesis SR-16, into tracks 7/8, left to A, right to B input .
i then record my guitar from my Digi-Tech effects pedal into 5/6, again left to A, right to B. cabinet voiced, sounds great
I record a Bass guitar track, in MONO on channel 4. I usually pan to 11:00, just barely off center
I record a rythm guitar track, in MONO on track 3. I pan it about 3:00, which puts it on the right side of the "sound stage"
I put my harmony/bg vocal on track 2, panned oppisite...9:00 on the left side of the "sound stage", and a little reverb to set it back.
I put my Lead Vocal on track 1, again, near center .
I then mix ALL 8 TRACKS to a STEREO output....in my case the difital SP/DIF
and burn to CD once i get my mix happy and my mastering applied.
But if i wanted to, i could (by using wave manager) take each wave file,
tr01.wav, tr02.wav etc and import them into the computer for further editing.
Would have 8 wave files that way.
Now, what if i want even more tracks. i want to record 4 or 5 singers individually. When you do this in the TAPE world, you loose quality QUICKLY...but in the digital world, it works great
i could record the 2 drum tracks onto 1/2, bass guitar onto 3, and rythm guitar onto 4. and the lead guitar stereo pair onto 5/6.
MIX it carefully, 'cause you cant go back. Then bounce 1 thru 6 to 7/8
erase the unused stuff, and start again.
2 stage mikes on a piano into 1/2,
a mike for a violin,into 3, and a crash symbol into 4.
once again, mix carefully and bounce 1 thru 4 into 5/6. erase 1-4,
start over and record your 4 singers individually
Track 7/8 has 6 tracks, 5/6 has 4, that's 10, + 1thru 4 again, thats 14 track recorded
you can do really neat stuff in the digital world this way
hope this clears up some fuzzy edges for you
