Multitracking done right

[Grml]

Hi all,
I'm not really sure if I understood correctly how to setup up multitracking with Hydra (and the others). Genre is Heavy-/Power Metal. So a lot of Power Chords, Palm Mutes and some solos.

I'm using REAPER.

Anyway...
I have one Midi track with Kontakt on it. Loaded Hydra NKI two times and created two mono outputs sending to two different tracks in REAPER. Those are panned at 95% and 70% to the left.
The guitars in Hydra instance 1 are set to use 1 & 2, while Hydra instance 2 uses 3 & 4. Anti-Repetition is at 50% for both instances.

The virtual amp is from Amplitube 5, same model on both REAPER tracks.

See the screenshot.

While it basically doesn't sound really bad I still hear some kind of phasing problems. Especially on sustain power chords and single notes. Palm mutes are a bit better. But no matter if I activate the phase button for one track in REAPER or not, it doesn't make a real difference.

Can anybody tell me if there is any setting that I need to double-check? Or, with the information from above and the screenshot, what I might be understanding wrong when it comes to multi-tracking?

(And, of course I'm doing exactly the same for the guitars to the right. Another Midi file (with different velocity(!), another Kontakt instance with two NKIs, but routed the same approach described above. Of course, I'm not "re-using" something from the other tracks).

Thanks to anyone who might help me here

You didn't need to create additional outputs (nor make them mono). Shreddage 3 engine already sets up the panning for the additional multitrack enabled "guitars". You should just use a normal stereo output, choose guitar 1 for your first NKI and guitar 2 for your second NKI (for starters). See how that goes?

Thanks for your answer!
But that way I can't use different amps (if I want to) in Reaper. If I understood you correctly.

Anyway, I'll try that the next weekend of course. If it sounds better, it is better

Of course you can use different ampsims. Use Reaper's pin matrix to route things to just the left or just the right channel of the ampsim. Or in something like Guitar Rig, you can run a stereo signal into a single instance, and then use stereo splitter to separately process L and R. Most likely Amplitube can do the same.

Oh, never thought it that way! Thanks! Waiting for the weekend to have time testing that

Ok, tested it, probably with a sligthly different approach (at least to what I understood). But keeping the stereo track in Kontakt and not route to two single tracks here did the trick. Just extended it that way, that I'm actually using 4 guitars per side now and using more capabilities within Kontakt before breaking out into Reaper.

Thanks for your help!
