Audio Out of Synch?

Hi, I’m completely new to the charting scene, but I’ve been messing around with Feedback and Reaper the past few days just to kind of get a feel for it. I started working on Vince Gill’s “One More Last Chance” since it had a really simple bass/drum line just to get some practice in. I used the Tempo Map and the Metronome in Feedback and finally got the metronome to stay extremely close to the beat all the way through the song.
I went ahead and charter a rough draft of the guitar the other day and it all looked like it lined up perfectly when I played it back, even at 1/2 speed. I imported each track (guitar, bass, drums, music track) all into Reaper at the same exact position, and even going back and watching the RBN preview plugin, everything looks completely in synch. However, when I send it all through Magma C3 and load it up on the 360, the notes are about a quarter second too fast. I messed around with the audio track, adjusting it’s position a little at a time, and finally got it halfway synched up, but it’s still not perfect, and it’s extremely tedious. I’m just trying to understand why everything lines up perfect on the computer end of it, but once its consolidated and imported into Rock Band, the audio is out of synch.
There’s a ton of songs I’d love to chart, and this has kind of held me up for the time being, haha. Just wondering if you guys could point me in the right direction on this? Maybe some kind of trick you all use to get it perfectly synched up all around?

[Note]
Are your audio files placed something like this?
Where the audio isn’t all the way to the left at 1.1?
If that’s the case you will need to render the audio files so that they have that gap of nothing in the files. To do this, one at a time solo each stem and do CTRL+ALT+R to render them (not sure if there is a more efficient way of doing this but that’s what I do). Use the rendered stem in Magma so now the audio files being used will have that section of nothing you see in Reaper and will then make it line up properly with the notes.
So basically the audio will go from this to this

If my understanding isn’t the case (or what I suggested didn’t work) then I’m not really sure and maybe a C3 Member could help.
May 23, 2014 at 9:13 am #420865Did you export your MIDI with the tempo map embedded?
May 23, 2014 at 2:45 pm #420885Thanks for the suggestions! Yeah you’re exactly right, I am using stems. When I imported each individual midi chart, (Part Guitar, Part Bass, etc.) I made sure to import each one exactly at 2.4 seconds. I’m thinking it filled in the empty gaps from everything before 2.4 when I consolidated the tracks, but I’ll double check as soon as I get home this afternoon.
When I exported the midi, I made sure to check the tempo map box too but like I said, I’ll double check that too.
Basically everything sounds and looks right on cue with the music, but as soon as I go to test it out on Rock Band, its like the notes are a quarter of a second faster than the music. I just cant wrap my head around why it matches up on the computer but not on the actual game. I know I’ve got to be missing be something.
May 24, 2014 at 3:11 am #420939Don’t rely on the preview too much. You have to account for audio latency as well. Your peaks have to align absolutely perfectly and when you Alt-drag the triangle cursor at the top of the timeline, the sound must match exactly where you laid the note. Usually it’s to the right of the gridline.
