Hey guys, I've been playing random customs for a while and have recently become interested in charting my own. I've downloaded the tools and started on one song. So far only the vocals are fully charted with the other instruments in varying stages of completion. I tried to test the vocals by exporting and playing the song in Rock Band and the game recognized the song and everything plays fine, no errors or anything. The only problem that I'm having is that for some reason the vocals start 1-2 phrases early than they should. In reaper the TRKS track has the song starting at 4 seconds like this:

The vocals are synced up in reaper. Is there something I'm doing wrong in the exporting or Magma building stage or something that's causing the offset? Any help or advice would be appreciated. I don't really know what I'm doing, so it's probably something really obvious. Thanks.

The audio that you link in Magma will start playing immediately when the song starts -- it doesn't know that you left a gap in Reaper. You can drag the left edge of your audio file in Reaper and export it to a wav file, and then use that in Magma.

Might want to put some cymbal hits in there while you're at it for lead-in.

This. Also, sometimes RARELY (and it's happened to me), the midi can get messed up visually when altering Time Signatures from 4/4 to 5/4 and vice versa. It looks messed up and a gap jumps in Reaper, and if you set your audio up perfectly then, it will be off my at least a half-measure. Closing and re-opening Reaper and re-importing the midi will fix the "jump" in the mid and your audio can easily be re-synced.

It's not a specific time signature change, it's for any time signature changes not properly set (in example, a time signature change set on the 3 of a 4/4).

Make sure the checkbox about exporting the tempo is checked when you export your MIDI, too. I can't remember what it is off the top of my head, but it's in that dialogue box. Given that your tempo is half the default (of 120 or whatever), that would be my guess as to the behaviour you're seeing.

Thanks for the replies everyone.

I tried accounting for this at first by importing the WAV into audacity and generating 3 seconds of silence, but it seemed to be even more offset. I will have to go back and add the cymbal hits to set the tempo though. I forgot to do that >.<

The time signature is straight 4/4 since it's a fairly simple song, so no problems due to time signatures.

I don't have access to my xbox during the weekdays since it's in a different town so I can't check, but I think you're right Espher. I went into Reaper just now and opened up the export MIDI dialog and "Embed tempo map" was unmarked. I'll try again with the new MIDI on Friday and see how it goes. Thanks again.

I had the same problem when I first started. What I do is use File/Render to render just the TRKS track. Click the "S" solo button on TRKS (assuming you are not rendering stems) and then render. Then in Magma make sure you use the rendered wav file. Make sure you have the volume up as it should be and the rate of the track is set to 1.0 since it will render it using whatever settings you have in effect at the time.

It was the tempo map problem. Thank you so much you guys. I have a different problem now though. Harmonies are charted for the song, but when I try to compile in magma it's giving me an error saying that the MIDI has 0 vocal parts. The solo vocals worked just fine; it's just when I try to add harmonies that it gives me this error. Any ideas on what it could be? Thank you again :D

We have go to release our template asap... Check the harmonies parts, the track name right now is PART HARM# (1, 2 and 3): that's wrong. It's HARM# (1, 2 and 3), no "PART".

Thanks :D. That fixed the compiling error, but now on the third harmony I'm getting errors that say that the notes are out of the phrase. Are there phrase markers to put in the third harmony? The markers are set for the other harmonies, but there's not a space for them in the third. Thanks again.

You put phrases in HARM1 and 2 only but those phrases must encompass all HARM3 notes too.
