Ok so I've seen many people've had problems trying to properly sync scorehero charts the old way (chart2mid+dB+Audacity+offset+rightmp3/ogg/wav). So here's what I think is the easiest way to sync em.
You gonna need:ReaperRBN PluginChart2mid
Your Mp3/ogg/wav Obviously
Your downloaded .chart.
A few minutes to do this.
Ok so let's say you already know how to download .charts from scorehero right? You have something like THIS
Frets on fire don't allow .charts like gh3 so what we gotta do is convert that .chart to a mid file. So you're gonna open Chart2mid
and browse your .chart file. Once you've found it you click OK and should look something like this
Now your status should've changed to VALID which means that it is a correct file and you can proceed to convert it. There's 2 ways to convert it, the Guitar Hero way (guitar, bass, coop guitar), and the Rock Band way (Guitar, Bass, Drums), is up to you, although I'd suggest to convert it as a Rock Band mid if you ever wanna add drums to it or whatever, so now click convert. Here's how it looks the guitar hero way
Now you got your mid file which is the one we're gonna use for FoF and for Reaper. Here's how it looks (in case you're using WMP as the default player for mid files),
So now you're gonna open Reaper, grab your mp3/ogg/wav and .mid file
and drag them to reaper and should look something like this (make sure to drag em to the very beginning)
now click OK. Now it looks something like this right? STOP RIGHT HERE
You gotta make sure that Snap to grid is DISABLED. You might wonder why? It's because if you enable STG, you won't be able to move your audio to any position you want, STG only moves from position A to B if you disable it you can now move it to wherever you want. So ok now here's the only "hard part" (which totally isn't). First you gonna press SHIFT + F on the tab you wanna sync, in this case if you wanna sync DRUMS then select the PART DRUMS TAB and press SHIFT + F and you'll get something like this
Click on VSTi and then double click on VSTi RBN Preview (RBN) and you'll get something like this
Obviously I changed the background and did other stuff but that's not important right now. Now you're gonna click on that preview window what skill you want (most charts only have Expert), Easy, Medium, Hard, Expert, and what mode you want Guitar/Bass or Drums.
Now here's where you're gonna SYNC, you gonna move your audio tab to the point where it matches the first note (here's where the RBN plugin works like a charm), you can remove silence if there's any or add silence just by moving your audio tab. Use the metronome or claps or whatever you want to make it as a accurate as possible, reduce speed, wear headphones (A MUST). And there you go you have your chart completely synced. Now we don't wanna save the whole project cause is not necessary, what you're gonna do is go to FILE>Export Project Midi and you'll get something like this MAKE SURE ENTIRE PROJECT, ALL, MULTITRACK MIDI FILE AND EMBED TEMPO MAP are selected or else!!!
That's your mid file synced and ready to be played on frets on fire but you need the audio too, so what you're gonna do is go to FILE>RENDER and you'll get something like this AGAIN MAKE SURE RENDER ENTIRE PROJECT IS SELECTED AND YOUR OUTPUT FORMAT IS OGG
There you go, it's all done! Just change the name of the mid file to NOTES and the OGG file to GUITAR and then do the usual, just add an ini file or copy one from another song and change artist, song, fretter and whatever. That's about it.
I know this looks like a huge tutorial but it actually isn't, is just that I wanted to make it as clear as possible but if you guys got any questions I'll do my best to answer ASAP. There you go, once you've synced like 2 or 3 songs it won't take you more than a minute to get all your charts synced and ready to play em on frets on fire.
