Audio .cdg out of sync after splitting / re-joining

[EdS]

After splitting .bin karaoke files that I have made with KHPro, into .CDG + .Wav (I sometimes want to change the key of the song, etc.), the .cdg lyrics file is LAGGING the music upon re-joining. However, after splitting / re-joining commercial karaoke files, such as Sound Choice, there is no problem with the lyrics sync.

Why are you doing this when you can use Keyrite to do it without having to split it and it will keep the changed key music in sync with the lyrics?
It sounds like your program you are using to change the key is also changing the tempo.

Most of the time, I am changing the pitch ever so slightly, so I can play a piano along with the tracks and have them all in tune. I am using Adobe Audition and trust me - it DOESN'T change pitch an speed simultaneously anyway. I consider myself an expert with Adobe Audition, and the huge time disparities I am experiencing (3-4 seconds) could never be explained by any small aberration which might result from using Adobe Audition.

And, as I said, the commercial tracks don't behave this way. So ... would you folks please please look into the SongVerter program to see if it mis-interprets KHP's .CDG file info? I have spent a long time working on 300+ tracks to normalize them all to the same pitch reference (A=440) so it would be very disappointing to not be able to utilize the fruits of this extensive labor. I would be very grateful if you could help me out here.

The pitch shift you are using is non-standard and I doubt that there is anything MTU can do about it since there programs all use the same steps of shift for all their key changes.
Maybe the best way for you to do this is to make your pitch changes to the audio before you add the lyrics in KHPro. Then the combined file will be set correctly.
Other than that your best bet would be to submit a support ticket because I doubt anyone in the forums can offer you any help with it.

Pitch shift is not the issue here. And hind sight is always wonderful. The reason that I purchased this software was to help correct my problems that resulted from not being diligent in the first place.

I will submit this ticket you refer to, once I figure out how to do that. Thanks for trying to help, Ed.

Well, about two weeks ago I sent in a ticket, as you suggested, for help on this issue, and today, for the VERY FIRST time, I get this response:

[ Your ticket at MTU.com has been Closed and assigned ID: 16651-7330041325 ]

I NEVER got so much as a "good mornin' " from these people. That's not like the MTU I used to know. Not even a way to contact them, because it is from a "Do Not Reply" email address.

Eds, as MTUSUPPORT pointed out, we have never received a complaint to our remembrance that any song created with KHPro is non-standard CDG.

We first developed our Karaoke Pro software to work with our Microsound Digital Audio Workstation for one of the largest Karaoke Producers in the world. It was shipped July 30, 1999. After shipping that for years. We recoded the Karaoke Pro code to run by itself as Karaoke Home Producer (aka KHPro). This is a professional package.

I personally will create a song with the lyrics in sync to VOCALS in the music this weekend, export it as a BIN file, use Songverter to convert it to CDG+WAV, then convert it back to a BIN, and then play it to check the lyrics sync. I won't do any external processing as that is outside the scope of our tools.

I'll post back here Monday what I find.

We started working on Songverter 1.21 today, and this problem will be addressed.

Thanks for your timely response. I'll wait to hear from you.

Hi, Ed.

Here's what I just did:

1. Imported a new Karaoke track into a BIN file from a CD+G disc using Microstudio
2. Played the BIN file to ensure it was in sync (and it was)
3. Converted it to WAV+G using Songverter
4. Renamed the WAV & CDG files, to ensure the original wouldn't get overwritten
5. Converted the WAV+G back to BIN using Songverter (new name)
6. Played the new BIN file, and it, too, was in sync.

I know I didn't follow your steps exactly, but this should prove that Songverter will split a proper BIN file into WAV+G and then restore it back properly.

Next, I will try inserting KHPro into the mix and report my findings back here. Don't touch that dial!

OK; we are, so far, on the same page. You will note my first posting that commercial files present no problems to me. It's only the ones I make with KHPro. I am repeating my first post here:

"After splitting .bin karaoke files that I have made with KHPro, into .CDG + .Wav (I sometimes want to change the key of the song, etc.), the .cdg lyrics file is LAGGING the music upon re-joining.

I like being on the same page. So, maybe it's not Songverter that is at fault here. Maybe it's KHPro. Or maybe it's the key-changing software that you are using. Have you analyzed the original vs the key-changed WAV files?

Today, I will create a perfectly-sync'ed BIN file using KHPro. I will then split it into WAV+G and rejoin it back into another BIN file. I will post my findings here.
