For those of you using mp3+g files. I have finaly found a software that will change tempo and key and keep the video in sinc with the music. It will also allow you to merge songs and cut out the silence before the song starts and alter eq and other things.
when you open the zip file for mp3+g and run the software it makes a copy of the video at the same time at the proper speed so when it's done which takes about 5 seconds just create a need zip file and you are done. IT WORKS GREAT. The name of the software is
KARAOKE SOUND TOOLS 2. It cost $50.00 and updates are free forever.
This is the only softwhere I have found that does this and it works great.
