Extra screen for combining Audio waves!

I’ m writting to you because of the problems i had (for IPAD version) with syncing songs. It would be easier to make an extra screen above, that combines both audio waves to make better sync! So you can see the wave beats move together…
Please make it REAL!

Yes this would be the best and something i have emailed about adding. Just like Serato NoiseMap would be perfect. This would make life easier
