I am learning to play drums and have learnt a few songs. While I play the drums i record the music on my phone. I then decided to upload the drums to magix music maker so that I could add the mp3 of the song, line the two up and have my drums over the music. The problem I am experiencing is that even though I am playing along to the song and am pretty much perfectly in time, no matter how I line the song up, it always goes out of time and my drums end up being a bar and a half ahead of the track. there is no way I am playing that far out of time, and every time I check the tempo the speed of the song is different to the speed of my drums. I saw another question that mentioned something to do with latency as a possible cause but I am not sure. Any help as to how to solve this problem would be much appreciated. I am using magix music maker premium 2013, the songs are recorded on a simple recording app on my phone which records them in mp3 format, andt he tracks are also in mp3. I have windows 7 as well. many thanks
