Hi, I had a similar problem that was driving me crazy, until I found out what was causing it.
Make sure that all of your 4 loop files are in mono, and are of EXACTLY the same length.
Your M loop (that is assigned to the mix down channel) should be in stereo, and once again it must be exactly the same length as the other files.
Even 1 second’s difference and the loops won’t play from the 45000.
Also check that the txt file has the correct tempo (the tempo you recorded the loops to originally). You can simply copy a file from an existing factory loop and adjust the tempo in the text.
Good luck… when it works it’s worth the effort!
