synchronising tracks

If you need to sync (align) the tracks you can do that in any DAW editor eg: Cubase, ProTools, Reaper.
In the Reaper if you need you can disable the Snap to grid setting, which provide easier more accuerate alignment [Options–>Snap/grid]
When you ready with the editing and alignment, you just need to export the tracks to mono wav files, [File–>Consolidate/export tracks] then open this files with uTool for creating multitrack song for your LP-16.
