So it's not possible to get songs that Ie recorded before onto reason? Like I have songs from audacity that are just bass and guitar so I need to load them into reason so i can add drums. theres no way to do this? say I want to repeat a certain drum pattern for a few mesures and then repeat another drum pattern with a faster tempo afterwards. is there any way to do this or does reason only allow you to create beats with redrum that are all the same tempo for a song?
