Using Cubase is a very wise move.....albeit it has a big learning curve but mastering it is worthwhile in the long run...unlike some other programs Cubase is a non destructive recording and editing program.....in short everything can be undone and redone as nothing gets blown away or overdubbed permanently......each project has its own folder and each step in the process is stored in the folder so you will never lose anything.....it can be remixed re recorded or mastered anytime from any step in the process.
Tip one....Cubase requires a save folder when you start a project rather than like most programs when you want to save the finished project so always always always...set up a folder and NEW different file for each new project and make sure you date it, name it and know where it is....that way you can keep your stuff indefinitely and revisit it anytime you want. You can have many projects on the go and dabble as and when you want. I foolishly did not know this when I started and lumped everything into the one gigantic folder....big mistake.
Tip two always record dry on different tracks and only apply fx like reverb etc and compression etc as a last step before mastering.....cause if you decide to put in say another guitar part or harmonies then the whole thing will need re levelled and mixed.
