Bassment

Hey, guys. I paid $30 for some tabs, but they're way too hard for me to work out. It's mostly the timing I'm struggling with (I'm used to yousician and songsterr telling me when to play a note) and my ear isn't good enough to work it out just from listening to the original song. Is there any software that can either output the audio or even just add a timing guide like songsterr? Thanks.
