Just buy it

I screwed around with the lite version for about 5 minutes before buying the full version. Sure it’s a bit of a trick, but the full version is absolutely worth a few bucks. There’s a learning curve. Tutorials are polished. It just works. Exceeds expectations. Does a lot more than I need it to do.

This app is worth every penny!

If you only received the Guitar fret board ... and the many types of guitars 🎸 this would be worth the $$$ But then the KILLER DRUMS... My, they sound amazing! The bass sounds this has... then to top it off you get the effects, And (if all that didn’t sell you yet) YOU CAN WRITE YOUR TAB, AND PLAY ***in real time***
5 THOUSAND stars

My only critique is that they should add the ability to apply swing/triplet/3 notes like how you are able to switch from 16th notes to 32nd notes. Other than that, this app is absolutely fantastic and it has taught me a lot about writing instrumentals.
