This gets to really be a question of money. Less than $300 for everything they sell in 2020.
This is a lot of stuff for that amount of money.

After other software, computers, guitars, pianos and other music stuff I own BIAB is not a material amount of money.

Real Tracks for me are useful in many ways. They are a tool to learn new stuff from pro musicians and fun to mess around with for recording.

Midi is every serious musician's go to tool if you use a keyboard. The thing I like most about midi is the vast amount of really good VST's that exist today....many for free and some I own that cost more than BIAB. I could never own enough real drums to get all the sounds I get from VST's. Even if you are a pro drummer playing on the best pro kits, you are likely to trigger a VST from your kit.

Also it depends on what skill sets you have and what other software you use. I can edit in standard notation with a greater degree of precision just because I have better skills there than in midi editing. There is a serious time cost to standard notation not the least of which is learning to read, and of course learning to use a notation software program.

I don't think is is very easy to know what someone will find very useful unless they take a chance and buy the top of the BIAB line of products.

I would never dream of trying to tell you how to spend your money. I would tell you I have never been unhappy with all the stuff I have acquired from PG Music.

Good luck,

Billy
