Welcome to the crew, mate! Yarrrrr! etc. 
Working with hex (base16) isn’t as brain-destroying as it seems, in fact it’s extremely condusive to music making once it “clicks”.
Decimal:
00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22…
Hexadecimal:
00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10 11 12 13 14 15 16…
Instead of focusing on how complex it initially seems like “what the f#@!?.. why does 21 equal 15 in hex?!”, focus on the more simpler aspects which should hopefully already be standing out to you.
Important values such as 16, 32, 64, etc. now all fall on multiples of “10” which is quick and easy to work with. Even though both systems involve relatively simple multiplication, what can you figure out quickest in your head: “3 x 16 = …” or “3 x 10 = …” ? Those few milliseconds you save can be spent on making music!
If you’re working with 4/4 music and you want a kick drum on every beat, it’s very easy to see where you need to put them - it’ll always be on 00, 04, 08, 0C, or 10, 14, 18, 1C, or 20, 24, 28, 2C, etc, etc. Again, even if you’re not that great at doing multiplication in your head this is very easy to work with.
Same goes for other stuff like writing in volume commands. 40 is full volume, 20 is half volume, 10 is quarter volume, etc.
Anyway, hang in there. Tracking will become second nature soon enough
