Hi,
I've been using Logic Pro since early 2012, for production, writing, recording, mixing, editing and mastering.
I studied Logic Pro X as part of my course at The Academy of Contemporary Music in Guildford, UK.
There's not a lot of things I can say other than that I can teach your son a lot of Logic Pro, both software-specific skills and general ones, that apply to any software he might use in the future.
Additionally, we could tweak the curriculum to include mixing as well, if he wants that.
Best regards and God bless you,
Tiki Horea
