This so much. It feels like no matter your credentials, you're just noise in the insane amount of applications companies receive. Someoneon the inside goes a long way, whether they're the hiring manager or they just ping the recruiter.
I'd say most performances on these are accompanied by a DAW. Then you just record it and re-use sounds between performances. For some instruments/tracks you probably want the freedom to play it live and accept that it sounds different between performances. In fact that's the whole appeal of it in my opinion.
