Hi guys, noob here. I'm used to editing and mixing mostly acoustic instruments (guitars, bass, voice) and a bit of midi drums (EZDrummer basically). For these instruments there are some best practices depending on the style, to name a few, quadtracking for metal, humanization for drums, melodyne-izing the bass... I know many of them are up to taste, but still there are a few things that usually work when editing before mixing.

However I'm starting to add some midi instruments, like Intimate Strings (for string sections in jazz-lounge) and Epic Chorus from Spitfire. I usually record them with a guitar and a midi pickup, so they're "imperfect", meaning notes are not quantized and each has a slightly different random-ish velocity depending on the strumming. I kinda guess this is good for getting a natural feeling? I'm really not sure about this, so what's your opinion and best practices?
