Don't wanna hate on midi ,I have used sounds that worked . But in my opinion RT's sound better to me . I have and use some expensive VSTI's and no free ones ,also a MAC with Logic Studio Pro . All have some great midi sounds ,but pale in comparison to PG's new tracks . Logic has ton's of wav based loops that still sound better than their midi . I only say this because when I have brought tracks to sell at studios when it's midi based they say they don't want any Biab songs. When it's RT's they love it . Still only my opinion and people buying my tracks . Sorry if I have ruffled any feathers , I meant to offend no one .
