I need to update my recording gear and need suggestions. I have an old G4 and 7.4 protools. Need to get in touch with this decade ha. I only do my guitar and bass parts here so fairly simple needs. Not sure what computer to actually get or what interface etcetera. I should have paid more attention during the last 10 years as we made our CDs in those big studios. Now I need to record my parts at home for an independent release and want to be cost efficient with excellent quality. Advise?
