If you record music full-time in a professional capacity, you may have given some thought to Apple’s Logic Pro software (note: you’ll need a MUCH bigger budget than your average home studio recorder – the little Logic Pro app from the App Store is around $200, and the actual software is around $500). Logic Pro is high-end music recording software used by some of the world’s most famous recording artists, however like Garageband, there is currently no version of Logic Pro for Windows.
You’d probably be interested to know that these are the closest Logic Pro for Windows alternatives.
Alternatively, your other option is to try and find a version of Apple’s Logic Pro 5.5 or earlier, because back then Apple built the software for both Mac and PC users. Please don’t hold your breath waiting for Apple to start building PC versions of Logic Pro again though…seriously, it won’t happen.
