There is a commercial version of MAutoPitch, but the free plugin isn’t crippled in any way, though it doesn’t have all the advanced features that the upgrade has. Being able to dial in wet/dry balance easily gives great-sounding automatic double-tracking (ADT) effects that are a breeze to adjust. Pitch correction has two general modes: subtle error correction and as a special effect, the so-called “T-Pain sound.” MAutoPitch handles both and then some. That it can be mentioned in the same breath as the leaders as a free plugin is impressive. I don’t think MAutoPitch outperforms either of these plugins, but it’s fast and easy to get results. Big-ticket pitch correction packages such Antares Auto-Tune and Melodyne can sometimes take some wrangling to fine-tune. In fact, ‘simplify’ is perhaps the best way to describe the MAutoPitch approach. What’s more, its interface is one of the most natural and intuitive you’re likely to find in pitch correction software, which by nature is difficult to simplify. One of these, MAutoPitch, is not only a great value at zero dollars, it’s got a few tricks up its sleeve that even the big players in the field don’t have.
Melda Productions offers a 34-effect free bundle that’s a tremendous package, particularly if you’re new to the plugin world.
