I first encountered Regroover by Accusonus at the 2017 NAMM Show. Simply put, it blew me away. Here was a program that could take a stereo audio file such as a drum loop, and isolate and differentiate between the different instruments and hits, assigning each to its own track. The user then has a full range of tonal and rhythmic control over each track, as well as (of course) the ability to cut and paste elements from one track to another.
Unless you live in a lava cave in a techless remote corner of Iceland (which I've considered doing during more deadline-intensive weeks), you've come across the term "machine learning" in the news, and that's the key here. The program uses a type of artificial intelligence to make its decisions about what rhythmic element is what, then tease them out individually. It works remarkably well, though it should be noted that it works better on stereo files that consist mainly of clear transient information, i.e. drum loops as opposed to songs with vocals and full instrumentation.
The applications include remixing as well as crafting of entirely new grooves, and the just-recent update to version 1.6 adds the following new features:
- Sync-to-host for locking Regroover up to existing projects in your DAW.
- User-defined pattern lengths for producing new beats from pre-recorded samples, even if the length of the source material doesn't match that of the pattern.
- Ability to jam with new loops in Regroover while your DAW is playing.
- Modifiers for instant correction of tempo errors.
- Improved drag-to-pad functionality.
There are two levels of Regroover: Essential and Pro, which you can find out more about at the Regroover product page. In a nutshell, Pro offers more features for dragging hits to pads, creating your own kits, and integrating sounds both internal and external to Regroover itself.
Regroover Essential sells for US $99, Pro for $219. Both are Windows or Mac compatible and come in AAX, AU, and VST plug-in formats.
