GrooveExtractor transcribes a drum loop recording into five components: bass drum, snare drum, close hihat, open hihat/cymbal and tom-toms. The transcription result is represented as General MIDI file. Extract the groove you like and turn into your own creation.

The main features are:

  • Three analysis mode: Electronic, Acoustics and Trigger.
  • Notes editing (add, move and delete).
  • Audio and MIDI playback.
  • Tempo estimation.
  • MIDI velocity.
  • MIDI file export.

You can export the transcription results to your DAW/sequencer by simple drag-n-drop or you can use the real-time MIDI playback to trigger the drum sounds you like. There are also handy settings such as Sync tempo to DAW while exporting and MIDI note mappings.

Groove Extractor by LeSound miraculously transcribes drum loops into individual general MIDI file instruments: bass drum, snare drum, closed hi hat, open hi hat/cymbals, and toms. Did you ever have a great groove, but wished you could substitute the kick, snare, etc.? Well, you can with this software. Use your "found" loops to get a track going. Translate into MIDI. Tweak as needed. Trigger your own kit. BAM!.

Groove Extractor features an attractive, user-friendly interface with a simple workflow that yields powerful results. The transport is basic, but includes exactly what's needed. .. no more, no less. In action, users either browse or drag-n-drop an audio file loops (or folder of loops) and allow the software algorithms to do the work under the hood. Within seconds, loops are divided into individual instruments on their own respective MIDI note numbers. Results can be exported, edited (if needed), copied, pasted, and manipulated endlessly into a creative bliss.

• Does it really work? YES!
• Is it perfect every time? NO! But.. .

Some loops are deciphered more accurately than others. It seems to depend on the recording quality, type of kit, and instrument positioning. Clean loops with instruments tonally where they should be = clean transcription. Yet, almost all transcriptions I demoed were useful. Some needed a little editing. Users can help processing accuracy by zeroing-in on the appropriate type of loops, i.e., Electronic, Acoustics, and Trigger (detects onsets). In my limited experience, I've noticed that acoustic "real" drum loops translated more accurately than electronic. I have a theory as to why. .. real drums instruments are easier to identify as they have a more distinct timbre and frequency range. Electronic drums, on the other hand, have a wider variety of tone and often share frequencies. For example, many electronic kicks and snares sound fairly similar except for a bit of added resonance or pseudo "snare" quality of the snare. In addition, acoustic drum loops are usually played by humans with human limitations, whereas electronic loops can be super human with no boundaries. However, some acoustic performances are complex with more percussion, and some electronic sequences are more straightforward and minimalistic. So, most of my hypothesis is pointless. LOL. Regardless of drum instrument type and performance, Groove Extractor earns its keep, cutting hours of suffering down to minutes of tweaking (if needed).

• Clean, easy-on-the-eyes GUI
• User-friendly
• Fun to use
• Surprisingly accurate
• Good browser
• Great tool that saves time
• Note/velocity editing
• Tempo estimation
• Forward-thinking, responsive developer
• Good price.

• Stand-alone version.

I love this software. It's perfect for my workflow and will certainly help me complete tracks. I will no longer have to spend hours struggling to recreate the vibe of a groove in MIDI form. It does exactly what it claims to do, and the price is right! If my virtual house caught on fire, this is one of the first things I'd save from the blazing inferno. I give Groove Extractor two steady hi-hats up. Check it out! In the meantime, I'll check out the rest of LeSound's bundle to see if they are a one hit wonder or. .. much, much more.
