In a previous post, Mo Volans explains how to add groove to our beats by using the Regroove mixer in Reason and Record. This is an indispensable tool when creating your beats and today I want to take this concept a step further and show you how to extract groove "mappings" from loops in order to apply them to your own tracks.

The first question you may ask is, Why would I want to extract the groove from a track? The simple answer is that as a computer based producer, your goal is to get your MIDI tracks to sound as natural as possible and the easiest way to do this is to have your MIDI tracks "line up" with something that already has that natural feel.

Now although that is a very simple answer and does not go into the mechanics of MIDI timing, this answer and the following exercises should suffice to convince you. Additionally it's great fun to learn how much power is at you hands with a little snooping around.

Today I am going to show you how to extract the groove map from an already existing Rex file in Reason.

Step 1

Let us First add a Dr. Octo Rex to our Rack.

Step 2

Next let's open the Reason factory sound bank by clicking on the folder icon on the Dr.Octo Rex and select Dr.Rex Drum loops.

I am going to select the Abstract Hip Hop folder and select Trh10_Herblize_090_eLAB.rx2.

Step 3

Now what is important to understand about this file name is that number in the name tells us what the tempo of the loop is. So we see that the tempo is 90 bpm. Let's set our sequencer to 90 as well. Doing this does not affect the groove we are extracting but it does keep the playback accurate to the original file.

Now with the Dr.Octo Rex Programmer open let's press the Copy Loop To Track button.

Step 4

You will see that I have copied this loop for 2 bars into the sequencer.

Next we want to pull up the tool window and select the 3rd icon in which is called groove settings.

Press the button at the very bottom that says Get From Clip.

Step 5

Now we need to name and save our groove template. Press the save icon in the groove window and precede to name and save your new .grov file.

That's it for making .grov files to be used in Reasons Regroove mixer via rex files in Reason 5.I have included the Herbal.grov file for you to play with, add to your collection and just experiment with.

Now of course we do not want to limit ourselves to only using grooves from the Reason factory sound bank so in my next post we will delve deeper into what it is that actually makes these groove mappings work and, how to make them ourselves from grooves we like from pre-existing recordings using Recycle.
