everybody welcome I'm going to go over a technique that is new to reason 7 and that is the ability to create Rex files right within reason so if you don't know what a Rex file is Rex file is I don't know top five great things to happen in the music industry of all time depending on how you work and you know what you do Rex files are created by a program called recycle which was released by propellerheads in 1994 that program is almost old enough to drink in California that is quite a thought that is rarefied air in itself that propeller has been around that long and is still thriving and probably doing better than they ever have in the past so when recycle came out it took every problem that a lot of us had when we worked with samples and the truth about samples when you load a sample a bit of audio into a sampler when you play it higher up on the keyboard than its original pitch it is faster and pitch and is higher in frequency and if you go down the keyboard it is lower and slower so you could not separate tempo and pitch and from somebody myself that actually did a fair amount of sampling for hip hop back in the 90s this was always something that goddess and I remember when recycle came out and it was a game changer so recycle would analyze a file you would give us some basic parameters you know how many bars and beats just a little bit of setup and then you it would analyze you would set sensitivity and if this sounds familiar every other program on the planet has snaked this technology even so much so they'll say well this is a recycle like function we've built into our program so you would sense it you would give it a sensitivity level that would then look at the transients and eventually cut that audio file into slices on the transient so the biggest power of this might have been the simplicity you know a lot of times people say some of the greatest ideas are the most simple ones and you know this truly was because at this point we could move slices further apart slow down the tempo move slices closer to to speed it up and not change the tempo there is a are the pitch there is a pitch function in recycle if you wanted to use it but they were not connected for the first time so every program I believe I think it's like twenty three program supports the import of Rex files the use of Rex files so valid audio file type and the magic of that Rex file in almost any DAW is that can flex with a tempo change right so it's audio but it acts like MIDI pretty cool stuff been around you probably know very well what a Rex file is so reason because made by propellerheads same company that made recycle has always had one of the best utilizations of rex files and that is the dr. octo the new version of it the Rex player or the octorex because they're the company behind it of course the way that Rex files can be used in reason I think you know are way better than any other program and it's like I said it's not that you can't use them in other programs it's just dusts its own base for this file so other videos that we've done have you know how to really use the Rex player so that's not really what we're looking at today and you can search for those and I know propellerheads website has some of that as well but this is what's changed in reason seven propellerheads baked in the ability to make a Rex file right in reason so you no longer need recycle to make a Rex file remember that the magic is the power is that it separates tempo from pitch and an audio file and it means it will respond to tempo changes with your master BPM so you've got a guitarist plays a guitar part in you think ad that's really cool but I want to go ahead and you know I'm going to change the tempo from what it was recorded at well you know most programs honestly these days have flex have warping have elastic audio all these are math or algorithms that go on the audio and it does affect the audio quality certain programs that effects it more than others if you know what I'm saying not going to mention any but it's an algorithm or Rex in recycling and a little love to beat detective in ProTools those are ways that we can actually slice up the audio into little bits and then move them closer further apart edit them change them do whatever you want but it does not affect the audio quality so wreck Singh beat detective in there's such a word are ways that you can keep 100% fidelity of the audio one day algorithms will probably be as good and maybe even better and they're certainly quicker in some ways but you know just to throw it out there anytime you quantize audio or you warp it or do whatever you are affecting the quality and I know that some of you have heard this before actually hearing the kwatak quality be diminished so Rex is a great tool to be able to use for this but it also gives you the ability when you put a Rex file to a track to get the individual slices and have your way with them so you can remix a loop of audio no problem because each part of the sound or each sound is one slice and you have the ability to do what you want with it so I'm going to go ahead and get rid of that Rex prayer real quickly we're going to go ahead and make one so I have a little bit of a drum beat with redrump going on here
right so it's MIDI in most the time you know if we think that's many why would you even turn it to audio I'm kind of doing it just so we can see the process without recording a guitar but I also think making a Rex file out of anything is cool if I could make a Rex file out of my espresso machine I would probably do it so the way that we turn MIDI into audio in reason is thus we find the device we want to record we open up the mix channel device from this view to this view and we hit record source this basically means we can now record from this mix channel to an audio track we go back to the sequencer I have an audio track here that's just command T and reason and I set my IO right here so I'm going to tell it stereo and now it sees that if I had not hit record source on Reed drum this would not be a be available so I choose that I'm going to record enable it I don't want to record over my MIDI part so basically I'm just going to make audio real quickly alright so there is my printed audio I'm going to go ahead and mute the Reed rum I'm going to double click and zoom in just a little bit this is another great thing about reason and I think we've done some videos about this that everything when you record audio in seven everything is auto sliced right that also gives me the ability that I don't need right now because those drums are pretty tight that I can hit command a and that's going to select all of those slices and I can hit command K and that's going to quantize that so the ability to quantize audio once again using math does exist in reason and I have to say it's one of the best programs it's algorithms it's math is really really really good those suites know their math alright so I don't want to do that but this gets me to what I want to do which is right-click so that was a double click we go back out of that so it was a double click get to this view go ahead and right-click and go bounce and now only because I did that double click from the first window do I get bounce flip to Rex loop now the tool window up in the top right watch what happens immediately it sees print which is what I called that audio I can hit the disclosure triangle and we should see a bunch of slices so that's just what Rex's look like with inside their file type and I'm going to double click this that's going to auto create a Rex player and we're going to hit run and there it is and if we hit this disclosure triangle we will see the editor and there's all the slices so from that original drum machine pattern it is now audio it is now a Rex file and of course slice edit mode which is just awesome gives me some great abilities
right so each slice has parameters that you can control so not just the whole file each individual slice so right they're worth the price of admission I love the octo Rex and I love that slice edit mode remember that has to be turned on now I can go a step further and I can hit copy loop to track we go back f7 to the sequencer and there is the Rex files I'm going to mute now my print audio track and here's what it looks like to track I can scroll up and see it one of the things I hit if you noticed when I was in the Rex player was alt you get four different alt groups and what it means it's going to randomize each of those slices as you play well we actually see that physically manifested in the sequencer here's the randomized parts otherwise you know Rex files have kind of that Universal 45-degree angle each slice represents one sound I can actually play it from my keyboard if I'm targeted on that so Rex can be targeted from the keyboard you can play you can replay it I could go in at this point now though and I can quantize I can move around I can delete once I get those individual slices to a Rex track I can do whatever I want so if I go back to the Rex player I do have to turn on the ability for the velocity to take hold it defaults with the amp at zero so this will actually give me velocity I can go back in here now and I can take my pencil tool and I can kind of draw in some other velocities of course if we're really working we take a little bit more time and we get and before I play it actually remember my manners which is turning off the loop playback otherwise we will target the same material from two destinations and we will phase and it's not a pretty sound
and there it is so in reason we can now make our own Rex files from audio vocals guitars anything rhythmic it's always easier to make Rex files out of something with defined transients so rhythm guitars vocals acapellas for remix it does not have every feature that the actual program recycle has but it's a blast to work with Rex files slice dice cut-up do whatever you want with them so hopefully this will help with your production and I will see you soon very much like to thank very much posting me here once again I think this institution is really cool and until I came here for the first time I had never seen anything like it in my whole life what I think really separates us from other people who teaches that we are outrageously passionate about what we do and especially in electronic music since since founded pyramind I discovered electronic music and you know San Francisco being a mecca for underground electronic music opened up so many doors for me and kind of blew my mind we cover everything from absinthe to contact when people get to the mind melting level we get into modular synthesis everything about Native Instruments and everything about logic cents down to the finest detail we learn at all the fundamentals of understanding how things work that's just essential but then beyond that there's so much more and that's where it gets into just a lot of the artistic side of life the creative approach of why you do something not just how there's a lot of schools that just know they focus on the technicality of recording music but I wanted something that would foster creativity and and really help me develop as an artist as well each of our genre specific programs comes in four levels there's a basic and advanced a professional and then a master's level and the master's level is of course everything we do it's the largest most powerful programs that we can create for you

In this tutorial, Reason-Meister Steve Heithecker shows how you can use the famous REX files in Reason 7 without actually needing ReCycle. Historically you'd need ReCycle to create Rex files but Steve shows you how to bypass that function as well as showing you some great tips in the Dr. Octo REX.
