Not with my own drums, but I have found myself playing in bass or guitar parts, then bouncing them straight to rex (from the timeline, how cool is that?!), and triggering then slices back in different orders.

The guitar part on this was done that way.

I also find myself using octorex as a quick way of adding a bit of rhythmical texture; shakers, high hats, percussion. The fact it has a filter built in is a bonus, filtering out the lows, then slowly bringing them back in. And separate audio outs it pretty cool.

More recently I got into the 'Alt' feature, where you set different slices on matching channels/numbers that alternate. That's quite a powerful tool, and you can get some crazy effects if you push it.

Nice stuff Nymphomation
Yes bounce to Rex is a dream come true
Also the slice edit stuff is so fun

I never even knew about the notes to slot thing...amazing! I'll try out this "alt" thing next. I'll be honest, I always kinda skip Octorex. I wish they had've kept Dr Rex in there, the same way they've kept the NN19. It's a bit overkill when you want to just play a loop. But I'll take the time to learn it. Sounds like I'm missing out!

I typically use it for some additional percussion above a ReDrum groove. At other times I find a loop to build a foundation around, perhaps with a bit of tweaking to remove the worst sense of guilt from not creating the groove from scratch. Probably nonsense to think along those lines, because as mentioned above, the right loop can inspire the idea that otherwise wouldn't surface.

If the question is "why use rex files instead of just time-stretch loops," my answer is that the rex format preserves the original transients, which for a lot of things is most important.

I also love the ability to run a loop in pattern mode but program snare fills via MIDI. Or send notes to track and re-program, as many have stated. Or sometimes I drop the slices into redrum. It's a great format.

I use it with different loops to change between them to create a non static loop sequence

I haven't used it much so I'm probably missing some things, is the main attraction the way the midi clip is laid out in the sequencer?

What benefits do you find with using it over audio clips or CV / midi triggered drum machines for instance?

When I have drums I already like, is there much benefit to bouncing them to .rex, perhaps for stuttering or something else?


Cheers! :comp:

Hi, it used to be the thing back then when reason didnt fully handle audio. Still cool now though for creative stuff.

Cuz it's integrated into reason and handles chops like recycle does.
Can also be used as a clip launcher.

I use it mostly as an extra drum kit. Load up a loop, turn off run and record a pattern on the keyboard with the slices. You can get really creative manipulating each slice.

I find that I use it's built-in amp envelope a lot these days. Small tweaks to soften the attack & shortening the decay makes a massive difference in the sound & groove. It's basically a builtin transient shaper, right? Automating them both for builds & different parts can add dynamics to a track. Also I make deep use of slice mode, doing micro pitch adjustments (I really wish I could zoom in or even type a number to have tighter control of the pitch/per slice adjustments). I also like to reverse the odd slice or two. AND I will sometimes build really creative grooves by having multiple Octos playing different loops, but in each loop I use slice levels to remove hits from them so that when they all play together (with only maybe 25% of their hits enabled) it creates an unpredictable but totally locked-in groove.. I've come up with some great beats that way, and it feels almost like a treasure hunt doing it this way.. Fun as hell!

I should add, when I use the Octo, it's always in the form of a custom combi I made that has several levels of saturation & coloring at the ready. It also comes pre-wired with a CV splitter connected to the LFO, and boy do I make ample use of that (& it's inverted signal). I have several of these octo-combis in my starter template in fact. And believe me, I've spent years learning how to manipulate the f*** out of these loops, they don't often sound like "just some loops". Especially with automation. That device along with the Kong are a match made in heaven in my opinion

soundwise there's a difference. rx2 in audio lanes are time stretched as audio files. in OctoRex they are loops.

rx2 still sounds the most snappy. also in Ableton Live. most percussive.

must say that for more complex and melodic sounding audio, OctoRex will always introduce pops. it even happens on drumloops but there's always a slice cut in sustained sound. but it can be a cool artifact as well, sounds a bit like vinyl

i was going to use it but i found grid 64g though on really dazed days the rex is quicker to set up and not so wild

I like to take the gate output on a drumloop and trigger a bass synth - just change the oscillator frequency to whatever you want. This triggers a bass note with the exact same rythym as your loop. Change the loop slot, the rythym changes with it!

I do this too, but via Robotic Bean Step sequencer

Enter a bunch of note values into Step, set sequencer mode to whatever suits (I like Reorder or Random for leads/plucks). Then take gate out from Dr Octo Rex --> Step clock in/out --> synth gate input

Take CV out from Step --> Lectric Panda Janitor CV Shaper --> Ochen K CV Tuner --> synth note input

Tweak scale & offset in Janitor until you have the spread of notes you like, choose your scale in CV Tuner

(If you don't have them, Janitor is free and CV Tuner is $9.00 - Step is currently $35 which is an excellent deal)

You're starting to get fancy now lol

I share kind of the same feelings. I own all of the groove monkee Mega pack and the rex loops while nice aren't really named that friendly and I still would have to by ear categorize them as intro's, fills, verses or chorus where as with midi drumloops I can send them to any machine I want. This project I doing now I'm actually exploring REdrum. because I never explored them before. Typing in dumbeats becomes a very time consuming task and its complicated enough just to build a song. Rexloops I haven't yet figured out how to incorporate them in a serious flow.

I have always felt it would be interesting to create song with just rx2 loops. Create your own loops from your own recording. Slice up your music and rebuild it into songs. Because of the slicing and the new possibilities and because of the artefacts I think this will be cool.

Should definitely do it one day...

Why do you need CV-tuner if you have Step? You can tune your CV to a scale of choice using Step's input at the back...

I use Octo a lot, too...probably in 90% of my tracks
like grifty, I use Recycle to create rexs ; Recycle is just so much more functional (especially zoom) than manipulating audio in Reason, imo/e

I don’t have any special uses in mind to share...everyone else has covered most of those uses

the last project I delivered was a sound a like with glass and crystal hits. I recorded into my other audio DAW and comped; sliced in recycle and re-tuned and filtered in DOR. DOR was the best best tool in Reason for the task.

I also vote for fast drum part creations to get on with the writing. It doesn’t get much more simple than DOR...especially using the slots

It's so he can shift the scale and notes in ways that Step can't.

I've made a combinator with the setup that dvdrtldg described. You can load different Dr Octorexii and record the Step and change the instrument. This combi is a pretty fun starting point!

You can use Dr Octo Rex as a drum replacer : just choose different outputs for the slices you want to replace and with CV trigger you can trigger other sounds for these slices, that you have loaded in a Redrum for instance...

Is there any way to use the Filter of the Antidote (not the Filter Envelope) on a Rex Loop?

1) I like the "Gate Output" CV out on the back. It's great for a trigger.
2) I like randomly play the slices with a step sequencer.... put a Matrix below it and randomize the pattern and see what interesting results you get from Rex.
3) I like to rearrange the Rex files via the "copy loop to track" button, then go into the sequencer and rearrange the slices. You can also do some cool stuttering this way. It's great for experimentation or rearranging your riffs/basslines/drum hits to get some new alternate versions.

All that being said, I don't use DrRex as much as I used to. I used to use it a lot way back in the early days, before Reason had audio recording. I used to spend a lot of time recording my tracks and the turning them into Rex files via Recycle. That was a very slow way to produce and I dont miss it. I don't even have Recycle installed anymore.

No, you can't . The external input of Antidote is hard wired to enter the chain just before the effects. I hate it when synths don't allow for use of their filters by external audio. I'm not sure what is behind this decision but it seems to be a fairly popular choice. Seems like the audio input should enter the chain parallel to the oscillators, to me. Devs: if you are going to go through the effort to include an audio input to the synth, why not give access to filters and amp/env? Doesn't make any sense to me.

Rex to Melody.zip

Bad ass patch you made there. It sounds killer. Great example of how to use the Gate Output of DrRex to create a groove. Which is probably my favorite use of DrRex since i don't really use loops.

quite often i use it to spice up a beat etc... occasionally I chop one of its beats up in the sequencer and build a song around it. i don't use it as much as i used too, but now im thinking of it and really wanna go and use it... and like people are saying its filter is great!! im always automating the filter

Thank you very much for your answer Challism,

then the only way to use an external filter on Dr.Octorex seems to be with the Malström, because of it´s shaper/filter Audio Routing, but it´s not that effective than the Antidote Filter, bad luck for us
