24 – A few No-Nonsense Tips

In this tutorial I’m going to outline some of my favorite quick tips that you can use when you find yourself in a bit of a bind with Reason. Hopefully these little tips open you up to a new way of thinking with the software, or else at least point you in the right direction if you get stumped.

In this tutorial I’m not going to outline any grandiose Combinator or showcase some majorly complex CV routing scheme (though I have a few interesting ones that I may show down the road). Instead, I’m going to outline just some of my favorite quick tips that you can use when you find yourself in a bit of a bind with Reason. Hopefully these little tips open you up to a new way of thinking with the software, or else at least point you into a direction in case you get stumped.

All of the tips below came out of a need I had to get out of jail with the software. In other words, I’d find myself at a standstill unable to go further because I’d locked myself in a hole. Here’s a few ways I found to get out and escape. I hope you find these tidbits useful.

Tip #1: Unison = Stereo (It’s not just big fat sound).

The first tip came out of a post I’d seen on the PUF (Propellerhead User Forum) entitled “Confessions.” In this post, a few people had stated that they never used the Unison device, and didn’t really understand what it was for. “I think it has something to do with fattening up the sound, but I don’t really use it and don’t really know what it’s for.” Fair enough. Here’s what I think:

Yes, it fattens up the sound. But it does more than that. For instance, take any monophonic sound device; The Subtractor and Thor come to mind. If you start playing either device, you can tell it sounds monophonic. In the case of Thor, you can do some clever things like add some Chorus and Delay. Perhaps in the Subtractor, you’ll add some ring modulation or FM synthesis, detune two oscillators together. But here’s the dilemma: you add a Stereo Imager after the device and nothing happens? Why?

This is because the Stereo Imager only works on Stereo audio, and since you have a device which is monophonic, nothing is going to happen. The simple fix: add a Unison device between the sound source and the Stereo Imager. Instantly, you’ve turned your sound into a Stereo audio pair going into the Stereo Imager, which can now effect the sound as you want (point of fact, it’s more of a faux stereo, but it works).

The unison device is there to “Stereo-ize” your monophonic sound. At the same time, it fattens the sound by creating multiple detuned voices out of the audio you send into it. Good enough!

Tip #2: Mixer Pan/Level CV automation is holding me back!

Ever automate the level and/or Pan info on your main mixer in Reason or Record and then realize you can’t alter it at all. For instance, if you send a Subtractor LFO to fully automate the level of your track, you end up unable to alter or change the level to fade it in or out right? Whatever is playing in a clip in your sequencer will be affected by the LFO as is. No fade ins, no fade outs, no changes along the way. Same goes for panning.

Here’s a simple tip to allow you to have both. And again it involves inserting a device between the sound source and the mixer. In this case, it’s another line mixer. Insert a 6:2 mixer between your main mixer and the sound source. Then flip the rack around and move the audio cables from the sound source into Channel 1 on the 6:2 line mixer. Then send some audio cables from the main output on the line mixer into the previous channel on the main mixer. Now you can flip back to the front again and right-click on the Channel 1 level knob, select “Edit Automation” and enter your fade-ins and fade-outs. You can also adjust your panning on this line mixer as well. This will affect the panning of the sound source before it gets sent into the main mixer where the CV is affecting the panning. In this case, the panning is combined together.

There you go. Total control over your mix, even when your mix is being controlled by CV.

Tip #3: While we’re on CV, don’t forget you can automate any CV trim knob on the back of any device

I discussed this tip in full here: #7 – Adjustable CV, but it bears repeating. If you want to control the trim pots for any CV connection (you know, the tiny knobs on the back of your devices into which you send the CV cables), simply insert a Thor device between the CV source and the CV destination. Route the CV into the CV in 1 within Thor, and send it out from CV out 1. Then in the modualtion Bus Routing Section of Thor (MBRS), use CVin1 as a source and CVout1 as a destination. Enter 100 as an Amount, and then use Thor’s Rotary 1 as a Scale (also with an amount of 100). Put everything (source/destination devices as well as the Thor “CV Pass-Through” device) into a Combinator, and program the Combinator’s Rotary 1 to adjust Thor’s Rotary 1.

This means that you’re adjusting the Scale amount value using the Combinator Rotary 1. Essentially, this will have the same effect of adjusting your CV trim pot. Sounds complicated, but it’s really quite simple.

Tip #4: Damn it, there’s no CV connection. But I want to automate it with an LFO!

Enter the Combinator to the rescue. For this trick to work, you have a device which has a parameter you want to affect with an LFO (or any other mod envelope or anything you like) and the device with the LFO which is going to affect it. This couldn’t be easier, but it’s not at first obvious. Here’s what you do:

Put both devices in a Combinator. Flip the rack around. Send the CV from the LFO device into the Rotary 1 CV in of the Combinator. Then flip back around to the front, and open up the Combinator programmer. Select the sound device. In the Modulation Matrix, use Rotary 1 as the Source andthe parameter you want affected in the destination device as the “Destination.”

Now, when the LFO is enabled and running, it gets sent along the CV cable and affects Rotary 1 on the Combinator. Rotary 1 on the Combinator in turn is affecting the parameter on your destination device. In other words, the Combinator Rotary 1 is used as a CV pass-through to affect any parameter you like, not just the ones that have CV slots on the back of the devices.

Tip #5: That nasty bypass click.

Not all glitch sounds are good sounds. Such is life when you are dealing with bypass switches in Reason. Sometimes you’ll get this nasty clicking sound when switching from on to bypass or vice versa. Sometimes you’re lucky and you don’t get it. It’s like Russian Roulette audio-style. This is why I never ever use the bypass switch. And also why I never ever automate it. Instead, here’s a few simple ways to get the same benefit without the horrible clicks.

First off, if you’re using a device that has a dry/wet knob, put it in a combinator and tie the dry wet knob to a button or a rotary. There’s your bypass button.

If, on the other hand, you need to get around bypassing an entire Combinator, try this trick. Inside the combinator create a spider and a second line mixer (assuming you already have a line mixer for the main audio). Then split the audio coming into the combinator, and have one split going to the main line mixer and the other going to the second line mixer. Merge the master outputs of both line mixers in the merge section of the spider, and then back out to the Combinator “From Devices” output. Ensure all your FX and Instrument devices go into channels on the main mixer. Leave the second mixer for the dry signal only, and nothing else.

In the Combinator programmer, program a button to switch between the two mixers. So when the button is off, the master level on the main mixer is at 0, while the master level on the secondary mixer is at 100. When the button is on (lit), the master level on the main mixer is at 100, while the master level on the secondary mixer is at 0. The button now acts as a bypass. When off, the signal is bypassed and the audio goes right through the Combinator unaffected. When the button is on, the Contents of the Combinator are enabled and the sound affected can be heard. Instant bypass without any clicking issues.

Keep in mind there are some things that just can’t be stopped on a dime. For instance, changing the delay time or automating changes to the delay time will result in a very distinct sound, almost like a pitch shifting. You just can’t get around this. That’s the nature of audio. So while bypassing most things works without any side effects, other things can still be noticeable. The idea, however, is to minimize the unwanted audio problems as much as you can.


I hope you found these tips useful. I’ll keep posting more as time permits. In the meantime, feel free to share your thoughts or your own tips here by posting a comment. Happy Reasoning!

Mono, Poly and Stereo

This article will explore Monophonic versus Stereo and Monophonic versus Polyphonic. Two very different concepts, but both very important concepts. This is also a good opportunity to discuss the Effects devices and go over the suggested audio routing options for each.

This article will explore Monophonic versus Stereo and Monophonic versus Polyphonic. Two very different concepts, but both very important concepts with which everyone needs to get to grips. The reason I’m going to explain them both in one article is because they have similar terminology (they both share the term “Monophonic”). This can lead to some confusion. This is also a good opportunity to discuss the Effects devices and go over the suggested audio routing options for each. 

When I originally put together my Reason wishlist and posted it here on my blog, I made the fatal mistake of saying that I wanted the Matrix to be “Stereo.” I actually meant to say I wanted the matrix to be “Polyphonic.” Oh gasp! I know. The horror. So just in case anyone else is confused by these terms, let’s see if we can set the record straight. 

First, there are two concepts: 

  1. Monophonic versus Stereophonic: This refers to channels in an audio system. Monophonic is 1 channel (or any single-channel system). Stereophonic is a two-channel system (left and right audio channels) which are reproduced by 2 speakers (left and right).
  2. Monophonic versus Polyphonic: This refers to the number of voices that a Synthesizer can play at one time. Monophonic means the synth can play a single voice (single note). Polyphonic means the synthesizer can play multiple voices (2 or more notes). In Thor, you can have 32 voice polyphony, meaning you can have 32 notes playing simultaneously. In addition, Thor has Release Polyphony and can also have 32 notes sustain after you lift your finger off the key, or after the note’s end in the sequencer (in the case of midi).

There is also the term “Monophony” which refers to the melody line of the song. It is a song which contains only a melody line without an accompanying Harmony. So strictly speaking, if you have two notes played at once, each one octave apart, the song can still be considered “Monophonic.” Confused yet? I’ll let Wikipedia explain this concept of Monophony

A few other notes: 

  • In Reason, as in the real-world, CV relates to Monophonic and Polyphonic voices of a synthesizer. While Monophonic and Stereophonic channels in an audio system are audio-specific. The RPG-8 Arpeggiator and Matrix are termed “Monophonic” which means they can only control one voice of a synth at a time. If you want to create a “faux” Polyphony, you must first duplicate the RPG-8 or Matrix as well as the sound sources they are controlling, and then send the output of both these sound sources to their own audio channels; either mono or stereo, it doesn’t matter. You now have two-voice polyphony.
  • The above points out also that you can have a Monophonic synth that has a Stereophonic “audio” output OR you could have a Polyphonic synth with a Monophonic “audio” output. Plus, you can take a Stereophonic signal and make it Monophonic (panning both channels to center), but if you take a polyphonic CV and make it mono (sending it to a mono synth) you will just drop all the notes beyond the first or last one (just like playing a chord on a mono synth).

Effects Devices in Reason, and Reason’s Routing Suggestions

According to the literature in Reason and Record, there are specific ways in which the Effect devices should be connected. I’m going to plagiarize for a moment and take an excerpt directly from the help file. This excerpt explains the way Monophonic and Stereophonic signals are processed by the effects devices in Reason, and shed light on those little tiny diagrams on the back of the FX devices (come on, give me a show of hands. How many of you knew those diagrams were there to begin with? And how many knew what they meant?).

 So looking at the diagrams, we can see the following connections can be made by the Reason devices: 

RV7000 Digital Reverb: 

Mono In / Stereo Out 

Stereo In / Stereo Out 

Scream 4 Distortion: 

Mono In / Mono Out 

Dual Mono In / Dual Mono Out

Dual Mono In / Dual Mono Out 

RV7 Digital Reverb: 

Mono In / Stereo Out 

Stereo In / Summed Stereo Out 

DDL-1 Digital Delay: 

Mono In / Stereo Out 

Stereo In / Summed Stereo Out 

D-11 Foldback Distortion: 

Mono In / Mono Out 

Dual Mono In / Dual Mono Out 

ECF-42 Envelope Controlled Filter:

UN-16 Unison: 

Mono In / Mono Out 

Dual Mono In / Dual Mono Out 

Mono In / Stereo Out 

COMP-01 Compressor: 

Mono In / Mono Out 

Dual Mono In / Dual Mono Out 

PEQ-2 2-Band Parametric EQ: 

Mono In / Mono Out 

Dual Mono In / Dual Mono Out 

MClass Equilizer: 

Mono In / Mono Out 

Dual Mono In / Dual Mono Out 

MClass Stereo Imager: 

Dual Mono In / Dual Mono Out 

MClass Compressor: 

Mono In / Mono Out 

Dual Mono In / Dual Mono Out 

MClass Maximizer: 

Mono In / Mono Out 

Dual Mono In / Dual Mono Out 

Phew! Now that’s quite a lot of information to take in. However, when you look at it, you can pretty much break it down into a few key points which are easier to remember: 

  • All devices can be connected in Mono In/Mono Out except the MClass Stereo Imager (makes sense right? Because you can’t separate a mono signal or make it wider/narrower. It’s already mono, so you can’t make it more mono. You also can’t magically turn a mono signal into a true stereo signal). So forget using it for anything other than Dual Mono In/Dual Mono Out.
  • Every FX device except the Delay and Reverb devices can be connected in Dual Mono In / Dual Mono Out.
  • The RV7000 device is the ONLY device in Reason which is true stereo (Stereo In / Stereo Out). The RV7 and DDL-1 are the next best thing with a Stereo In / Summed Stereo Out.
  • The Devices that can be used as Mono In / Stereo Out are: RV 7000, RV-7, DDL-1, CF-101, PH-90, and UN-16.
  • Every device can be used as an Insert effect, however not every device should be used as a Send effect. Effects that should not be used as Sends fall under 2 categories: 1. Dynamics Processors (all MClass devices, COMP-01 and PEQ-2), and 2. Distortion Units (the Scream 4, and D-11).

This last point is not really related to the issue of Mono/Stereo, but is an important consideration when connecting devices in your tracks and is another point that shouldn’t be overlooked. 

One other thing I wanted to point out. If you get a chance, you really should check out Hydlide24’s great video on different ways to create Stereo separation in Reason. There’s so much great information in this video, I thought this would be a relevant place for it. He tends to move a little fast through the video, but you can always pause and go over it a few times to follow along. Check out some of his other videos if you get a chance as well. 

Hopefully this information is accurate. I’m human and prone to many mistakes. If there is an error, please help me point it out and make sure it’s accurate. I’ll ensure I get it corrected. And if you have anything to add, I welcome your advice and opinions.
