A couple weeks back we explored the basics of audio effects on our blog in an effort to help our readers who are just getting into the world of music production. Audio effects can add depth and dimension to your sounds and they are really one of the essential building blocks of electronic music. This week we will explore some options for expanding your sonic palette with external hardware effects routed through the aux send and return channels in Ableton Live. Most music production software such as Logic, Reason and Ableton Live come with built-in audio effects which can sound fantastic. But a problem you may run into is that tracks coming out of these programs can end up sounding very similar. This is advice that Moby offered in a recent interview that we did with him:
Today it’s all software based so it’s much more accessible. But the danger is that it all sort of sounds the same.. It’s very easy to stay purely in the digital realm because it does everything. – Moby
Using Hardware Effects for a Unique Sound
One of the easiest ways to incorporate an outside element into your Ableton Live workflow is to route sounds out of Ableton and into a hardware effects processor, then back into Ableton Live. If you happened to catch DJ Kiva’s APC40 dub performance in May, he used this technique extensively to create his dubbed out sound. In the video above you’ll find Kiva using a Korg Kaoss pad that has been routed out of Ableton and back in again to create effects that you can’t find inside the program alone. After seeing this video I asked Kiva to go over the basics of how to set this up. It wound up being easier than I thought it would be and it’s brought a lot of new ideas to my workflow.
Routing External Hardware Effects into Ableton Live
Below is DJ Kiva’s setup for routing external effects into ableton Live. I’ve replaced his Kaoss pad with a Roland SP-404 sampler, which offers audio-through and effects processing on that audio. You may find that hardware gear that you own such as Korg Electribes, Monotrons, synthesizers or drum machines can process audio. Guitar or bass pedals can also create unique sounds that can help create your sonic identity.
Make Sure You Have Two Sets of Outputs from your Audio Interface
You can use any sort of effects processor for the following setup as long as you have an audio interface that can handle the inputs and outputs. To make this work you’ll need an audio interface with at least two outputs and one input. They can be mono (and your effects will also be mono) but optimally you’ll want two stereo outs and at least one stereo input. One output is your master sound output and the second output will be routed to the effects device. The input will be used for the effected signal. In the following example I’m using a Native Instruments Komplete Audio 6 (channels 3 and 4 for input and output) that is connected to the Sp-404′s ins and outs. The master output is set to 1/2 volume.
1. Go to your preferences and go to the audio tab. make sure you have your interface selected as the input & output device..
2. Under input & output tabs, activate the additional ins & outs you will use.
3. Open Ableton’s i/o tab by the master track.
4. Select the “Return A” track.
5. Under the “Audio To” tab, select “Ext out” and then output pair 3/4.
6. create a new audio track in session view and set i/o to Ext. 3/4 and monitor mode to IN.
7. Connect a set of cables output 3/4 on your interface to the inputs on your effects device. In this case we have connected to the inputs on our SP-404.
8. Connect a set of cables from outputs of your effects device to inputs 3/4 on your audio interface.
9. Enable your effects processor..
10. Now back in your Ableton session view you’ll find Send levels for channels A and B above the volume faders on each track. Try playing a loop of some kind on audio track 1 and turn up the Send A knob to route effects to your hardware processor..
11. Make sure that the level on your audio track (“Aux Signal” in the examples) is turned up when you hit send A knob on any music channel, it will now send signal to your device and come back into the session. You can now easily record the incoming signal and have it on a separate track in your session.
12. One thing to note about this setup: there can often be a small delay when routing these sorts of effects. When I asked Kiva about this he mentioned that this can sometimes add to the character of a reverb or delay. If you want to fix this timing offset you can adjust the start point of the sample in Ableton.

An Overview of Audio Effects
This week we’re taking a step back to the basics in order to give our beginner readers an overview on audio effects and how they work. If you’re just starting out on your audio production journey, you’ve most likely come across effects in your gear or software. These might be delay, reverb, distortion, compression, phase, flange, pitch-shift, ring modulators or filters. This article aims to get you familiar with these terms and what these devices do. In future installments of this series we will get a bit deeper on specific types of effects (as some subjects such as reverb require an article of their own.) For now we begin at the beginning…
What are Audio Effects?
Audio effects are devices (analog or digital) that are used to intentionally alter how a musical instrument or other audio source sounds. Effects can be subtle or extreme and they can be used in live or recording situations. A good example of audio effects are the “stomp-boxes” that many electric guitarists use to realize their desired sound. By chaining together many different types of effects units a musician can sculpt a unique tone. Almost all popular music benefits from creative use of effects, the only exception being an all-acoustic show (and even then there are usually effects involved). All commercial music is enhanced with effects and electronic music makes liberal use of these devices. With proper use they can really enhance your sound and take the listener to new sonic spaces.
A Brief History of Audio Effects
Modern day effects are all a result of the evolution of technology and the advent of recorded sound. Around the Mid 1940’s recording engineers started to use reel to reel tape machines to create delays, echos and sound effects. In addition to tape, microphone placement and movement were found to create sounds that had not previously been recorded. In 1948 Harry DeArmond, creator of the first guitar pickup, created the first stand-alone effects processor called the Trem-Trol by running the electric current of the signal through liquid to create a tremolo sound. This device was used by Bo Diddley and led to more development in the guitar industry of the 1940’s and 50’s where guitar amplifiers started to introduce vibrato and reverb effects. Reverb was initially created by driving an electrical signal into a metal plate or spring to create multiple echos or reflections of a sound.
Back in the studio, recording engineers started to use echo chambers to create echo effects or a unique tone to their recordings. Echo chambers were usually long, low rectangular spaces made from sound-reflective materials such as concrete. They were fitted with a loudspeaker at one end and a microphone at the other to create an echo effect that was used on many recordings to enhance vocals. As they were often custom-made, these echo chambers became the sound signature of a given studio at that time. As technology developed, many reverb devices allowed for electronic re-creation of the echo chamber effect. Equalizers and compressors arrived in the studio in the 1950’s and 60’s with the Pultec equalizer which defined the sound of many recordings of that era.
Hardware and Software Effects
Today audio effects devices come in both physical and digital form. Audio signals in electrical format are processed with physical (analog) hardware whereas audio signals in binary format (digital) are processed mathematically by software. Both methods can achieve similar results. In the physical world, effects are usually rack-mounted devices that have cables running to and from a mixing board or they can be something like guitar effect pedals which receive signal from the instrument and alter the signal as it flows to a mixer. On the digital side you can find effects in most music recording software packages. DAWs such as Ableton, Logic, Cubase and ProTools all come with audio effects built-in. Other software packages likeReason, Maschine, Traktor, Audacity, Peak, and Soundforge also come with audio effects. Audio effects are often simple devices that do one specific thing to a sound, although multi-effects processors are also popular for those who want many different effects in one package. It is also worth noting that many instruments (especially synthesizers) come with effects built-in to the machine. (read more)
