Integrating Hardware Instruments and Effects in Ableton Live

Despite the flexibility of software, there's no denying that using hardware instruments and effects is still hugely popular. Rory Dow shows how to get the best of both worlds in Ableton Live.  

Despite the abundance of software effects and instruments, something about the character and tactile interface of a real instrument will always appeal to musicians. Luckily, Ableton Live is more than capable of integrating them. In this article, we'll show you how.

Basic Requirements

The most important requirement for using external hardware effects or instruments within Live is a multiple input/output soundcard. Every signal that needs to get in or out of Live will need its own dedicated inputs or outputs on the soundcard. Let's take a look at a simple but typical setup:

All hardware must be connected to the soundcard before it can be used in Live.

All hardware must be connected to the soundcard before it can be used in Live.

In the example above we have a soundcard with 4 mono inputs and 4 mono outputs, a drum machine, a reverb unit and a pair of monitors are connected. The orange lines represent an audio connection and the arrows indicate the direction of the audio. The green line represents a MIDI connection. The more gear you have, the more inputs and outputs you need on your soundcard. 

Setting Up Live

Assuming correct hardware connections are in place, there are a few things to check in Live itself. Head to the Preferences' Audio tab and ensure that any required input and outputs are enabled by clicking the Input Config or Output Config buttons.

Audio inputs and outputs must be enabled in Audio Preferences.

You can choose to use inputs and outputs as mono or stereo pairs.

Any synths and drum machines that are connected via midi will need the relevant MIDI ports enabled in the Preferences' MIDI tab.

Here we can see two ports enabled. The leftmost ON button enables that port to be used for MIDI output. The middle ON button is used to send MIDI clock signal to that output which is useful for any instruments which can sync to clock, such as drum machines.

Creating Custom Devices

Now that all the relevant audio and MIDI ports are enabled, let's take a look at a couple of simple but extremely useful Live devices which will get any external instruments and effects working within Live. The beauty of these two devices is that when properly setup, they will allow hardware instruments and effects to be dropped into a project in exactly the same way as a native Live device, or VST/AU plugin.

The External Instrument Device

The first of the two devices is the External Instrument Device. Head to the Live Device Browser, open the Instruments folder and drag the External Instrument device to a new MIDI track.

Its job, as you might have guessed, is to handle all the routing of audio and MIDI from a particular external instrument. It's quick and painless to setup:

hi, is it possible that MPV does the same kind of tutorials but with logic and/or some others daws , in case they can use the full potential of a hardware synth ?
thanks a lot
Hi Gaby,

Hope these 2 articles for Logic help:

it only has 2 outputs can i still use this to integrate hardware instuments into live?
sorry...what i meant to post: I have the original Apogee duet, it only has 2 outputs can i still use this to integrate hardware instuments into ableton live?
shuckinfit - Yes you can use your Duet for instruments. Just not for effects (which need additional outputs and I assume you're using the two Duet outputs to connect to your amp/speakers.

Just connect your instrument to either a mono or stereo input and follow the instructions for the External Instrument Device.
is it possible to just monitor with headphones and use the duets 2 outputs for effects?
shuckinfit - I don't think so. I'm not an expert on the Duet, but with most audio interfaces, the headphone output simply mirrors the main outputs.
Shuckinfit -- you can create a aggregate audio device that uses both the onboard soundcard and your Duet, in which case you can use your onboard soundcard as the main out, and your duet for the effects loop.

Here's a video that shows you how to make an aggregate audio device.

Once you've created the aggregate device, just tell Live to use it in the audio preferences.

Hi Rory,

I have the Duet 2 with 4 outputs and replaced my Apogee One with the Duet2 specifically so I would be able to route audio and soft synths from Ableton, etc. through external hardware and pedals to warm them up, have more natural delys, et. al. It seems like this should be possible with the Duet2's 4 outputs, but I have not been able to figure it out after hours of trying, google'ing, and following this article. Please let me know if you have any insight into how I might be able to do this. Am I doing something wrong, or is it not possible?
Thanks and Best,
Hi Michael,

The Duet 2 should be just fine. Connect outs 3 & 4 to your hardware effects and connect the output of the effects to Duet inputs 1 & 2.

Assuming that the Duet is sending and receiving signals ok from the effects unit, the only remaining step should be to setup the Ableton External Effects device as described in this article. Oh, and don't forget to enable all the Duet's inputs and outputs in Live's Audio preferences.

Hope that helps.
