I've been using Guitar Rig 4 for a year or two, and it's a fairly useful toy for a bedroom guitarist. Currently, I use a Behringer UCG102 USB interface, which has a guitar in and headphone out.

When connected to my computer, it works fine, I get the modified audio via the headphone out. However, if I want to listen to practice materials, media on my laptop for example, and play along, I have to jump through a few more hoops; my current setup is to use a 1/4" lead from the headphone out to my amp, use a 3.5mm cable from the headphone port on the laptop to the same port on my amp, and then plug headphones in my amp. This way I can get both my guitar audio and computer audio at the same time. It's convoluted, but provided I have an amp, it works.

However, I'm away from home at the moment and don't have access to my amplifier, though I have a guitar and USB interface along with GR software. I can't seem to configure the ASIO4ALL drivers in such a fashion that I get the normal laptop output via the USB interface, without cutting off the output from Guitar Rig. Can anyone advise me on a way to have the two working simultaneously?

You should be able to hear both your computer and GR through one output. Are you sure your audio interface is set as both the output and input device in both GR (or a DAW if you are not using GR as stand-alone) and Windows? If that's the case, there might be a problem with your drivers, you might need to update them. – Archundia Jun 23 '14 at 23:07
Also, yours seem to be a common issue with ASIO4ALL drivers. It might be the case that in some system combinations (or maybe always?) you just can't hear more than one sound source. See… and and – Archundia Jun 23 '14 at 23:09
Nevermind I think I found the issue, posted an answer. – Archundia Jun 23 '14 at 23:25

I think I know where is the issue. My Windows-fu is rusty, but here is what I found.

Solution, in short

Get ASIO multi-client from here or here (they are different, you might want to try both). After installation you should be able to use your interface with more than one program.

What is happening?

Seems that ASIO in general (including ASIO4ALL) can't handle more than one program using one same output.

Support for using ASIO with multiple programs at once. Previously, if you were using an ASIO driver (so that you have low latency), you could only use ASIO with one program at a time. Now you can use multiple programs at once with ASIO - for example RealBand and Band-in-a-Box at the same time.

Steinberg solved this by creating an ASIO multi-client server that you need to download and install. Seems that this is exactly what you need, and seems to work with all ASIO capable interfaces.

More info:

There are other ASIO multi-client drivers you can try, like this one:

From the above, we discover that:

ASIO (Audio Streaming Input Output) is a technology of Steinberg. It allows for low latencies and pretty much every state-of-the-art audio device is nowadays delivered with an ASIO driver (on Windows, at least). However, the basic idea behind ASIO is that professional audio applications entirely take ownership of the ASIO device. Only very few ASIO drivers support true multiple application access. This effectively means that you can not use 2 or more applications using the same ASIO device at the same time.

In other words, you'll need Steinberg's or Vidance's ASIO multi-client driver to route more than one program to the same audio interface.

Another alternative is to use JACK

I found some people were using JACK to solve this issue. It's an internal routing system for audio and MIDI. If it's anything like Soundflower, I believe they might be routing everything to JACK, and then routing JACK to the audio interface, using JACK like a mixer.

+1 for mentioning JACK. Every OS should come with JACK installed by default. :-) – Lee White Jul 6 '14 at 12:03
I remember to have tried Vidance's and Steinberg's ASIO multi-client driver in the past, but did not achieve to do this (have you been successful with this @JCPedroza?) : Run DAW (for example Ableton) with ASIO4ALL and have Firefox playing a Youtube video at the same time. Is this possible with one of these ASIO multiclient driver ? [Here it is ASIO + WDM at the same time rather than ASIO + ASIO at the same time, because Firefox doesn't use ASIO] – Basj Feb 14 '15 at 20:56
any JACK tutorial for using VST and Windows Sounds? – Richard Apr 18 '15 at 19:09

I found this here and it lets you listen to windows audio as well and send audio over the network.

The answer depends a good deal on your operating system and precise setup, but you should be able to do this purely via software.

  • Try routing Guitar Rig's sounds into a DAW, and then listen to your DAW's output via your laptop speakers/headphone jack. This way you will have a software mixer, and be able to hear your effects laden sounds.

  • Try switching your core audio drivers over to the guitar rig, so that all audio is sent through it.

For what you are trying to do, you might have a lot more fun if you switch to a more fully featured sound card, such as those provided by M-Audio, or presonus. They make doing this kind of thing very easy.


You can get literally thouands of guitar effects for free via the VST plugin system.

Welcome to Music.SE @baordog! Great answers already… BTW, I couldn't use the link to your webpage on your profile - are you also at ? If so, this page works fine... – Bob Broadley Jun 23 '14 at 22:42
Yes, that's me! – baordog Jun 23 '14 at 22:45
"The answer depends a good deal on your operating system and precise setup" He mentioned ASIO4ALL, so I'm assuming he is running Windows. – Archundia Jun 23 '14 at 22:55
"Try switching your core audio drivers over to the guitar rig, so that all audio is sent through it." Core audio is for Mac. The asker is running ASIO4ALL. – Archundia Jun 23 '14 at 22:59

There's a recorder and a player in guitar rig I use it all the time. You drag a track and drop it over the player and you can play it and slow it down and change the pitch. Its a pretty useful tool helps with practicing. You can't play another media application on your PC if you have asio as in the first answer

I also bought a Beheringer Guitar Link as an input device for my laptop and am frustrated with it. The ONLY solution that I have found that works perfectly is my Line 6 Guitar Port, which I have connected to my desktop. The problem is that the AISO driver takes over and de-activates your sound card drivers. That means that only AISO programs work and not things like Firefox or Chrome. Using a proxy AISO program allows you to use multiple ASIO programs but not programs that use your sound card drivers simultaneously. Guitar Port works differently. It becomes your sound card and allows all programs to access it equally. I use it all of the time with Youtube, my audio collection, etc. I guess I'll be buying a second Guitar Port.
