Guitar Amp USB Out Shows up in CW as MIDI

Recommended Posts

I have a Marshall CODE 50 amp and I'm trying to use its USB out to record audio in CW (I just installed the latest version of CW btw). The CODE comes with no drivers and there are none available from Marshall. Marshall claims that its CODE amps are fully USB compliant, so they need no drivers. I have gotten this amp to work in Band in a Box just fine. It found the CODE and recognized it as an audio device. But in CW it shows up only under the MIDI inputs and outputs, which obviously doesn't do a bit of good. I guess I'm wondering, is there a workaround for this, or must I use my audio interface and forget about the amp's USB out?

I almost always use ASIO. Which other one would you recommend? I guess I can just start with WASAPI Exclusive and go down the list. I don't know what WDM/KS is used for.

For a device to use ASIO driver mode, it must have an ASIO driver or a wrapper like ASIO4All which presents WDM drivers to the host as ASIO.

The manufacturer has chosen not to supply an ASIO driver so ASIO mode is not an option. You really don't want to add ASIO4All if you have another device with an ASIO driver as this can cause problems.

Sounds like a plan. Pick the one that works best for the device/project.

I don't like ASIO4All, I've had problems with it taking over my system and not wanting to let go.

This is why I said it was not an option in this case. Even though it is not a true ASIO driver, it looks like one to programs that work with ASIO like DAWs and this is a problem if there are devices with true ASIO drivers. There should only be one ASIO driver installed for any device.

The point worth mentioning is that you cannot use 2 ASIO audio interfaces at the same time. If you have an  interface that uses ASIO then that's the device your going to be using with Cakewalk. The Marshall is using what are called  audio codex generic drivers. They will work fine buy themselves if your not using your audio interface.  This is a common fault with Amps that have USB ports. They are next to pointless in a system that already has a interface. Best to use the audio output run to your interface or better yet, a mike.

Thanks for the additional info, guys. Well, for starters, I did try WASAPI but it was giving me problems. The piece of music I'm working on right now is fairly large and, even though all tracks are MIDI, there are 22 of them, although only 10 and 12 instruments are playing at any one time, respectively. Nonetheless, at least about half the time, roughly halfway through the piece, it would fall into a state of total distortion. If I paused and restarted it, the distortion would clear up and usually go away for the remainder of the piece, but this was unacceptable to me, so I went back with ASIO. And yes, my interface has ASIO-specific drivers that have always worked very well.

I've been running the amp's audio out into the interface. I prefer this method over a microphone because of the ambient noise level I have to deal with here. Some CPU fan noise and also a cockateel in the background who likes to chirp at unpredictable times. And occasionally the dog decides to bark. The downside to running straight from the amp to the interface is I'm picking up some line hum now. Nothing very serious, but it's there, raising the audio floor. I can probably nail the hum with a parametric EQ -- haven't tried yet.

Next time I'm working on a smaller piece, I'm gonna give WASAPI a try and see if CW will recognize the amp as audio. I never did try and see if that would work, since I was running into problems with that driver mode.

Yes my line out from my Blackstar is unusable for the same reason. That's why I use a mike.

A solution to using a mike when you don't want leakage or disturb the household is to make a little isolation room for the amp. This can be a closet or even a insulated box. 

As a addition to this problem when I tried the USB output of the amp using WDM mode it had the same hum.  

Guitar amps are noisy buggers at best. You just need to play loud and drown it out!

Heard that! That's usually been my approach.
