sending audio out of computer?

Member for

Hi everyone. Sorry if this is an obvious question.. I've just never done this and am getting a bit confused on the best way to do it.

I'm recording with cubase but I mostly use hardware effects and I also sometimes use a 4-track. I basically want to be able to send tracks that I've recorded in cubase out of my computer and into various effects (such as a spring reverb) and back into the computer. Or I want to be able to send tracks out of the computer and into the 4-track recorder.

It seems simple but I don't really get how to do it. I'm currently using a tascam us-122 usb interface. it has an 'insert' slot for left and right channels but don't know if they'll let me use this. I read the interface manuel and it briefly mentions the inserts but I haven't gotten them to do what I want. Do I need a mixer to do this or should I be able to do it with the interface? Thanks for any info, your help is greatly appreciated.

Again I say: disable your internal software monitoring (just as you would if you were using the 'zero latency' monitoring in your audio interface, or an external mixer) and the feedback will go away.

As far as monitoring the results are concerned: the only possible way would be to split the output of the processor in some way so that it feeds your monitors as well as the interface inputs. If the device has both jack and XLR outs you might be able to use both at the same time. Otherwise you would need a small mixer, or possibly some y-split cables.

Yes you can. I've done it with my Mackie Satellite (using just the pod unit, so with only 2 outs available.) I ran the satellite's outs into an external mixer so I could monitor at the same time.

The internal monitoring settings are specific to the DAW software you use (or possibly your interface drivers: if you have zero latency monitoring enabled that will also cause a feedback loop) so I can't tell you specifically how to turn it off. Unless you use Tracktion, in which case select the audio input and disable the "end-to-end" option.

I'm not trying to be argumentative here, so please accept my apologies in advance for my hardheadedness. I just tried this with Tracktion 3. End to End DISABLED. Feedback. Ok. So I muted the channel I would record to. No feedback....until I hit record. What did I miss?

Thats it! Add another sound card to the computer! Then run two different recording software packages. Sound out l/r from one sound card/recording software, get it effected and send it back in the other soundcard/interface/recording software.

You need more outputs to do that properly.

The inserts are no good for audio that you have already recorded into your DAW: these just provide a way to patch hardware between the mic pre-amp and the AD converter while recording.

To use external hardware after recording audio you would need to route the tracks out to your hardware via one or two spare audio outputs, then back into your software via one or two spare audio inputs... as your US-122 appears only to have two outputs this is not really an option.

Or just buy an interface with more than two outputs.

IIRs is right about the inserts and the limitations of the US-122 interface.

However, you could add outboard effects two channels at a time using the two-channel output capability of the US-122. You would have carefully to line up the latencies of re-recorded tracks with respect to the original playing tracks, but that's not too difficult.

I don't see a way of getting four tracks correctly aligned to your four-track recorder, though.

Maybe it's time to think about a new interface with a higher channel count (in and out) if you are likely to be doing this sort of work frequently.

Wouldn't this be creating a feedback loop? You would have to do one track at a time and you'd need to be sure enough with your track to commit.

Thanks for all of your advice! This is really helpful.

I now understand that the inserts are not what I'm looking for, since they're for adding hardware effects AS you record something.

I think sending only 2 tracks of audio out at a time would be fine for now (when I send stuff to the 4-track I'll probably be bouncing it down to 2 tracks anyway), but sadly I can't even get that to work.

All the us-122 has on its front is 2 mic ins, 2 line ins, and 2 inserts. On the back of the interface there are two rca outputs labeled line out L and R, but I assume those are just for monitoring. Does this mean that this interface doesn't have any way of sending audio out or am I missing something?

If it can't send audio out then what kind of replacement interface/mixer would let me do this stuff? I'm fine getting a new piece of equipment if it will let me do this. Thanks again for your help, it's greatly appreciated.

I wouldn't do it. If you're planning to bring these back into the DAW, you're just going to end up doing more cleanup work. What kind of four track are we talking here? Reel to Reel or cassette. If you're talking cassette it'll be pointless. You'd only be adding noise.

If you plan on routing to effects and back into the DAW, you'll need to do it one track at a time and you need to pan everything HARD left and right. otherwise you will be creating a feedback loop. So send out right and return left.

Huh?

Looks like the misunderstanding is in what is played and recorded. The original suggestion was to play two independent tracks through the L and R stereo out, apply effects and then record the wets to two new tracks. No feedback danger with that route.

The big problem with the US-122 is that the outputs are single-ended at -10dBV (domestic standard). This may not be enough to drive the outboard effects units correctly unless they can be switched to take -10dBV inputs.
