route laptop audio through the OASYS to main L-R outs?

[Kevin Nolan]

Hi -

I'll be using the OASYS live for the first time in 2 weeks. For simplicity, I want to route backing tracks (audio only) from a Laptop PPT automated presentation through the OASYS, so I can combined/mix it with live playing on the OASYS; all to its single stereo L-R outs (to the main live mixer).

This is for a single 8 minute segement, constituting a single piece of music.
I intend to use the OASYS on one Combi or one Sequencer setup only, (no interanl OASYS sequecning or karma, just to select one or two live sounds to be played from the keyboard).

So is it possible to have the L-R audio out from my Laptop (with m-audio interface) routed to inputs 1,2 on the OASYS, and in combi or sequencer mode, assign them to the the main OASYS L-R outputs, so I can mix the Laptop audio with live playing on the OASYS?

I realise I'm asking this before trying it. I will get around to it in a day or two but respectfully ask if anyone had done this already and if so what's the best approach?

Thanks,
Kevin.

You can do that with the Oasys and it works in all modes.

The gist is that you can either setup the routing of the audio inputs to the busses in Global mode and that will take effect in all modes, or you can override the Global settings in a given mode and elect to do something specific.

For your purpose it sounds like setting this up in Global mode will work best.

In Global mode if you go to the Basic page and then touch the Audio tab you will find the spot where you need to configure this. In the columns named Input 1 and Input 2 you should set the Bus Select value to L/R for both inputs. Then set the panning of Input 1 to L000 and Input 2 to R127, and adjust the level faders to get the appropriate mix level of the input material versus the level of the Oasys output itself. You might want to Write your Global settings to save yourself having to set this up each time you power up.

If you're going to be working in SEQ mode, for example, you might want to verify that the Global audio routing settings are being used. You can do this by going to the Play/REC page and selecting the Audio In/Sampling tab. In the top left corner ensure that Use Global Setting option is enabled. You can do something similar in Combi and Program modes too.

HTH,

... if you don't want to set this up globally, then in your song or combi, just go to the Audio In/Sampling page, turn off the Use Global Setting option and then set Input 1 and Input 2 so their Bus Select option is L/R and save the song/combi. It's quite cool that you can set up a Global routing that is used by default or override that in each Combi or Song, by just turning off the Use Global Setting and configuring routing for that particular context.

Hi Daz -

That's great - thanks a million. I get what you're saying. The global mode option sounds exactly what I'm after.

Thanks again,
Kevin.

In the past, I've damaged my Triton A/D converters, while monitoring the output of my laptop through the Triton's A/D converters. It probably happened due to some grounding issue, or something like that, so since then I'm very very wary of doing the same to the OASYS.

If you ask me, the safest is to go digital and use the optical S/PDIF inputs from a laptop that supports S/PDIF optical output.

It's true that optical is the safest connection mechanism between any two pieces of gear, since it maintains electrical isolation. That said, it seems extremely unlikely that connecting to the audio inputs on the OASYS would be any different from connecting to the audio inputs on anything else. It's normal procedure.

Hi elvisjohndowson and Dan,

Thanks for the advice. Unfortunately digital is not an option - I'm using an m-audio audiophile-usb and it only has electrical s/pdif, where as the oasys is optical only. So I'll have to go straightforward analogue!

Cheers,
Kevin.
