| UPDATE to this article,
dated 981107. The application AUDIOROUTE, discussed in this article is a great
help for a better understanding of the EWS-routing. This article has been written
some time ago, but lately the author, Morten Egelund Rasmussen, added the following extra
information:
Finally I ran through the source code for AudioRoute. I also checked the graphics.
For those of you who doesn't know what AudioRoute is, I can shortly tell you that it is a
utility I started to write more than 1/2 year
ago, but never finished. Anyway: I'm just a user like the rest of you, so I wanted to make
a control panel that clearly shows how the EWS works.... -- And it really
does :-)
If you want to develop AudioRoute further (or just download the program as is), please
visit the AudioRoute page. You can download the
C++ sources and/or the graphics used in the user-interface. The URL is http://surf.to/audioroute
Please notice, that I am not on the mailing list, so any responses to me

information about the EWS64XL routing should also download the file ewsrouting.zip
from Etienne Brauns in the Documentation paragraph of our Download Page.

How do you send the different audio signals to different speakers? I guess this
question might be relevant to a lot of EWS64-users, so here comes a recipe.
First of all: get a decent picture of how the internal routings of the EWS-synthesizer
work. Take a look in the EWS hardware manual, and get the program AudioRoute
from my homepage.
Note that you can't yet access all controls in AudioRoute.
Get Audioroute...
Here's a short description on what to do (all done in AudioRoute):
- Set the Line-out 1 source selector to the synth.
- Set the synth input selector (the one to the left) to the audio device you prefer.
- Set the *master* volume levels for the 4 different types of signals in the synth part
(the synth is the big red part of the window).
- Set the panning for each of the 4 signal types. That's done with the quadpads below the
volume sliders. You can send the individual 4 signals to wherever you want between your 4
connected speakers (front/back - left/right).
Stop reading now if you don't use the Synth wave devices
- In your wave-file playback program ('Cool Edit Pro' for example), you can set which wave device number (#) you want each
wave track/file to be played in. Set track 1 to "Wave device #1", track 2 to
"Wave device #2", etc...
- You now have two different options:
- Option 1: Send each track through the
effect units (chorus & reverb), but not 4 channel sound.
- Turn on both effect units (chorus & reverb) and set the effect parameters of each.
(You can do that in AudioRoute.)
- Go to Virtual Channels (one of Terratec's windows). Here
you can set the left/right position for each "Wave device" and the amount of
each "Wave device" you want to send through the effect units.
- Now you should get your sound where you want it.
- Option 2: Don't use effect units, but
use 4 channel sound.
- Turn off both effect units.
- Go to "Virtual Channels". Here you can set the left/right - front/back
position for each "Wave device".
- Now you get your sound just where you want it.
Please note all the controls in AudioRoute:
these are master controls. All other controls work lower
in the hierarchy.
To avoid confusion with each wave device (that you set in Virtual Channels), I would
suggest you put the AudioRoute wave volume to maximum and center the wave signal between
the 4 channels. Then make the settings for each "wave device"
in the Virtual Channels window. When that works, you can
always experiment with the master control in AudioRoute.
I hope this explanation is sufficient. To find more detailed information, I'd suggest you
to download the manual to the Virtual
Channels. |
