Steinberg Multi-Client ASIO Server with Protools

[ric982]

Hi,
I have a Steinberg UR 824 audio interface and have the
Yamaha Steinberg USB ASIO driver installed.

I downloaded and installed the Steinberg Multi-Client ASIO Server from here
https://www.steinberg.net/forums/viewtopic.php?t=48

This server uses the installed ASIO driver and provides multiple clients for
other software programs that use an ASIO driver. You are supposed to
point this server to the asio driver and then configure any applications to
use the "ASIO Client".

I've rebooted, started the Multi-Client server and set the ASIO driver in this server to
Yamaha Steinberg USB ASIO.

I can start REW and on their preferences page, if I have DRIVERS: ASIO,
I can click the pull down for ASIO DEVICE and see the following selections:
AVID ASIO DRIVER
ASIO CLIENT
AVID Eleven Rack ASIO
Yamaha Steinberg USB ASIO

I selected ASIO CLIENT (for REW) and I can see in the server window
that it has a REW Client that has registered. And if I use their tone
generator, I can hear a tone from the monitors driven by my UR824.

When I start protools (while ASIO MultiServer is running), and select
Setup -> Playback Engine, the Playback Engine Pull down only shows:
Windows Audio Device
Generic Low Latency ASIO Driver

If I select Generic Low Latency ASIO Driver I get
AAE error -6117.

So yes ASIO MultiServer has the Yamaha ASIO driver locked up, but protools
is not giving me the option to select ASIO CLIENT like other applications.
If I close the ASIO MultiServer, then Protools shows the Yamaha ASIO driver as
selectable.

Is there some work around or do you specifically want to prohibit this
multi-client driver head from working with Protools?

Well - I guess I've already found a workaround for what I'm trying. It doesn't really answer the question of whether you want MultiClient ASIO to work with Protools so you may still want to answer that.

What I did do was let Protools use the Yamaha ASIO Driver and I redirected REW to use the Line Out as in:
Drivers: JAVA
Output Device: Line (Steinberg UR824)

This results in REW -> Line Out -> UR824 (DAW Input) -> Monitor Out L/R
I have Monitor Out L/R also direct to pair of UR824 ADATA Outputs that is wrapped to a pair of UR824 ADAT inputs which I can then use as an input to a Protools Audio Track.

I case you're wondering what I'm trying to do it is something like this:

REW Tone Generator ->
Left Track w/ChannelStrip / Right Track w/Channel Strip ->
-> Some AData Outputs -> UR824 HeadPhone Outputs -> Headphones ->
Ears with Hearing Problems +/- Hearing Aids
(and that is working now).
