Appendix E: Multi-client audio FAQ

Q: What is “Multi-client audio”?

Multi-client audio is a feature that lets you use different inputs and outputs

on your Echo card with different applications at the same time. This way,

you can use several different audio applications with just one Echo card.

Otherwise, you would have to use a different soundcard for each audio

application.

For example, suppose you own both Cubase VST (multitrack audio) and

Reality (software synthesizer). You can now set Cubase VST to play out

through Mona outputs 1 through 4, and set Reality to play out through

Mona outputs 5 and 6. In previous Echo card drivers, you had to choose

between one software program and the other.

Note that all of the various interfaces are multi-client. You could have an

ASIO application, a wave application, and a DirectSound application all

running at the same time. It's very flexible.

If you want to use multi-client audio, you need to enable it in the main

driver properties page. See the section entitled “Additional Configuration

Settings” in this manual.

Multi-client audio can be difficult to use, depending on what combination of

software applications you are using.

Q: So what's the catch?

The catch is this: all the apps using the Echo card at the same time must be

set at the same sample rate. This is a limitation of the hardware.

Say that you didn't follow this rule in the previous example. Say that you

initially had Cubase VST and Reality set up for 44.1 kHz- so far, so good.

Then you load a song into Cubase that is set up for 48 kHz. Cubase will

change the sample rate of the hardware. Unfortunately, this means that
