Echo Indigo IOX Expresscard problem

[sssmith]

I use a Toshiba laptop running Windows 7 Ultimate with an Echo Indigo soundcard and play standalone softsynths live. The card is supposed to play four stereo virtual sources simultaneously, but whichever softsynth I launch will sound, but no other source will sound, even though windows control panel shows the device working properly. I installed the latest driver 8.6 which made no difference. I tried uninstalling, reinstalling- no change. The soundcard lights up when the computer is on. Has anyone else experienced this problem, or has any suggestions? Please help.

Just a couple of additional things: Echoaudio support did not solve my soundcard problem. The manual warns against removing the card while the computer is on, to use the "safely remove hardware" feature, however, many times while transporting my equiptment, the soundcard would pop out when the laptop was on. The manual said possible damage would result, however the unit lights up and performs fine except for multiple use. Is my problem a souncard or Windows problem? Any suggestions would be most welcomed.
Thanks,
Steve Smith

You may have damaged the card or worse the bus in the laptop.
Hopefully not. Try the following.

See the Echo indigo control panel.


Indio dj also has two output jacks, but unlike the original Indigo, Indigo dj provides four independent channels for playback. The jack labeled "PHONES (1-2)" works just like the headphone outputs on the original Indigo. The line out jack, labeled "(3-4) LINE", provides a line-level output that is not affected by the volume knob. You can set the volume for the line out jack via the console.


from the manual

Virtual Outputs:
Most audio cards with a pair of analog outputs will appear to software as having just that, a single pair of outputs. When one application appropriates the card for its use, all other software is "locked-out" from using the card at the same time.

Quite often, musicians find it useful to play back from multiple applications simultaneously. A good example would be playing back digital audio while at the same time using a software synthesizer for MIDI. Another example would be using multi-track editing software. Before multiple tracks can be played back on a stereo device, they must be mixed down within the software to the two output tracks. This takes up extra CPU cycles that might otherwise be dedicated to software effects or some other task.

Your Indigo product gets around this by combining the use of "virtual" outputs with its "multi-client" drivers. Indigo, Indigo io, and Indigo dj appear to software as if they have eight separate outputs. These are mixed together with the on-board DSP to produce the actual or "physical" outputs that connect to external equipment without any CPU intervention. Any virtual output can be sent to any actual output along with any combination of other virtual outputs. The levels and routing of the virtual outputs are fully controllable with the Console, which is described later in this manual.

Bus select (Indigo dj only)
The bus select panel is the area in the middle right of the Console. Each bus
has its own button marked with an A (for analog) and a channel number pair. The button in the "down" position is the currently active bus. Clicking on an
output bus button simply selects the settings that are displayed. In this case
Analog out 3/4 (A 3-4) is the active bus. This means all parameters such as volume, pan, and mute apply to the audio coming out Analog outputs 3 and 4 of Indigo dj. To select an output bus, click on one of the buttons. Alternatively, you can use the function keys F1 and F2.

I hope that helps.
