I am tring to use the ASIO drivers for tests of my audio equipments, but can't load the ASIO drivers.

My measurement devices;
ADC : E1DA Cosmos ADC
DAC : Topping D90LE

My Software;
MI Pro +UDP

1. Sound card MME drivers are no problems, always can be loaded well.
2. Manufacure's orignal ASIO drivers(ADC:Comtrue ASIO drive, DAC:Topping ASIO driver) can not be loaded with error message or crashing.
3. general ASIO drivers;
If I select ASIO4ALL driver, the driver can not find my ADC or DAC as the attached pic1,pic2.
And FlexASIO driver refuse to be loaded with error massage, "DAQ device not found!"
How can I load the ASIO4ALL driver or FlexASIO driver?

( I can load ASIO$ALL driver easily in RTA window of REW as the attached pic3)

Thank you for your questions.

1. It is possible to load two different ASIO drivers for ADC and DAC in Multi-Instrument. Here is an example. ADC is miniDSP UMIK-2 mic with its ASIO driver, DAC is RealTek sound card with its ASIO driver. The software is running without any problem (see attached pictures).







2. Generic ASIO such as ASIO4ALL is loaded without any problem (see attached pictures).





With any of the ADC and DAC running in Multi-Instrument, the ASIO control panel can be opened by clicking its icon at the bottom right corner of the screen (see attached picture).

Thank you for your kind explains.

My problems are;
Even if I select and click setting->ADC device-> Sound Card ASIO(Device Model)->ASIO4ALL(Device NO.),
the ASIO4ALL control pannel dose not popup, nor appear it's icon at bottom of right of Win10

But if I select ASO4ALL driver at RTA windows of REW, it's control pannel and icon appear as attached pic1.
All the settings of Win10 and audio devices setups are same between MI Pro and RTA of REW.

In other words, you have to click the Oscilloscope Start/Stop button or the Signal Generator Start/Stop button to run in order to make the ASIO4ALL control panel icon show up at the bottom right corner of the screen.

--> Same results, failed.
Even if I ran the scope/generator, the control pannel or icon of ASIO4ALL did not appear and displays "Not Connected 1" at Channel Configuration
combo box of the DAC driver setup window.

I think that ASIO4ALL driver can not find my DAC.

By default, Multi-Instrument will set the ASIO buffer to Maximum. You can change the default setting via [Setting]>[Display]. Not sure whether this will help in your case or not.

ASIO buffer size : already be selected to MAX.

I know that ASIO4ALL or FlexASIO drivers are not perfect, dependent on the various hardwares,
but I wish that MI Pro would be more flexibility in ASIO driver's troubleshootings.
One of the differences between MI Standard and MI Pro is whether they support ASIO drivers or not, right?

I tested another device, audio interface Motu M2(ADC+DAC all in 1).

I can easily setup ASIO4ALL,can setup the pop-uped control pannel.
But Spectrum Analyzer displays as attached pic1,seems not normal.

Under "Normal" trigger mode, the software will perform software trigger processing which prefers a big ASIO buffer size to be efficient. You can try the following to see if it can solve the problem.

1. Set [Setting]>[Display]>"ASIO Buffer Size" to Max or Auto
2. Change the Trigger Mode from "Normal" to "Auto"

ASIO driver : ASIO4ALL
Triger mode : Auto
ASIO buffer : MAX( and same, AUTO)

results: no effect as attached pic1.
