The distortion issue is resolved. The critical setting was "Allow Pull Mode," which shouldn't have been needed, but it works. Even after setting that, I had to set the buffers pretty high (1024), which surprised me. Resampling always came on by default, so I turned that off. Weirdly, the...

John: Thanks for that, and apologies for not publishing my results from last nights' testing. FlexASIO measures without distortion but is limited to a single mic. I have the upgrade, 4 UMIK-2 mics and a USB3 hub I'd like to engage. Is there a way to use FlexASIO with 4 USB mics? I think I'm...

John: After uninstall / re-install of REW and ASIO4All, Java drives work fine proving the signal path. ASIO4All fails in every configuration I've tried (I'll email or upload the full test results if that'll help). This might be a hint though: Note that ASIO4All is reporting to you 44.1/24...

:reading: I probably won't get deep tonight; still chasing distorted sweeps using ASIO4All. Sigh.

Don't wait on me; I reinstalled both REW and ASIO4All for a different reason. I didn't save the original log, and the error hasn't come up today; I'll post if I run across it again.

John: Intuitively, that makes complete sense to me. The only interaction that I can imagine from what I've seen is that the ASIO4All control panel shows that the mics are sampling at the same rate as the output path (HDMI) when I set it explicitly at 48 KHz (I had it running clean one time at...

I'll post later today... just waking up. :snoring: Would yesterday's stacktrace have been recorded in a log that I can find, or is it only available to the user at the time it occurs in the GUI?

Send me a reference to the API, and I'll take a look to see if I can offer any help.

John: After further testing, I've characterized the behavior of ASIO4ALL and REW with respect to USB microphones. I wrote that up as a feature request and posted it in another thread on this forum. I did that, because I saw that others had begun to request features this way; let me know if...

This is limited to Windows installations using more than 2 microphones, but for those following the guidance of experts like Anthone Grimani, we need 4 microphones. By default, it seems, ASIO4ALL orders devices in the order the WDM interface returns them to ASIO4ALL when it asks for the list...

I don't know if this is related, but I have recently uninstalled and re-installed ASIO4All multiple times trying to chase down an issue with USB Microphone ordering (John knows about this one, too). The first time starting REW after uninstall / reinstall of ASIO4All, REW reports that it's...

John: There are 2 parts to the process to identify the microphone order in REW, and the order does not track with either the port order on the hub or the order in which the microphones are plugged into Windows in that session. The first step is to determine the Location information, which...

John: UMIK-2, yup. That was a typo. I've deleted all the UMIK microphone devices in the device manager and am currently poking around the registry making sure I've cleaned up everything or identified all the detritus before starting to add things back one by one. If I'm successful, I'll be...

I'll start simple and add detail as needed throughout the thread if we get there. I'm hoping I'm being dense, and there's some easy mapping I'm missing, but I can't for the life of me figure out how to identify which mic is which when plugged into one of 4 ports on the USB hub. I have the...
