Just posted the following in the Zoom forums...
I'm posting this to help anyone who has gone through the nightmare I had trying to get the Zoom R24 working in Mixcraft Pro Studio 7 on a 64-bit Windows 10 machine. Mixcraft is my DAW of choice, but I also noticed this issue in Reaper and Audacity, so this might fix those issues as well.
Installing the Zoom drivers and connecting the Zoom R24 to my Windows 10 machine worked fine. It became my default audio interface and I could hear all of my Windows sounds through the Zoom.
THE PROBLEM:
With the Zoom in USB audio interface mode, I would launch my DAW and go to device setup. I would select ASIO and select the R24 driver. This is where the issue would appear: No inputs or outputs would show up with the R24 driver selected. They were just blank.
I uninstalled and reinstalled the drivers countless times. I tried Reaper and Audacity with similar results. I tried the 32-bit version of Mixcraft to no avail. The most frustrating part was that there were SOME people that use Mixcraft saying the Zoom worked fine for them, but I was unable to get any of them to walk me through how they set it up (though most would say it just worked).
THE FIX:
Finally, last night, I tried again and actually got it working. Here's how.
- Do not set up the Zoom R24 as your default Windows device (use anything else)
- Do not put the Zoom R24 into USB audio interface mode before launching your DAW
- Launch Mixcraft (or your DAW)
- Once your DAW is loaded, THEN put the Zoom R24 into audio interface mode. Mixcraft will detect the change in the number of audio devices and alert you.
- NOW you can go to devices, ASIO, and select the Zoom R24 driver. Inputs and outputs should be listed!
Following those steps above, I was able to record my Zoom output into Mixcraft, and Mixcraft could see all 8 of the Zoom's channels. I could also use the Zoom as a control surface at this point as well.
THE CAVEATS:
With all of this working, you would think I would be jumping for joy and want to keep my Zoom R24 as a part of my home recording setup. However, there are a couple of big gotchas that make me consider selling the Zoom.
First and foremost, even though it now works, it creates an inherent instability in my system. Mixcraft would crash on exit if I kept the Zoom selected as the device. Switching drivers in Mixcraft away from the Zoom (sometimes I need to record from other sources) would also sometimes crash Mixcraft. If it wouldn't crash, it would sometimes render every audio device on my system as unusable, requiring an entire reboot of my machine.
Secondly, since my fix requires the Zoom to NOT be the default Windows device, I can't use it as my main Windows "mixer" like I do with my current audio interface (a Behringer Q802USB mixer). In other words, the Zoom is relegated to being simply a recording interface and control surface for my DAW, but not the main Windows audio interface. I believe this might be part of the instability issues since I now have two audio interfaces installed on my machine. Having the Zoom as the main Windows interface is problematic because of the method of having to turn on the Zoom AFTER launching my DAW. Whenever the Zoom was connected and used as an audio interface before launching my DAW, I would get zero inputs and outputs, and nothing would work.
CONCLUSION:
Though I love the Zoom R24 in concept, the buggy drivers are problematic enough for me to consider selling it and just keeping my Behringer. I don't really need the standalone multitrack features of the Zoom since I record everything in my DAW, and I already have a Roland A300 controller I can use as a control surface (though it's not quite as elegant as the R24 for controlling Mixcraft, but it does the job and has a keyboard to boot).
If the drivers were updated to allow me to keep the Zoom as my main audio device, connected all the time in audio interface mode, and not have to turn it off, launch my DAW, then turn it back on, I would consider keeping it. But alas, I think the Zoom drivers need a rewrite, at least for 64-bit Windows 10.
Since I was having the same issues in Reaper and Audacity, I do not believe it is the DAW having the main issue, but rather the Zoom drivers themselves.
Anyway, enough of my ramblings. I just hope this post can help anyone having similar issues. And Zoom, if you're listening, please consider having another look at your 2.0 drivers for Windows. I'm not the only one with this issue!
Thank you for listening
