I’m using Audacity to record mp3 that I send to my guitar player so he can practice to get ready when we meet. The problem is that I can’t register more than two tracks simultaniously using Audacity with my pc under windows 11. The microphone, the piano and the BK-7m backing module are plug in to a mixer Zoom R16 recorder interface controller. So I need 3 tracks to record. My friend is able to do it with his Mac pc. Why not me ? I guest that the drivers used with windows 11 are responsible for that.
Thank you for answering me.
Yes - that is very likely the case: it is up to the Windows drivers. Multi-track devices in Windows frequently use the ASIO protocol which for license reasons is not available in Audacity. You can home brew your own version of Audacity which includes ASIO, but that is not for the faint of heart.
You can check the Zoom website to see if other Windows drivers are available, then report back on what you find. Note that MME and WASAPI may offer a differing number of channels. Check the Device Toolbar 
Fortunately, the R16 has a built-in recorder, so you can simply record on it, then transfer to file to your PC and load it into Audacity. 
Thanks for your answer Jademan. I already check on the Steinberg website for new drivers to use with my Zoom R16 and there is nothing new.
I tried mme in the setting of Audacity but it din’t change anything. Hope that either Windows or Steinberg will develop a new driver that would work out with Audacity. It’s through that I can record on the Zoom R16 and transfer it to Audacity but it would be impossble to ajust each track ounce transfered.

The Zoom would have been my first guess. If you have trouble recording on the computer, stop recording on the computer. I would be surprised if the Zoom didn’t let you individually manage each track. I don’t know if this is intentional, but you seem to suggest the only way to get a show out of the R16 is mixdown.
The R16 provides sixteen tracks for recording and playback (up to eight tracks can be recorded simultaneously) in full fidelity WAV format
That’s from the manual. That seems to suggest you don’t have to mix inside the R16.
Once you import the individual WAV files into Audacity, you can do all kinds of adjusting including time shifting.

You are welcome. When you download the driver, make sure it is from Zoom, not from Steinberg who supplies the incompatible ASIO drivers.
Don’t forget WASAPI.
Zoom claims that “up to eight tracks can be recorded simultaneously”, so you should not be having this problem. koz suggests reading the manual. But in the case of Zoom, these manuals can be notoriously difficult to digest. Perhaps check Youtube instead.
Yes for Windows - but check out the Zoom download before giving up. Note that Steinberg has already written ASIO drivers for Windows that work well - the only problem is that Audacity’s licensing and Steinberg’s licensing conflict. What we need is to get their lawyers to develop compatible licensing.
BTW, check out Cakewalk. I believe it is free and works with ASIO.
Thank Jademan. It’s very kind of you to spend your time giving me tips to settle my problem. I had the Cubase record program coming with the Zoom but it was exporting only wave files that are too heavy to send by email to my friend. That’s why I prefer exporting mp3 files.
By the way, when I checked for new drivers, it was from Zoom, not from Steinberg web site.
I will try some of your solutions.
Thank you very much.
