Hi – I used whatever came with my phone, which was a Google Pixel 2. I no longer have the phone so can’t verify what version it was, sorry!
I simply found the experience so much simpler and better on iOS that I got a cheap iPhone and use that instead. The main issue I found with Android was the inability to record actual 24-bit files; the recommended app for Android, Field Recorder, dithers to 16bit or at least it did when I was using it. But also the experience of recording on iOS using Apogee Metarecorder was seamless and simpler for me so I switched.
I mostly use the M2D2 going into a Windows laptop. We are currently recording a new album almost entirely with the M2D2 (just a couple of songs with another interface/recorder where we needed more inputs) and the sound quality is really excellent.
Sonosax is having trouble getting parts for their equipment and I believe they just had to raise their prices…I hope you don’t have to wait too long or pay too much for your M2D2!
Thanks a lot for your quick and valuable response!
As soon as I get a M2D2,
I’m planning to test with my Nokia 6.1 (upgraded to Android 10)
and the eXtream driver and SW first; will report back then.
