Hi Eric I tried #1 and for #2 there’s no Chord control application unfortunately
As mentioned earleir I tried the Mojo on an iMac i5 this weekend and had no issues. And I tried an iFi iDSD BL Dac on my Surface Pro 4 and it’s doing up-sampling to DSD256 without any issues (iFi does have a control app and I’ve got the ASIO buffer size on max)
I’ve since sold the Mojo so you can close this support thread but you may want to test the Mojo in house on Windows 10 if you can, because I’ve seen posts on other forums about similar issues with DSD256 and the Mojo on Windows.
