There is no need to uninstall it…
just switch the driver to the interface you are using.
I use a fireface UFX and use the MR816 only for additional inputs and monitoring the amp sounds. I have the extension installed all the time.
By the way the RME has at 256 samples LESS roundtrip latency than the Steinberg at 128 samples. And with Rme I can go down to 64 samples on a busy project, when the Steinberg begins to crackle at 256 samples already. SB needs to do something with their drivers…
I just like to say “Thanks” to SB /Yamaha for maintaining support for the MR816 units!
When I bought mine way back in 2008 (earlier ?) I posted here that I thought Sternberg would have to provide driver support way past the ‘end of sale’ date for hardware if they wanted to be taken seriously in the hardware arena. ( I’d been bitten before… )
They’ve done that as evidenced here.
The interface is still a great box … it’s worked well for me consistently particularly for remote recordings on an older Mac laptop using a Firewire adapter!
