Topic: ADI-2 Pro FS BE OSX Driver Development?
Having had the ADI-2 ProFS BE for a few days now I’m happy to report that I am delighted with the sound quality and to a large extent it’s features - except perhaps one area. Dedicated drivers to support it in OSX.
I note the manual states that on Windows the ADI uses your Madiface driver for a round trip latency of 2.9ms @ 44.1khz and 32 sample buffer. Excellent and expected performance from RME.
On OSX however no such driver support exists and instead the ADI uses the OSX built in driver. With the ADI in USB multichannel mode my own round trip latency tests at 44.1khz and 32 sample buffer deliver 5.78ms. I knew about the driver support before purchase but I must say this RTL is worse than I expected - particularly given the low latency converters in use.
My thinking is that it would be nice to take advantage of the 6/8 channel operation under usb using both the excellent headphone amps as cue sends for performers and main outputs for control room speakers all while using the ADI as part of an aggregate device but with the current RTL performance this is too big a latency penalty to impose across a whole recording system for that to be possible.
I know the ADI-2 Pro FS BE is a quite newly released device so I ask does RME plan to develop a dedicated driver for it under OSX?
