"The Focusrite could be used with lower latencies than the Presonus, but both could be used without issues using all IOs at the same time, including the SPDIF and ADAT IOs." Pardon, IIRC I only tested using all 18 outputs, resp. 20 outputs at the same time. This works without issues. Focusrite claims that using all IOs should work without issues, too, https://support.focusrite.com/hc/en-gb/articles/208095469-USB-2-0-vs-USB-3-0 . _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
