Making sure the 18i20 is fired up (before the application you are using it in is launched) seems to also be something I've noticed, so the driver can 'get control'.
I like how it works when it works, but lately I've noticed some weirdness like the info above with it.


Thank you, Bob. Yes, the first thing I thought of was mismatched sample rates because you are exactly right about finicky. I think I'm good. My whole computer system is usually on so I'm pretty sure there is no 'warm up' type requirement, but I'll experiment.

I run everything in the room at 44.1, 16 bit. Are you possibly suggesting the Focusrite might be more stable at 24-bit?

If it helps, here is the equipment involved, pretty much in order of the signal path:

i7 home-built PC (no difference when turned off), latest drivers
Behringer X-Touch MIDI controller (no difference when turned off)
iRig Keys 37 MIDI keyboard
Roland Integra-7 hardware MIDI synth
Focusrite 18i20 2nd Generation with latest driver
TC Electronic Finalizer Express
Presonus Central Station with remote
Adam A5X monitors plus Adam subwoofer
