I've recently decided to get back into recording MIDI tracks and incorporating some drum machines and vintage synths. Over the years, I have mostly used SONAR (and CW ProAudio) as a tape machine as I tend to record full bands ensemble in the live room - that's more my thing as I came from the pre-digital/MIDI world. My last significant MIDI experiences were back when everything was trying to sound like Miami Vice and very machine-like.... but I digress.
I am currently still running Platinum on a Win10x64 PC (but I continue to install the latest version of CW by BL, but I'm just more comfortable in Platinum) . This is a commercial studio so change is slow or avoided when things just work as is. I use RME HDSP 9652 as my interface and am utilizing the 2 MIDI ports to control my 2 (original) Mackie Control surfaces along with a Frontier Tranzport (USB). It's been bullet proof :)
So now I try to add an external MIDI interface (MOTU USB Fastlane or an Arturia USB interface via DrumBrute) and when I attempt to use them, they work but disable my control surfaces. I really need to use the control surfaces... any thoughts or suggestions on where to start trouble shooting? I'm sure they can both co-exist but darned if I know ;)
