Hello waedi,

I created this post to help others (including RME's support) out.

Posted first in the correct section related to the USB update (where users are still having problems ), then to this section also as I've seen the issue referenced in different ways here also. Furthermore the driver and update is on the website, so another reason it felt appropriate to add here also.

The USB update has been advertised as a "fix" for the Arc USB sending SysEx data in Logic (particularly). The posts I made are to help those people out, that after running the update, still have the problem.

I've used DAWs and sequencers of all shapes and sizes for decades. Logic, I've used since the early "emagic" days, so I'm fully aware of setting up environments and workflow, etc. it is my first time of owning and using an ARC USB however

If disabling the ARC USB as a midi device within Logic is so "normal" and obvious, then why would RME create a firmware update as a means to resolve the issue, when in fact all they need do is update the user guide to remind users to remove it as a midi device within Logic (or any other DAW that experiences the same thing).

Additionally, what I originally posted is a "work around" because the official solution/fix by RME, is to update the firmware of the ARC USB, which as many of us have noticed, isn't a "fix".   

Not being affiliated with RME (like yourself), it would be misleading and wrong to class a personal solution for a technical issue as a verified "fix".

Stating "The ARC can't spy a computer and change settings in a DAW" is completely irrelevant to what I posted and also indicates you shows signs that you're possibly not so much of a help in forums, rather a hindrance.

Hi Kubrak,
I do agree with you. The thing is, this has been an ongoing problem for people for some time. I've owned this as of now, about 3 days.

After the RME firmware "fix" was not resolving the SysEx issue as it states it should, I removed the device from logic as a midi device, then I posted it as a work around as no one has mentioned this for others (maybe less experienced).

When you're a new or inexperienced user, nothing is "obvious" and issues like this can result in frustration, bad company reputation and unnecessary returns.

Furthermore, if it's such an obvious solution, why would RME create a firmware patch? It's far more simple to update the online guide and product page with an addendum, suggesting that those with this problem do as I've suggested.

So, yes that's why I posted this. If it's "obvious" to you or anyone else, then this information isn't relevant. However, to others it could be the difference between a working setup or a complete nightmare.

The readme also shows that there had been times where Logic missed the MIDI input selection completely. At that time a really screwed up procedure was needed in Logic to ignore the ARC's MIDI - so we changed to SysEx. That helped.
