As a MOTU Digital Performer user two things are obvious, I run the Digital Performer DAW and I run it on a Mac. Of course when I was notified by Apple that I could download the Lion update right now, I wanted it right then. The first thing I do? Go to the MOTU web site to see if there are any issues (I learned that from ProTools hell upgrading to Snow Leopard). MOTU being the responsible company that is it had this waiting for me:

Attention Digital Performer users
Digital Performer 7.2.3 is currently not compatible with Mac OS X 10.7 (Lion). We recommend that Digital Performer users wait for an upcoming release of Digital Performer (7.2.4) before they upgrade. We are aware of the issue and working to ship the Digital Performer 7.2.4 software update as soon as possible, free of charge to all registered DP7 owners.

So, I will wait for the update as a responsible Mac/DP user, but I will not wait for other DAW updates unless WaveLab also needs to be updated … hmm, I should probably check that out too! Here’s what they have to say:

Steinberg is happy to announce that the majority of its range of music software and hardware is compatible with Mac OS X 10.7 (Lion).

… and a compatibility list for Steinberg products is available here. Looks like I have to get the update to Cubase 6 if I want to continue running Cubase.
