I have been asking for this since I got the Kemper. It sure helped when they changed it to read Eb instead of D#. For me I ALWAYS play in Eb. What I wanted (and would still like to have) was basically what my Digitech 1101 did. It let you globally tune the whole unit in half steps, so when you hit your E string, (which was actually a Eb note) the tuner read E. A string read A etc. (It had cent adjustment too in between that) It helped a lot when using the harmonizer too so I didn't have to figure the offset in when making custom scales or what key to use. If If I was harmonizing to what we all know as an E major chord, I didn't have to figure the scale around D# But E. I loved that. I was real surprised global offset tuning wasn't offered with the kemper, but I've worked around it with other devices before I had the 1101. Not a deal breaker by any means, just something I guessed would be pretty easy to offer. A few of us went round and round about this before they changed the b/# thing.
Yeah should be relatively easy to have custom tunes etc
