For anyone that was curious about the Bb3 to B3 thing I was talking about earlier in this thread regarding the OTS Famous E, here's what OTS had to say about it. He's right about that Al Jarreau song as heard below.
As for the hiss issue, he says that's been fixed, and of course that has also already been reported by both Virtuoso (the guy who initially reported it) and Greg from OTS, as I mentioned previously.
"The Bb3/B3 transitions to different hammers, which is why you hear that change when it gets to the "bell range". You can hear this in the first few notes of the intro in the Al Jarreau song, "Not Like This", for example, when the Rhodes hits the C above middle C. That being said, if you prefer a smoother range instead, you can turn off the bell range in the advanced section of the interface. I know that was Jay Graydon's preference, which is why all his presets have the bell range disabled."
Here's the link where this was initially reported, with audio example https://vi-control.net/community/threads/orange-tree-model-e-rhodes.94529/post-4596993
