I just bought the upgrade, and the price was even a little better than expected: $15 rather than 15 EUR.
As noted by 2:43, this is one beautiful UI. Normally, that means nothing to me - just give me a purely functional UI where every control's purpose is immediately obvious. But there's something inviting about D16 UIs. And now I can actually read the damn labels!
First impressions:
- main volume control isn't as touchy as it used to be
- my old user presets didn't make it over
- the previous tiny size UI is still an option if you miss it
- not sure if this is a good thing or not: it sounds much better than the old version
- The early/late level knobs turn into mid/side when "MS Mode" is selected.
Very cool on a Hammond track.
- above, I said "give me controls whose purpose is immediately obvious"...well, this has one that's not: "FX CURVE". The manual says it changes the wet/dry transition, but I'll have to experiment with it to figure out what that actually means (linear vs log?).
