I'm running Ableton Live 9.5 in Windows 10 and the current version of Ultrachannel. My problem is that the fonts currently look like this for the parameters.

Can you tell me if there's a known fix for this? 

We've seen that problem pop up in the past when someone has the same font installed multiple times.  Designers in particular may have multiple copies of the same font installed for whatever reason.  My colleagues, Dan or Tom, may chime in with more information, but as far as I can tell, UltraChannel is just using the default system font for those fields, which one Windows 10 should be Arial or Segoe UI.  Could you check if you have either of those installed multiple times?  On Mac there's an app for this called Font Book;  I'm not sure what the Windows equivalent is.
