Fuzzpilz has updated Oatmeal to v37-6b.

Changes:

• Fixed a bug involving all-notes-off messages that was causing some trouble for Sonar users.
• Some more filter changes: You can now use the two filters in series as well as in parallel, and you can set the second filter's type separately. The default behaviour for that is to just use the same type as the first filter, so old patches will work just the same without adjustment.
  
  NOTE: Old skins will be missing the third switch state for the filter doubling switch (it'll work, but they'll just display the "on" frame for both parallel and serial modes), and of course won't have the second filter type switch at all.
