 desc:Saike 4-pole BandSplitter
 tags: bandsplitter
-version: 0.20
+version: 0.21
 author: Joep Vanlier
-changelog: Properly initialize first order phase matchers when preparing the FIR for 2p FIR mode (this lead to a volume increase when done incorrectly).
+changelog: Add option to use absolute upper and lower limit for the frequency range (new default!)
