WOK updates FlexFilterbank2 to v2.1

WOK has updated FlexFilterbank2 to version 2.1.

New in this version:

• The output of the 8 filters can be controlled by incoming MIDI notes to "play" the filters with a keyboard.
• The middle octave's notes C - C' trigger the envelopes for the output volume of the 8 filters (with fixed or variable velocity).
