WOK has released FlexFilterbank2, a filterbank VST effect plug-in for Windows with 8 adjustable band-pass filters.
From subtle changes to strong vocoder-like effects, FlexFilterbank2 can be used in any style of music. Its analog sound character can also become dirty when overdriving the input stage.
FlexFilterbank2 is free, with a nag-screen and 1 preset only. An unlimited version costs €10.
