Prosoniq releases NorthPole AU

Prosoniq has updated the free NorthPole filter plug-in to the Apple AudioUnit format for Mac OS X.

This selectable LP/BP filter plug-in brings back the sound of the analogue era to your AudioUnit production environment - still for free. Released as a VST plug-in in 1997 this filter was the first free VST plug-in to be available.

NorthPole is a free effects plug in for AudioUnit compatible applications on the Macintosh. It adds a fully programmable virtual analog synthesizer filter with resonance, envelope follower and an integrated post-filter digital delay to your audio production environment.
