Even though, at the time this article is being written, there are 353 days until Christmas, Prosoniq releases the free North Pole plugin. Slide it down the internet's chimney to your computer for a fully programmable resonant filter, the finest in complimentary stocking stuffers.

You can use this plugin to either create special effects or for emulating analog four-pole synthesizer filter. Even though NorthPole is free, it's still copyrighted. Anyone caught using this program for profit gets put on Santa's naughty list.

• 24dB / Octave (four pole)
• Variable cutoff and resonance
• Lowpass / Bandpass switchable
• Envelope Follower with adjustable sensitivity
• Envelope attack / release times
• Adjustable analog distortion
• Adjustable digital delay after filter with time, mix and feedback
