P565 Siren Filter Set


The P565 Siren Filter Set is a merge for the perfect workflow of highly coveted filters from different hardware audio equipment with a unique signature sound that makes it a Pulsar Modular product.
P565 Siren features high and low pass filters with selectable slope and tunable musical resonance that brings you into the realm of some of the most sought after resonant filters and beyond. It also features two notch/peak filters designed for precise adjustment and creative expression. Each of these filters can be dynamically modulated based on an external input signal or the built-in dual envelope followers with fine control over attack, release, amount and speed characteristics. These features accumulate to a powerful creative use that ranges from subtle movement to funky rhythmic enhancement while still covering phasing, flanging and resonance sweeps.
P565 Siren doesn’t stop there. Use the drive to give body, character and dimension to any sound or warp it into overdrive, taking your sound to where no overdrive has gone before!


  • Transformer based emulation.
  • Continuously variable high and low pass filters featuring 12/24 dB/oct slope with resonance  or a signature 18 dB option.
  • Two continuously variable 20 Hz to 20 kHz band filters that can be configured as reject filters or pass filters (option to switch to King Tubby style step filters).
  • Configurable envelope follower to modulate the filter frequency selections.
  • Drive and overdrive options.
  • Intelligent, vintage or HD oversampling options.

    My new favorite filter. Sounds phenomenal All sorts of uses in my electronic music production, filtering down the aliasing from a dx7, shaping the tone on a breakbeat, filtering a low rumbly moog style sound… i could go on and on.

    The real bonus came when I discovered the drive knob… and then the overdrive! Have not come across any distortion that sounds like this in the box. This thing will blow you away.

    This is a stunning filter. Awesome sound character with extensive modulation possibilities. Love that GUI too!

    I have a handful of soft filters which are on my go to list, and this is now in my top 2. Even though to my ears I prefer the sound of a competitors convolution filter, this comes remarkably close and without the latency, automation and performance challenges/limitations of the convolution option.

    Pulsar Modular are raising the bar massively in the world of plugins. I’ve been using the P42 Climax, Lunar Lander & the P565 Siren Filter Set for quite some time now and they are being used all the time on mix sessions. They sound incredible. The P565 Siren Filter Set is the most recent addition to my toolbox and it’s amazing. Sound shaping is now so much fun. The P565 Siren Filter Set is such a creative tool. Sometimes I literally forget I’m using a plugin as Pulsar Modular products feel so analog both in sound & use. I really can’t recommend them enough.

    WOW! I’m not sure when I last experienced that “wow” effect with plugins or audio equipment in general. Amazing.
