Polish plug-in makers PSP are touting their new StompFilter plug-in as being very creative. They say it offers super-wide variety in its sound and modulation possibilities. The testimonials suggest that even tiny variations in settings can be very inspirational. How much can you do with a filter? Loads, apparently.



I’m not sure what the “stomp” element is about other than it shares the same stylings as their StompDelay plug-in. But suffice to say that the controls are nicely laid out in a vaguely stomp box-like fashion. The top section gives equal billing to the filter and LFO, which shows the importance PSP are putting on the modulation. It also sports a multi-function LED display. There’s a lot going on in the LFO section but probably the most interesting knob is the LFO Randomiser. This introduces what they are calling “natural variations” onto the modulation, from the rare and subtle to the manic and chaotic.

On the filter side, the stand-out feature is the frequency slider. While you can always use the knob, StompFilter gives you an alternative and more accurate way to address the cut-off. The slider can display different scales and frequency ranges, including note pitches, helping you make the most intentional use of it.

The bottom half of the plug-in houses the envelope and relational controls on how everything connects together. There’s a Freeze section which halts the modulation at the current position while maintaining the filtering effect. And finally, you’ve got some limiting and soft compression.


It’s the modulation capabilities that really shine from StompFilter. It’s able to add movement and dynamics to anything you run through it. The way you can make subtle changes to produce big results and take control of exactly what you want to happen is a lot of fun.

StompFilter is available now for pretty much all platforms and formats for $49 until the end of the month when it goes back up to $69. More information and a 14 day demo available on the PSP website.
