Looking for a particular Plugin

Hi,

I’m looking for a particular plugin that works in Ardour. for the last 12 years i have been using Cubase for production work, there was a plugin in cubase called ‘Step Filter’ which allowed you to create step sequenced filter effects, anybody that has used Cubase should know what plugin i’m talking about as it’s been in almost every version for the past 7 to 8 years at least. Has anybody come across anything similar for Linux that can work in Ardour?

thanks
