Just finished a new Max for Live device for Ableton Live 9. Introducing the Morph Filter!
It allows you to morph between 5 separate audio filters, each of which can have its own filter type, cutoff frequency, gain and resonance.
It's kind of like the filter in Ableton's Sampler instrument, but it has a few extra options and you can drop it on any track you like!
I'm planning to release it somewhere soon as I get a website sorted.
