The Key Control Bundle contains a series of Max for Live Devices designed to set parameters of various Plugins to exact MIDI note values. The Bundle covers:

Roar
Auto Filter (Live 12.2 and older versions)
Drum Buss
Erosion
kHs Plugins: 

Filter, Nonlinear Filter, Comb Filter, Ladder Filter, Ring Mod and Resonator

Just place the Key Control device of your choice right in front of one of theses plugins and it automatically pairs with the desired parameter.

Every Plugin has following Features:
-Adjustable Pitchbend Range
-Transpose Functionality
-Smoothing of the Frequency Changes
-Internal Mode for Fixed MIDI to Frequency Values
-Detune Parameter added
-Seperate Options for Linear or Logarithmic Smoothing
-Accepts MPE Pitchbend Information
-Priority Mode for incoming MIDI Information
-Displays Information if Device is linked or not

Additional Information:
Roar Key Control lets you control various parameters, which can be toggled on/off individually, it also lets you control the Feedback Tuning
(This is also possible natively since 12.2, but this doesn't cover smoothing, detune or Pitchbend options, like Roar Key Control does)

kHs Key Control lets you switch between Vst2 or Vst3 Mode (which changes the remote controlled parameter, so make sure you use the correct configuration)

The Key Control Bundle is FREE for Download, so Its accessible for everyone making music with Ableton. Nevertheless quite a lot of work went in to the design of this Devices, so if you wanna support my work and the continuous support for existing plugins, every donation is very much appreciated.
