This is a personal bugbear for the team at SoundSpot during the production process, and we all wished that there was a plugin that could control the cutoff envelope on the group as a whole, so we decided to start work on a plugin that would do just that. Introducing KARA - A bus processor designed to process multiple signals, into one cohesive sound.

As the KARA is an audio processor and receives no midi information, the first task was to find a way to trigger the cutoff envelope in a stable way. We achieved this by creating an RMS trigger that works much like a compressor, so when the signal hits the user definable threshold, which is set using the Sens parameter, the envelope and filter are triggered creating the pluck sound.
