It would be awesome to have it do what you ask, but unfortunately you can’t put a key tracker inside the doofer.
Either you would have to copy the EQ presets and do it ouside a doofer or make different presets with a doofer and make the key tracker turn them on and off.
maybe I misunderstand, but I recently tried these: https://forum.renoise.com/t/doofers-tuned-devices-bundle/41764
there’s also a tuned eq doofer, maybe you can use this?
