On multiple occasions, I’ve attached a key tracker to a filter’s resonant frequency, and had to caaaaarefully tweak the min/max to get the tuning right. It would be great if, when the key tracker were attached to something in kHz, it would give you the option to lock the note frequency to the output. A button to automatically set the min/max from the key range would do the trick. (Yes, I’m writing a script to do that… but why should I have all the fun?)
No matter what you do with the min/max you wont get a completely correct result with that, search for ‘tuned devices’ on the forum, this has been done with several implementations.
