I don’t know if this already exists, so I’m reaching out to see if there’s anybody know of a module like this. Imagine a sequencer that has a display that looks like an EKG (heart monitor). It can have a variable “resolution” at which it runs, and the display scrolls continually. Of course, it would have a “reset” input to start from the beginning. At any time, you can draw on the display to change the values and it’s automatically saved.
My intended use is to control CV inputs of other modules slowly over time.
