Can be done, but requires a trigger-sized pulse on input. Portamento (aka slew rate controller aka glide). - Knob version fairly simple. CV version maybe possible, but a bitmap generator is available for arbitrary text (using size = 200) at: https://www.myfonts.com/collections/quentin-font-urw?tab=individualStyles ...
