You'll have dig very deep into modules to fix it - way, way inside the green knobs, the MouseDrag accumulator primitives are set to hide the cursor - just delete the boolean 'True' connected to the 'Curs' input.
If you're very lucky you might be able to right click one of the green knobs and select 'synchronise all', so that you only have to edt one of them - depends whether the knob modules are still identical.
Feel free to use any schematics and algorithms I post on the forum in your own designs - a credit is appreciated (but not a requirement).
Don't stagnate, mutate to create. Without randomness and serendipity the earth would be just another barren rock.
