Anyone have info on making a circuit to ramp between two rate pots?

[Nitefly182]

Im building a neovibe and would like to have the option of ramping between two rates without an expression pedal taking up a bunch of extra board space. Is there a basic ramping circuit anywhere out there?

This is a Korg Integrator, slews control voltages.



Not sure if its what you need???

Look for LERA.

That looks like what I want since it works back and forth between a max speed and the standard rate pot but it says it wont work for a dual speed pot like the one in the neovibe

Use a VTL5C3/2, which is an LED/LDR module with a center tap. It happens to do exactly what the Neovibe needs, just not what all dual pots need.
