digitally timed alternative to ep2

[feNix_Official]

hi all, im trying out a new project that i need some help with.

first of all, im trying to create a cutoff filter sweep on bass guitar.

i need an alternative to the ep2 expression pedal, i need something like a control voltage that can be timed - for instance say i wanted the voltage to go from 0% to 100% in the time span of 30 seconds or even 48 seconds (which could be set digitally somehow) to create a full spectrum cutoff filter sweep. i would like an alternative like this so i wouldnt have to multitask, which would cause a more uneven sweep than the gradual sweep that i could achieve from another timed cv. but how can i do this?

thanks

btw, it is heard very often in edm.

There are probably many solutions, but the first that comes to mind is the (unfortunately dis-continued) Multi-Pedal.

I wonder if Silent Way might be workable for this.
