I just want to clarify for my own sanity, but is there no way of updating the delay time of the delay object with a potentiometer? Seems like such a simple thing but obviously i am misunderstanding how the object works or something. I have searched for info but not really come across anything about it. I tried using a mixer to blend between different delay taps with different delay times but that is pretty unsatisfactory.
Here is what i'm working on, very simple delay/bitcrush/filter effect but pretty useless if i can gain control over the delay time
Thanks for reading
