How to set a button to change slider to specific value

I have a slider that controls an echo/delay time as wired to the audio mixer's effects (via exposed parameters - the parameter is called "delayTime." This is a musical app and so there is a tempo (BPM) and I have created buttons that automatically set to Tempo-Based Delays of 1/4 note, 1/8 note, and so forth.

What I need is for this button to also change the slider to be at that value. For instance, if by pressing the 1/4 Note delay button, the delay time changes to 600 ms, the Delay Time Slider should adjust accordingly. In my current setup, it does not.

In order to access the Audio Mixer ("masterMixer") I've tried using something called the masterMixer.GetFloat function, but not sure how to use it. Does anyone with Unity audio experience or relevant UI knowledge know how I could change this script?

Thank you!!
