<div dir="ltr">Hi Folks!<div><br></div><div>I'm needing help understanding what the code for the frequency down below in bold text is doing. </div><div><br></div><div>Context: I'm trying to build a code that will randomly pick frequencies and rhythms within a given range. As time passes my goal is to write a code that will also allow the frequencies and rhythms to change. I know I'm not ready to understand how to code this yet as I am teaching myself at my own pace. But I would like some help if maybe someone could talk me through what the frequency portion of this code is doing. I took the frame of most of my code from a ChucK example and am changing it for a composition of mine.</div><div><br></div><div>I don't understand the relationship between the scale part and the freuency part.</div><div><br></div><div>I don't understand the Math.pow.</div><div><br></div><div>I do understand math.random2, int, and freq.</div><div><br></div><div>Thank you much!!</div><div><br></div><div><br></div><div><br></div><div><br></div><div>
