      ddf.minim.ugens.Midi2Hz

public class Midi2Hz
extends UGen

Midi2Hz is a UGen that will convert a MIDI note number to a frequency in Hertz. This is useful if you want to drive the frequency input of an Oscil with something that generates MIDI notes.

uGenerate

protected void uGenerate(float[] channels)

Description copied from class: UGen

Implement this method when you extend UGen. It will be called when your UGen needs to generate one sample frame of audio. It is expected that you will assign values to the array and not simply modify the existing values. In the case where you write a UGen that takes audio input and modifies it, the pattern to follow is to have the first UGenInput you create be your audio input and then in uGenerate you will use the getLastValues method of your audio UGenInput to retrieve the audio you want to modify, which you will then modify however you need to, assigning the result to the values in channels.

Specified by:

uGenerate in class UGen

Parameters:

channels - an array representing one sample frame.
