Automate sinusoidal MIDI pitchbend
This patch demonstrates one way to create a sinusoidal pattern of numbers in Max.
The MSP object cycle~ generates a sinusoidal waveform at the audio sampling rate, and the snapshot~ object reports the value of its input at regular intervals—every 40 milliseconds in this example. The range of cycle~ is -1 to 1, so we add 1 to it to offset the range to be 0 to 2, and we then multiply it by 64 to get numbers in a range between 0 and 128. The slider object will convert that float to an int (as would the bendout object if it received the float directly), and transmits the number out as a MIDI pitchbend message.
