Notes: ' $x$ ' in status byte hex value stands for a channel number.
(a) 1) Is the Pitch Bend MIDI message a Channel Message?
2) The Pitch Bend opcode in MIDI is followed by two data bytes specifying how the control is to be altered. How many bits of accuracy does this amount of data correspond to? Why?
3) The MIDI communications standard specifies 31250 bps (bits per sec); how many Pitch Bend messages could be sent in 3 seconds if the message stream consisted only of Pitch Bend messages?
(b) The note "A above Middle C" (with frequency $440 \mathrm{~Hz}$ is note 69 in General MIDI. What MIDI bytes (in hex) should be sent to play a note twice the frequency of (i.e., one octave above) "A above Middle C" at maximum volume on channel 1? (Don't include start/stop bits.) Information: An octave is 12 steps on a piano, i.e., 12 notes up.
