Control Change sends status byte and two data bytes. Program change messages send voice memory number to designate what timbres to play. Only the number of the program is sent, not the actual voice parameters. Channel Pressure or Aftertouch messages consist of a status byte and one data byte. Same paradigm as Polyphonic Aftertouch, but instead of having each key with its own Aftertouch value, now the value is associated with a specific channel.
Pitch bend messages consist of a status byte followed by two data bytes.
Pitch bend sends portamento values that will shift the pitch up or down as much as 8 octaves on some synthesizers. So one player can perform on the master synth, but only hear the slave. In this mode, the synth at receiving end may be played together with the master synth. Now one player plays the master and both the master and the slave are heard. All notes off messages turn all currently sounding notes off.
