Allows continuously changing information such as pitch wheel or breath controller information to be passed over the MIDI line. Continuous controllers use large amounts of memory when recorded into a MIDI sequencer. Some standard MIDI Continuous Controller numbers are listed below.

PWH = Pitch Wheel
CHP = Pressure
1 = Modulation Wheel
2 = Breath Controller
3 = (Pressure on Rev. 1 DX7)
4 = Foot Pedal
5 = Portamento Time
6 = Data Entry
7 = Volume
8 = Balance
10 = Pan
11 = Expression Controller
16-19 = General purpose controllers 1-4 (High Res.)
64 = Sustain Switch (on/off)
65 = Portamento Switch (on/off)
66 = Sustenuto (chord hold)
67 = Soft Pedal (on/off)
69 = Hold Pedal 2 (on/off)
80-83 = General purpose controllers 5-8 (Low Res.)
91 = External Effects Depth
92 = Tremolo Depth
93 = Chorus Depth
94 = Detune
95 = Phaser Depth
96 = Data Increment
97 = Data Decrement
