4.2.4 Running status
Since the MIDI standard uses a serial transmission format, i.e.
transmits data successively, it was soon found that the
transmission rate is too low if the system is exploited to its full
capacity. To make up for an audibly delayed transmission of MIDI
data, the so-called running status was introduced, which
suppresses the status byte in two or more identical MIDI
messages that follow each other. For example, if the data bytes
of a controller (e.g. volume) are changed continuously, the
corresponding status byte is sent only once. Only the data byte
changes are transmitted, as long as another status byte is sent,
i.e. in each message transmitted you can eliminate 8 bits. This is
also the reason why NOTE OFF messages are no longer used.
When a keyboard player plays a scale on a keyboard and sends
these data via MIDI to a computer, each NOTE ON message
would be followed by a NOTE OFF message, each time a key is
released. The running status would identify the NOTE OFF
message as a new status byte and hence send it, which results
in a data amount of 8 notes times 8 bits, i.e. 192 bits. Since NOTE
ON messages belong to those MIDI messages that are used
most often, it was decided to send NOTE ON messages with
zero velocity instead. The audible effect is the same, but in the
Running Status the data amount can be reduced by 7 times 8
bits, i.e. 56 bits. As a consequence, the overall data amount
produced by the scale mentioned above is only 136 bits. With the
FCB1010 you are free to switch the Running Status feature on
or off (see ch. 2.2.3).
