MIDI FOOT CONTROLLER FCB1010 User Manual
Almost all devices have a list enclosed which shows the program change number
versus preset number assignment. Some units even allow you to freely assign
program change commands to preset numbers. Please see the corresponding
user's manual for detailed information.
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).
