14 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
users 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 eect 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 o (see ch. 2.2.3).
