Transport Buttons / MMC / MIDI Machine Control
The transport section of the VersaKey include the following buttons:
[<<],[>>],[O],[stop],[play]
These buttons can be used to trigger specific recording controls via MIDI. The function of
these buttons will depend on whether or not the hardware or software being used is able to
support them. Using the included Bitwig software, every transport button can be used to
trigger the DAW recording controls. But it is possible that these buttons will not function as
well when used in combination with other software.
Extra Information About GM, Bank & Program
Changes
The original GM MIDI specification was initially designed to allow Program Change access
to just 128 different sounds via specific identifying values (0-127). As MIDI equipment
became more advanced and able to produce more sounds, Bank Change messages were
added to the specifications to allow access to much more than 128 sounds. Each bank
has128 possible different sound patches that can be accessed using the standard Program
Change command. Using the more extensive 14-bit Bank Change command, 16,384 banks
are made available, each with 128 sound patches. Technically speaking, the first 7 bits of
the 14-bit Bank Change message is sent in a single bite known as the Bank LSB. The last 7
bits are known as the Bank MSB. The Bank LSB is the most used. This allows for 128 bank
transfers, and usually a Bank MSB is not needed.
You’ll notice that almost all MIDI equipment responds to Program Change commands and
many are organised according to the GM list. All General MIDI equipment organises all of
the different sounds in the same way, so that, for example, the piano sounds are always
found in the same place, the strings are always found in the same place, the drum sounds
are always found in the same place, and so on. All GM devices (including hardware as well
as software sound modules) are clearly labelled so that you’re aware that their sounds are
organised in the general GM MIDI structure. When a GM device receives a MIDI program
change command, it will call up the same sound as any other GM device: the expected
sound as specified by the GM list. The difference is that non-GM devices fed with the same
command, will call up an entirely different and unique sound. Since the sounds of non-GM
devices are not arranged in any specific order, you need to check the device itself to find the
