Program Change
The PM5000 employs a number of “strategies” to ensure
full functionality with the standard MIDI
implementation. For example, in order to be able to
handle recall of all 1,000 PM5000 scenes via MIDI
program change commands, bank select commands (a
type of control change command) are used in
conjunction with the program change messages in the
same way that they are used in many synthesizers and
tone modules. The parameters described below can be
used to create a “program change table” that specifies
which scene numbers will be recalled by which MIDI
bank and program change numbers. The reverse is true,
too: when a scene is recalled via the PM5000 controls
the corresponding bank and program change numbers
can be transmitted to an external MIDI device.
In order to provide the most flexible operation with
external MIDI devices, the PM5000 provides two MIDI
program change modes: SINGLE and MULTI. Sixteen
MIDI channels (1 through 16) are available for
transmission and reception of MIDI commands, and in
large MIDI setups it is common to assign a different
channel number to each MIDI device so that programs
can be recalled independently on each device.
Also part of the standard MIDI implementation is an
“OMNI” mode which, when enabled, allows commands
to be received on any or all 16 MIDI channels. When the
OMNI mode is disable MIDI commands can only be
received via the device’s specified MIDI channel(s). The
PM5000 takes advantage of this situation in the SINGLE
mode, using four combinations of bank select number,
OMNI ON/OFF status, and a separately specifiable
MIDI receive channel to specify how the program
change table will be used for scene recall.
