7.3.1 PRESET (1)

Leftmost button in the upper row

The PRESET-menu serves to call up the user preset (1) or one of the 16 factory presets (2-17). Each preset

contains all data about the 4 keyboard zones, i.e. the corresponding keyboard ranges, Midi-channels,

transpositions, allocation and activation of the controllers and the velocity-response curves.

When entering this menu the LED display will show the number of the currently selected preset. A new preset is

called up by pressing one of the keyboard keys which have been assigned the numbers 1 through 17. The new

preset number will appear on the display for several seconds and the keyboard goes into PLAY-mode.

You have to distinguish between the user preset 1 and the 16 factory presets 2-17. If you call up preset 1 the

user defined preset memory is selected. If you modify any parameter in the menus 3-7 after calling up preset 1

the change is written immediately to the user preset and is available after turning the keyboard off and on again.

If you select one of the factory presets 2-17 the keyboard parameters may be changed in the same way but the

changes are lost after turning the LMK2+ off. Information about the keyboard configurations contained in the 16

factory presets can be found in Appendix D. If individual parameter settings shall be available after turning the

LMK2+ off and on again you have to call up preset 1 and modify the parameters as required. When turning the

keyboard on next time the user preset 1 is called up automatically and thus the required individual parameter

settings.

7.3.2 PROGRAM CHANGE / BANK / REALTIME (2)

2nd button in the upper row

This menu serves to send Midi-program change, Midi-bank select and Midi-real time messages. When entering

this menu the number of the selected keyboard zone (important for the Midi-channel on which the program

change and bank instructions will be sent) will be shown on the left of the LED display, the number of the

presently selected number range on the right (1 = 1...32, 2 = 33-64, 3 = 65-96, 4 = 97-128).

Sending a program change instruction

The programs are organized into 4 ranges of 32 programs each. Number range 1 corresponds to programs 1-

32, range 2 to 33-64, range 3 to 65-96 and range 4 to 97-128. The number ranges are selected with the first

four white keys of the lowest octave of the keyboard (C, D, E, F). When switching range with one of these keys

the range number 1...4 is shown on the display. However, no program change instruction is sent until one of the

keys corresponding to the numbers 1-32 on the keyboard has been pressed. The program number sent will

appear on the display for several seconds, then the keyboard will go into PLAY-mode. The program-number will

be sent on the Midi-channel which has been assigned to the currently selected keyboard zone.

Sending a program bank instruction

To switch from program change mode to program bank mode you have to press one of the first two black keys

in the lower octave. The CIS key selects the controller #0 mode, DIS the controller #32 mode. If you press after

that one of the number keys 1...32 a controller #0 or #32 instruction is sent. The range is selected in the same

way as for the program change mode with the first 4 white keys.

Unfortunately there is one difference between the data range of program change and program bank instructions.

The program change number range is 1...128, only a few manufacturers use the range 0...127. However the

data range of controller #0 and #32 is 0...127. So you have to add 1 to the controller data required to get the

right key number (key number 1 corresponds to program change data 1 but to controller data 0). This

inconsistency is found in Midi unfortunately very often. The internal data range in Midi is always starting at 0, but

in the everyday usage some Midi parameters start at 1 (e.g. Midi channel, program change), others at 0 (e.g.

controller numbers).

The complete bank instruction consists of a controller #0 event followed by a controller #32 event. Thus up to

16384 (=128 x 128) different program banks theoretically are available. A program change instruction following

the bank select instruction selects one of 128 sounds (programs) within the selected bank. Thus up to 2097152

(= 128 x 16384) sounds theoretically are available. Of course no Midi expander is able to produce 2097152

different sounds. If your expander, synthesizer or sampler recognizes the program bank instruction can be

found in the Midi implementation chart of the unit. Normally only a few combinations of controller #0 and #32 are

allowed to select one of the program banks availabe. Some manufacturers also use only Controller #0 or #32 to

select a program bank.
