Setting the configuration map
Midi organ diagram.
For each of its 32 outputs, the MTP-7 keeps a record of the MIDI channel number and MIDI note number that have together been assigned to control that output. MTP-7s are factory programmed with a configuration map corresponding to a rising chromatic scale on channel 1, starting at note number 36. If a different map is required, the unit must be placed into its configuration mode by holding down the configuration button whilst the board power is being switched on. Once in configuration mode, the indicator LED will flash rapidly and output number 1 will be switched on. Upon receipt of a MIDI ' note on' event, the MTP-7 will assign the note and channel numbers just received to output 1 In the configuration map, turn off output 1 and turn on output 2. The channel and note numbers of the next ‘note on' event received will be assigned to output 2, etc. This process will continue until 32 ‘note on' events have been received, at which point the MTP-7 will end its configuration mode and commence normal operation. If the same note and channel are allocated to more than one output, only the lowest numbered output will be mapped and the other outputs will be inactive.

A time interval of at least 20 milliseconds must be allowed between ' note on' events, which corresponds to a maximum tempo of 3000 bpm when using crotchet length notes,
The expression output voltage will be set to zero whilst the MTP-7 is in its configuration mode.
