Note On message; nnnn = channel, kkkkkkk = note number and vvvvvvv = velocity.
If effect = arpeggiator sequence, note number is used to transpose the sequence down or
up. Number 60 = no transposition.
If effect = any of the MIDI options, then the effect’s specified MIDI data source is used to
modulate the frequency of the effect’s specified filter type.

Control Change; nnnn = channel, ccccccc = control number, vvvvvvv= value.
If control number = 32 (bank select) and value = 0, Factory Preset bank is selected; if
value = 1, User Preset bank is selected. If the specified control bank select is different
than of the active preset, the active preset is changed to the respective preset for selected
bank, factory or user. Power-up bank selection depends on the active preset on power-up.
If effect = “MIDI Controller to Filter” or “MIDI Controller to Flanger,” then the data value
of control number 1, 11, 16, 70 or 74 modulate filter or flanger frequency.

controller message. If ppppppp is greater than 99, message is ignored.
