51. wing conditions will apply 1 The delay time is not dependent upon the base parameter value Only the MIDI tempo period and patch information will affect it 2 In order to preserve an acceptable rhythmic relationship when the calculated delay value exceeds the maximum delay value permissible by the LXP 5 it will be repeatedly cut in half until it is within the stated delay parameter range 3 When enabling a patch from MIDI LEARN Mode the MIDI patch scale is related to the effective note duration of the delay as shown in the following table 3 12 MIDI Operation ADJUST NOTE Knob Position DURATION Half Note Dotted Quarter Half Triplet Quarter Note Dotted Eighth Quarter Triplet Eighth Note Dotted Sixteenth Eighth Triplet Sixteenth Sixteenth Triplet Thirty second OMONOORWNO a z 0 Disabling a Global Patch Global patches can be disabled from the front panel of the LXP 5 To do this simply turn FUNCTION to EDIT A turn SELECT to position MAX and set ADJUST according to the following table ADJUST GLOBAL PATCH Knob Position EDIT Disables all global patches Re enables a global patch after moving associated MIDI controller Re enables all global patches immediately This feature can only disable and re enable all existing global patches It cannot be used to create new global patches Note The global patch sources for parameters 0 22 are intitialized at the factory to correspond to MIDI controller
