K-M IX H ARDWARE74D IAMOND P ADK-Mix’s diamond pad behaves in the same manner as the buttons do when in MIDI banks; each ofthe four buttons can act as momentary switches or toggle switches.• Each of the four diamond pad buttons can output MIDI notes.• The specific MIDI note each button outputs, and whether the buttons are momentary or toggleswitches, is set in the K-Mix Editor’s MIDI Tab.• When set to “momentary”, the buttons will output a MIDI note with a velocity of 127 whenpressed, then output a MIDI note with a velocity of 0 when released.• When set to “toggle”, the buttons will output a MIDI note with a velocity of 127 the first time thebutton is pressed (toggled on), then output a MIDI note with a velocity of 0 the next time it ispressed (toggled off).• The button’s LED will light up red when pressed (or toggled on), and will return to green whenreleased (or toggled off).4.3.2.2 – D IAMOND P AD I N M IX B ANKK-Mix is able to output a few special MIDI messages when in the Mix bank. Whenever K-Mix is in the Mixbank, the diamond pad buttons will output MCU (Mackie Control Universal) transport control messages.• The diamond pad buttons are labelled with the corresponding transport control message theyoutput when pressed.• = Play, = Stop, = Rewind, and = Record,.• K-Mix will only output these transport messages when in the Mix bank; it will output standard MIDInotes when in any of the three MIDI banks.4.3.2.3 – MIDI E XPANDER O UTPUTIf a MIDI Expander is connected to K-Mix, all MIDI output by K-Mix will be sent out of the MIDIExpander’s MIDI Out jack (in addition to sending to Port 3: K-Mix Control Surface).MIDI can also be sent directly out the Expander’s MIDI Out jack from a connected computer/tablet bysending MIDI to Port 2: K-Mix Expander.
