Using Kontakt 5 as a MIDI Arpeggiator with Maschine 2.0
Enable "Send MIDI Clock" in Maschine.
Enable "Receive MIDI Clock" in Kontakt
Set Kontakt 5 Virtual Input to Port A.
Set Kontakt 5 Virtual Output to on.
In the Engine section of Kontakt's preferences, set "Send MIDI notes to outside world" to "script generated notes".
Create a New Instrument in Kontakt.
Click the wrench icon in the upper lefthand corner of the instrument and then click on Script Editor tab on the right side of the instrument.
Click on the Preset button for the first empty script and load the Arpeggiator script.
Adjust the arpeggiator's parameters to taste.
Select the first sound slot of an empty group in Maschine. Name it ARP since this will be the MIDI triggering the arpeggiator in Kontakt.
Create a chord to be used as input to the arpeggiator.
Route this channel's MIDI output to the Kontakt 5 Virtual Input
Click on Sound 2 of this group, and set the MIDI Input to Kontakt 5 Virtual Output. Load an instrument into this slot and press play.
You should now hear a looping arpeggio. The one issue with this method is that you will have to stop playback when editing the MIDI note in the ARP Sound slot of Maschine. Then make sure that you select Sound 2 as the focus for the incoming MIDI.
