@motulogic2018 You addressed the wrong person. Here's the post^SmilesLots wrote:I have a complete midnam for the Motif Rack XS. Maybe you could use that with Cherry Picker to create a full idnam. BTW when you install Motu's software for whatever MIDI interface you have, it will create the missing folder (and a lot more). I have not checked if the midnam for the synth you have is there.but it may be. Let me go to that computer.
OK. I checked and yes I do have a midnam for the Motif XS 8. So it gets installed once you download and install Motu's software for a MIDI interface - like the MTP-AV. You may simply be missing that driver and its associated files.
