Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

MIDI Device Support: Getting 'None' when trying to access the MIDIDevice Controller value

I'm trying to utilize the MIDI Device Support plugin and I have my blueprint sent up the following way:

However when I try to run it, I get this error:

'ExecuteUbergraph_MIDIPROJECT' from node: Bind Event to OnMIDIEvent in graph: EventGraph in object: MIDIPROJECT with description: Accessed None trying to read property Midi Device'.

I've tried a Print String off of the 'Return Value' pin on the 'Create MIDIDevice Controller' node and it's reading as 'None'. Any help would be greatly appreciated.

1 answer: sort voted first

I struggled with this a bit too. Turned out that it was something weird with my device drivers and once I'd sorted that out everything worked quite well. For reference, here is a debug blueprint that I put in my level blueprint. It lists all the devices recognized as midi, tries to make a valid MidiDeviceController, then tells you whether that was successful. Then it attaches a debug event. Works on my setup - Win 10, UE 4.16 pre2, Allen & Heath Xone:K1.
