Richard,
I dont know how to troubleshooting this issue. ( Midi Feedback)...
Im still have problems with LoopMIDI too with MUTE

Can you help me with my Unity 3D application or somebody in the forum ???
I want to share the application on github.
How i did:1 - I installed LoopMIDI and setup the Aerodrums to use LoopMIDI:
2 - Im running LoopMIDI:
3 - Unity MIDIJack Project:
On Unity3D i get the MIDIJack Project, and openned the 'Example Note.unity' scene, and create a 21 3D spheres, and set each to a MIDI Note with the 'Note Indicator.c' script.

And i set each 3D Sphere to a MIDI Note according to AERODRUMS Default MAP ( I made a clone ), the folling notes im using:
50,37,40,38,36,46,41,43,47,48,23,49,55,54,56,52,53,51,21, each note correspond to a drums individual element.

4 - Now i play the Unit y3D Application
Aerodrums cant send MIDI Notes to LOOPMIDI or LoopBe1 because are Muting the MIDI Channel !
Someone can help to solve this ? We can make custom Unity 3D applications for Aerodrums ( for Windows ).
I Will share the Source of Unity 3D Project here, pls Install Unity 3D last version ( 5.6.0f3 )
Just download the Project, Unzip and Open the Example Note.unity scene and hit Play
