Ah okay - makes sense. I'll try to reconfigure it. Thanks.

Pressing buttons on my Akai MIDIMIX, they show up in the MIDI Messages tab with channel of -31 for the press and -47 for the release. The status is always 144 for press and 128 for release. They have the correct CC number.

Fantastic

Another thing - sim/cockpit2/engine/actuators/prop_ratio_all is back to front, so could we have value_min = 1, value_max = 0, or a way to reverse the slider?

Thanks - that will be very useful

I had a go with XMidiCtrl and got it working to control all throttles via a slider and it seems good: { ch = 1, cc = 19, type = "sld", dataref="sim/cockpit2/engine/actuators/throttle_ratio_all", value_min = 0, value_max = 1 }, It doesn't seem to support arrays though, e.g. float[engines], so it can't control engine 1 or 2 separately. Am I missing something, or is this not currently implemented? I was trying to use throttle_ratio[0]. Thanks
