MIDI trigger Q in QLab through Element Bump Button

midi comes in different flavours. the ones relevant here are Midi Show Control (MSC) and Midi Notes.

midi show control is automatically sent from certain events, like when firing a cue and when firing a macro. Eos-family consoles don't seem to send MSC when firing a sub.

but, you can make a sub send a midi notes command: type [Sub] 1 {Execute} [MoreSK] {Midi Data} 90 01 7F [Enter]. every time you press the sub's bump button, it will send this midi command.

midi notes work like this:
you always have three hex pairs. e.g. 90 01 7f
9 = Midi Note On
0 = Channel 1 (range from 0-15, with an offset of 1)
01 = Note 1, e.g. the lowest note. range from 01 to 7F, so 127 different notes)
7F = velocity, this is often ignored, it just needs to be NOT 00
