Looking briefly at the device I can see no immediate reasons why it wouldn't work, and I have actually just purchased one out of curiosity.

I have not seen the Teensy LC, It appears to be an option I didn't have at the time of writing this article. This has come in handy for users who insist on scrolling through an electronic version of the script, or choose to fire up safari and check-in with their social network. The MIDI solution meant that QLab received the commands regardless of the active application you were working on. I found the same result, together with the looming concern that if any application (or user) took focus away from QLab, then the keystrokes would be issued to that application instead. I too experimented with keyboard emulation as you have. Comments, questions, and suggestions are welcome.įirstly apologies for the delay in responding to you, It's been move weekend so I've been rather preoccupied.
#Qlab midi trigger code#
The QLab MIDI Controller Arduino code will follow in part III. The inclusion of the specific Bulgin connectors are purely optional, I chose them because the USB cable can be ‘locked’ in place, and a standard Mini USB can also be accepted. The Teensy and wire ends were then mounted onto a piece of strip-board Each of the Buttons was installed and four cables were run to each of them. The enclosure front was cut to accommodate the three buttons, the rear face was cut to accept the panel mounted USB receptacle (apologies for the lack of photos). the second press will cancel the flash and re-illuminate the button. To reflect this, the first press of the stop button will cause the button to flash for three seconds. If the button is pressed a second time the track will stop immediately. The time of this fade can be modified in the preferences. QLab will fade all active cues when the ‘Panic’ button is pressed. The LED on this button will extinguish while the button is pressed. The next button will send a different note to the computer when pressed. During this time the go button will blink 3 times. To do this it sends a MIDI note to the computer when the button is pressed, and turns the note off when the button is released. The Go button is intended to fire the currently selected cue. When powered up all three of the buttons will illuminate. Please let me know if you have any questions, comments or suggestions. I’ve put together a very rough schematic in Fritzing. Internal pull-ups negate the need to resistors on the switches. The wiring for the controller is very simple. Please read Part I QLab Midi Controller for an introduction to the project.
