QLab Four Button MIDI Controller

I was contacted by a QLab user who wanted a custom controller. He wanted a device with a 5 Pin DIN MIDI output and rectangular buttons for go, stop, next, and previous. It was a bit of a rush as well, and since he wanted something similar to the MIDI Controller 4 Button LC I had previously built, I started with that as the base.

I did up a quick sketch to make sure I knew what I was building (mainly to determine button spacing) and then got to work making it. We just used four different MIDI noteOn events for the buttons. I should also note that while USB is used to power the device it can also operate as a USB MIDI device. This means you can choose between the 5 Pin MIDI output, or the USB MIDI output, or use both… going to two different computers even. I think that’s a nice feature.

The one snag on this project (which I blame on doing it very quickly) was that I accidentally swapped the position of the red and green buttons! I did not notice until it shipped, and offered to correct it if needed. It turned out it was very easy for the recipient to pop off the red and green covers and swap them on his end. Problem solved!

The one other think I did here was separate the cover from the enclosure so it could print separately, which makes it a bit more modular of a system for future changes, and also allows printing without support. So, less material, and faster production. Nice. The black screws on the top are also a good fit.

We also used a USB-C connection for this one. I’m normally not a fan of USB-C but if requested it’s certainly an option that can be provided.
