Leap Motion QC PlugIn on GitHub

Hi all,

Thanks to @isthejayj who commissioned the latest version of my Leap Motion plugin, it's now available open source at : with the following patches.

  • Device: output keyed structures for the positions, directions, dimensions and gestures of hands and pointables.
  • Hands Reader: helper patch that avoid using "structures member" patch to get usable info.
  • Pointables Reader: helper patch that can output one or the five pointables of the provided hand structure and keep the pointables attached to an unique output.
  • 3D Transformation: works like the usual 3D transformation patch but with the hands and pointables coordinates.

Akai MPD 26 Controller Map

This patch lists all fo the buttons and faders from an Akai MPD 26 drum controller. By sniffing through all of the listings in the "Midi Notes Receiver" & "Midi Controller Receiver" (Faders & Pads respectively). It also lists the "pad sensitive" and straight boolean values from the pads.

I feel this is a pretty common controller so hopefully someone will find it handy!

Video Scratching

I am looking for a good way to "scratch video" in QC. By scratch, I mean analogous to Dj scratching in that one can alter the speed, position, and direction of a video on the fly using some fader, rotary, or other controller.

I have looked around, and it seems as though dust made it pretty good with his approach but I found no file to dive into.

The internet hints at using some sort of queue system to drive the video's position from what I have gathered.

Of course, if I hook up the mouse input to the rate, or selection start, the video becomes choppy. I know there is a good way to do this.

If someone could point me in the right direction that would be much appreciated

M-Audio Trigger Finger MIDI (Composition by farinuts)

Compatibility: 10.4, 10.5, 10.6
Required plugins:

This is a clip that provides MIDI control for the M-Audio Trigger Finger device.

I'd been tearing my hair out trying to get the pads configured - turns out they're notes (starting at C3) so you can't use MIDI Learn to map 'em. D'oh!

In hindsight, setup is pretty easy but I thought I'd share this since I didn't see much else in the way of support for the Trigger Finger in QC.

PS3 / SIXAXIS / DualShock controller mapping

Hello all,

Since recently getting a PS3 controller in the house, I decided to mess a bit with it this afternoon. The result is a macro that maps the incomprehensible values from the HID patch into something more readable. Attaching in case anyone could use it.

All in all, this is an amazingly expressive controller. All the main buttons have digital output as well as analog pressure sensing, and there are motion / tilt controls as well. I'm looking forward to hooking things up so I can play around with video mixing with the thing, even though the Xbox360 controller is a better fit for my hands, being bigger and all.

Anyway, the Bluetooth pairing went without hitch for me, though QC seems to not read the controller properly when the USB cable is attached, so I had to use it wirelessly. This is on Snow Leopard.

Lastly, can anyone help with making sense of the force outputs? Those are mapped to the outlets from the HID patch that reacted to motion, but I can't make sense of them with regards to which axes they use.
