Leap Motion musical UI for closed eyes

How many musicians do you know that play with their eyes closed? Not many computer music apps allow this. Bloom is an exception.  http://www.generativemusic.com/bloom.html

As an exercise, I tried to make something like Bloom, using Leap Motion. With your eyes closed you can accurately position your hand at the level of eyes, shoulders, hips, etc., And you can quickly move to a point directly outward from your nose, or shoulders. This is the basis of sobriety tests.

The interface, works with a hand motion like sprinkling seeds. Every time you open your hand, it triggers a note based on the height of your hand. It also triggers one of the “Bloom”  circles at the XY position.

The prototype was done in Max/MSP Jitter. It was derived from a “bloom clone” project by John Mayrose at: http://www.johnmayrose.com/maxmsp.html

Here’s an example:

download

https://github.com/tkzic/max-projects

folder: bloom

patches

  • (main patch) circlething.maxpst
  • (poly~ sub-patch) FMPoly2~.maxpat
  • (Leap Motion main-patch) leap-finger-switch.maxpat
  • (Leap Motion sub-patch) leap-switch-test2.maxpat
externals and dependencies

Note: If you don’t have a Leap Motion sensor, you can use a mouse.

If you are using Leap Motion, download the aka.leapmotion external – and add it to your Max file path in options | file preferences: http://akamatsu.org/aka/max/objects/

instructions

(if not using Leap Motion sensor, skip to step 4)

  1. Plug in the Leap Motion sensor.
  2. Open leap-finger-switch.maxpat and click the “start” toggle. 
  3. Wave your hand around – it should be detected and displayed
  4. Open circlething.maxpat
  5. If using mouse, just click in the black “circlething” window to play.
  6. If using Leap Motion, click the message box to activate Leap Motion
  7. Then open and close your hand, over the sensor to play
  8. High notes are higher in the window.

How to use IFTTT from Max

IFTTT Twitter triggers are back!

Update – 5/20/2014 –

IFTTT has restored Twitter triggers. By using a Max Twitter client: https://reactivemusic.net/?p=7013 you can now connect Max with IFTTT

original post follows

A possibility with curl

A few notes…

It doesn’t appear that IFTTT has a public API.

One method would be to use intermediaries for example – sending email using php (see this post https://reactivemusic.net/?p=4840) Then IFTTT could pick up the trigger – for example, from gmail. Commands could be embedded in the subject or body of message.

Or you could simply use Twitter as the intermediary – using existing internet sensors methods: (see this post: https://reactivemusic.net/?p=5859)

Would this work in reverse?

Other methods:

temboo: The temboo API should be accessible via Max using a ruby server. Temboo has many common points of interaction with IFTTT

mashape: I think the same applies as with temboo.

Marcus Povey describes a workaround using web hooks: http://www.marcus-povey.co.uk/2012/11/07/using-webhooks-with-ifttt-com/

Another idea: http://forums.getpebble.com/discussion/5816/restful-api-iftt-integration-android

Or what about Zapier
