Building upon the methods explored here, I've been experimenting with using node-red's Twitter node to interface directly with ruby files in Sonic Pi by means of shell scripting. By creating multiple instances of the Twitter nodes in a single flow, I can set unique search terms, strings, hash tags, etc per node, which correspond to … Continue reading Further Adventures with Twitter, node-red and Sonic Pi
Using QLab 3, Left Coast Mac programmed a continuous video wall controller for Axon's Seattle office lobby. Using event automation via AppleScript and OSC controls to control the startup, running, and shutdown of the video wall on a daily basis, the installation has been running continuously since summer of 2015. More here.
UPDATE 7/10/17 - Check out the contributed module from Sam Levey, with nodes to control QLab via OSC messages and a node to control node-red from QLab: https://www.npmjs.com/package/node-red-contrib-qlab This eliminates some steps from the method described below. ORIGINAL: Utilizing node-RED, QLab can respond to hash tags, text strings, etc via OSC messages and UDP packets. … Continue reading Control QLab with Twitter
Make a texting applet for QLab and QDisplay – Created to solve the problem of verbal communication between a mix engineer and wireless engineer during performances. Using AppleScript, QLab and QDisplay, create a non-verbal communication method to allow the A2 to warn the A1 of wireless mic dropouts, and the A1 to acknowledge receipt without getting … Continue reading Make a texting applet for QLab and QDisplay
