//
// Prerequisites: Orca, Atom, Atom-hydra extension
//
// Open Atom, save and name as a .js file, and toggle atom-hydra from the packages menu
//
// Press CTRL+Alt+Enter to run this entire block of code in Hydra
//
// Orca section is at the bottom
//
// First, setup some handlers for Orca->Hydra communication
//
// set port to listen to osc messages.
// 49162 is the default OSC port that Orca sends from
msg.setPort(49162)
//init a single letter object for Hydra to use & to match the msg we send from Orca
z = [0,0,0,0]
//update on msg received
msg.on('/z', (args) => { z = args })
// end setup
//
// reference this object in hydra with indices
