-### Web MIDI
-
-#### Experimental! 
-
-Hydra can be used with [Web MIDI](https://webaudio.github.io/web-midi-api/) for an extra layer of control to your visuals.  At this time this requires some running of code on the
-browser console (Press F12 in Chrome to access).  This page only considers MIDI Continuous Controllers (CC) but other types of data may be accessible.
-
-This is a generic script that doesn't care what Midi Channel you're broadcasting on and maps a normalized value 0.0-1.0 into an array named cc. 
-
-### Console Script
-This portion should be ran in the console & will register Web MIDI & map the incoming CC data to a set of parameters.  For simplicity, these
-parameters are named to match the CC number.  The CC values are normally in a range from 0-127, but we've also normalized them to be in a range of 0.0-1.0.
-
-```
-// register WebMIDI
-navigator.requestMIDIAccess()
-    .then(onMIDISuccess, onMIDIFailure);
-
-function onMIDISuccess(midiAccess) {
-    console.log(midiAccess);
-    var inputs = midiAccess.inputs;
-    var outputs = midiAccess.outputs;
-    for (var input of midiAccess.inputs.values()){
-        input.onmidimessage = getMIDIMessage;
-    }
-}
-
-function onMIDIFailure() {
-    console.log('Could not access your MIDI devices.');
-}
-
-//create an array to hold our cc values and init to a normalized value
-var cc=Array(128).fill(0.5)
-
-getMIDIMessage = function(midiMessage) {
-    var arr = midiMessage.data    
-    var index = arr[1]
-    //console.log('Midi received on cc#' + index + ' value:' + arr[2])    // uncomment to monitor incoming Midi
-    var val = (arr[2]+1)/128.0  // normalize CC values to 0.0 - 1.0
-    cc[index]=val
-}
-```
-
-### Hydra script
-Now that these controls have been assigned to the cc[] array, we can start using them in Hydra.  As we've normalized the values 0-1 we can use
-as-is with most functions or quickly remap them with various math.  
-```
-// example midi mappings - Korg NanoKontrol2 CCs
-
-// color controls with first three knobs
-noise(4).color( ()=>cc[16], ()=>cc[17], ()=>cc[18] ).out()
-
-// rotate & scale with first two faders
-osc(10,0.2,0.5).rotate( ()=>(cc[0]*6.28)-3.14 ).scale( ()=>(cc[1]) ).out()
-
-```
