Built for Music Hack Day London 2013.
Use a Novation Launchpad and the Twilio API to play looped sounds on up to eight phones.
You'll need a Twilio account, an ngrok account, a list of up to eight sound files hosted somewhere and a list of up to eight phone numbers.
$ npm install telepad
This adds a binary named telepad to ./node_modules/.bin, which should be in your $PATH.
Run ngrok on a port of your choice:
$ ngrok 9999
ngrok will assign you an address. Now you need a JSON config file as follows:
{
"midi": {
"port": 0
},
"ngrok": {
"address": "http://abcabc.ngrok.com",
"port": 9999
},
"twilio": {
"sid": "abcabc",
"token": "defdef",
"number": "+440000000000"
},
"sounds": [
"https://s3-us-west-2.amazonaws.com/telepad/mp3-128-cropped/Glockenspiel+A1.mp3",
"https://s3-us-west-2.amazonaws.com/telepad/mp3-128-cropped/Glockenspiel+B1.mp3",
"https://s3-us-west-2.amazonaws.com/telepad/mp3-128-cropped/Glockenspiel+D1.mp3",
"https://s3-us-west-2.amazonaws.com/telepad/mp3-128-cropped/Glockenspiel+D2.mp3",

"https://s3-us-west-2.amazonaws.com/telepad/mp3-128-cropped/Glockenspiel+F%231.mp3",
"https://s3-us-west-2.amazonaws.com/telepad/mp3-128-cropped/Glockenspiel+F%232.mp3"
],
"numbers": [
"+440000000000",
"+440000000000",
"+440000000000",
"+440000000000",
"+440000000000",
"+440000000000",
"+440000000000",
"+440000000000"
]
}Then start the Telepad server:
$ telepad
The config file is expected to be named config.json and located in the
current working directory. If it's not, you can pass in a relative path.
$ telepad some/other/file.json
The special buttons on the right of the Launchpad will light up red for each phone number in your config. Press them to make a call, you'll see them turn green.
Each row corresponds to a phone and each button corresponds to a sound from your config! Pressing the special buttons again will hang up the calls.
With thanks to Syd Lawrence for midi-launchpad and his helpful advice.
