vypyr-connector

VYPYR connector

With this module you can receive messages via events from your guitar amplifier (currently supports only Peavey VYPYR VIP series) and modify the current state of the amp by using HTTP requests or provided classes.

Installation

Installation uses node-gyp and requires Python 3.7 or higher.

npm i vypyr-connector

or

$ git clone https://github.com/KUNszg/vypyr-connector.git
$ cd vypyr-connector
$ npm i

Usage

This library deals with MIDI messages as JS Arrays for both input and output. Each element of array represents a state of current interface setup. For example:

[176, 10, 0]
// [program, ctrlr, value]

For full list of Peavey MIDI status codes see: https://github.com/KUNszg/vypyr-connector/blob/main/controls.json

Capturing input

const Midi = require("vypyr-connector");

const vypyr = new Midi();

// suitable port gets detected automatically
// if needed, provide a MIDI port in argument of the below method
// this is usually in range of 0 to 3
vypyr.connect();

vypyr.on('input', (timing, program, ctrlr, value) => {
    console.log(`
        program: ${program},
        ctrlr: ${ctrlr},
        value: ${value}
        timing: ${timing}`);
});

// Example response:
//
// program: 176,
// ctrlr: 16,
// value: 116
// timing: 0.05000
//
// program: 176,
// ctrlr: 16,
// value: 121
// timing: 0.15000
// ...

Sending output

const Midi = require("vypyr-connector");

// to select the port manually:
// const vypyr = new Midi(<your_port>);
const vypyr = new Midi();

console.log(vypyr.send(176, 10, 0))

// {
//   status: 200,
//   message: 'Message successfully sent to VYPYR USB Interface 1 on port id 1'
// }

Web API

const Midi = require("vypyr-connector");

const vypyr = new Midi()

// port 8080 is selected automatically
// if you wish to select another port:
// vypyr.express(<your_port>)
vypyr.express();
// => Server is running on port: 8080

# send the request
curl -X POST -H "program: 176" -H "ctrlr: 10" -H "value: 0" "http://localhost:8080/controller"

# Message successfully sent to VYPYR USB Interface 1 on port id 1
