Banjo

MIDI Looper designed for Live performances

Installation

Install it:

$ gem install banjo

Requirements

Mac OS X

You need to create virtual MIDI IAC inputs.

Open Audio Midi Setup

Then on the Window Menu click on Show MIDI Window

Double Click the IAC Driver icon and press the + where it says Ports, you should see something like this:

Each one of these inputs will work as a Channel for Banjo.

To make sure you have IAC inputs set up properly you can run the following command:

$ unimidi list

input:
0) Apple Inc. IAC Driver
2) Apple Inc. IAC Driver
4) Apple Inc. IAC Driver
6) Apple Inc. IAC Driver
output:
1) Apple Inc. IAC Driver
3) Apple Inc. IAC Driver
5) Apple Inc. IAC Driver
7) Apple Inc. IAC Driver

The unimidi list command will show you a list of the available IAC drivers that can be used with Banjo.

Usage

Promise to come back to write a proper guide, for now take a look at the included sample.

After you create the IAC driver open Garage Band.

Go to the sample/basic folder and run:

$ ruby song.rb

You should be able to listen some of the tones created by Banjo.

Edit channels/main_channel.rb on the sample/basic folder while the Banjo reactor is running and you will notice the changes in realtime.
