Ovation

Novation controllers meet Overtone

Why

Ovation is a thin abstraction layer between Overtone and Novation controllers. It leverages Component to help you build modular music apps with as little delving into MIDI specs as possible. Still very much a work in progress though.

Install

[ovation "0.1.1"]

Usage

Launchpad

Plug in your Launchpad, then start a REPL session. Define a simple event handler:

(require '[ovation.launchpad.core :as launchpad]
         '[ovation.launchpad.events :as events]
         '[ovation.launchpad.utils :as utils])
=> nil
(events/defevent echo-repl [:midi :note-on]
  [_]
  (fn [e]
    (let [n (:note e)]
      (println (format "cell %s, midi %s" (utils/note->xy n) n)))))
=> #'user/echo-repl

Define a config for the Launchpad component with :session as its default mode and bind your event handler to it:

(def config
  {:default-mode :session
   :modes {:session {:handlers [echo-repl]}}})
=> #'user/config

Start the component:

(require '[com.stuartsierra.component :as component])
=> nil
(component/start (launchpad/new-launchpad config))
=> ...

Try pattering on the Launchpad grid. The REPL should inform you of all the pressed buttons' coordinates and their corresponding MIDI values.

To do

• better docs;
• add support for all sorts of controllers!
