Adding Launchpad as a dependency in your project:
Usage
Launchpad works through an evented system. While you can do anything with those events launchpad.core setups some
useful defaults:
- When :session mode is lit allows infinite scrolling left or right (for greater than 8 phrases)
- When :session mode is lit allows infinite scrolling up or down (for binding more than 8 beats/samples)
- All top control buttons except :user1 / :user2 & :session
- Enter mode where each grid remembers keys pressed.
- Grid buttons simply toggle state/light on/off.
- :user1 & :user2
- Enter mode where there is no persistent grid state.
- Grid buttons trigger led/fn key-down and off with key-up
Simple example
(use 'overtone.live)
(use 'overtone.inst.drum)
(use 'launchpad.core)
(boot!)
;;Bind to the main grid
(bind :up :0x0 #(kick))
(bind :up :0x1 #(hat3))
;;Bind to the virtual grid @ y=1 (i.e session mode on and down btn once)
(bind [:up 1] :0x1 #(hat3))Plugins
For usage see examples in https://github.com/josephwilk/overtone.device.launchpad/blob/master/docs/demo.clj
- Metronome
- Mapping samples to a row
- Beat sequencing
- Beat sequencing with scroll update
Demo Examples
- Expressing drum/sample positions using LEDS (automatically synching to the beat).
- Adding a metronome cell which flashes with beat
- Turning a grid into an instruments
