Launchpad + Raspberry Pi

January 20th, 2013 3 comments

Hi there. I got Novation Launchpad connected with the Raspberry Pi running the Raspbian installation and talking with Pure Data.

I wanted to be able to load PD patches on the Pi, let it run under the hood of the launchpad and output custom midi.

 

 

 

 

 

These were the steps I took:

1. Installed raspbian on the sd card and got the pi booted up. If you are having trouble check out the Raspbian FAQ

2. Got PureData installed and got PD talking with alsa.

$ sudo apt-get update
$ sudo apt-get install puredata

3. Got dependancies and configured the launchpad executable driver “launchpadd” on the pi.

$ sudo apt-get install libusb-1.0-0-dev
$ sudo apt-get install automake

$ autoreconf -i
$ ./configure
$ make install

4. Installed other drivers for other perferials, I used the MidiSport Uno usb midi cable.

5. Loaded up my PD skeches on the Raspberry Pi and started them up.

6. To have the Launchpadd executable run at startup I changed the /.profile file in linux to start the “launchpadd” program at login.

Some of the things I would like to do to finish this project is to build an awsome enclosure to hold the pi and the launchpad also use the gpio pins for midi instead of the usb to midi converter.

I’m using a sketch that changes the output channel of the LP with the top row of buttons. its like having 8x launchpads.

Here’s a zip including all the readme files, launchpadd driver and a pd sketch to test the functionality of the launchpad. launchberrypi_files.zip

also here’s a link to get pd-extended running on the pi PD_extended_on_RaspberryPi

Launchpad Linux updates in ALSA

July 7th, 2012 No comments

So there has been a lot of work with getting the launchpad running on linux.
 

We talked about it a couple years ago and there has been some really cool advancements that I wanted to share with everyone.

 

ALSA has now supported the Launchpad since V1.0.24 so that’s exciting news! AlSA changelog, the Advanced Linux Sound Architecture is bundled with Ubuntu/Debian desktop versions of Linux.
 

A homebrew kernel for midi support in Ubuntu “by Will Scott” get the project at the Launchpadd Google code page.

8 band graphic EQ for the Launchpad

February 17th, 2010 3 comments

I thought it would be cool to have a graphic eq display on the launchpad so I built this 8 band graphic EQ. As of now, it has these controls:

1. Adjustable peak filters on each band
2. Individual band volume controls for those unruly frequencies

Download 8BandEQ2.0 for the Novation Launchpad for (Windows).


(forgive the cheap webcam framerate, it actually preforms better then this video can reproduce)

This is version 2.0. I will continue to update and add more features. I hope you enjoy 8bandGraphicEQ for the Launchpad.
