Use Arduino Uno (or Mega) and the USB Host Shield to transform your Novation Launchpad S into a stand-alone (no need for a computer) midi "keyboard" similar to Ableton's Push instrument mode.

Developed by Mauricio Maisterrena.
-Hardware:
- Novation Launchpad S or mini (haven't tested other versions but it might work as well on the original and the RGB versions)
- Arduino Uno or Mega
- Arduino USB Host Shields from Circuitsathome.com (or replica)
- Female MIDI jack
- 220 ohm resistor
- Wires
-Software:
-
Arduino MIDI library http://playground.arduino.cc/Main/MIDILibrary
-
for use with USB Host Shield 2.0 from Circuitsathome.com https://github.com/felis/USB_Host_Shield_2.0
-
Yuuichi Akagawa's USB MIDI library https://github.com/YuuichiAkagawa/USBH_MIDI
- Plug the USB Host Shield to your Arduino .
- To send the midi from the Arduino follow the diagram shown in this page https://www.arduino.cc/en/Tutorial/Midi
- Install the libraries mentioned on the requirements secction by followinng the instructions in this page http://arduino.cc/en/Guide/Libraries
- Upload the Launchduino Pro File tio your Arduino. TIP: Make sure that Tx and Rx pins on the arduino are disconnected when uploading.
- Connect your Lauchpad to the USB Host Shield.
- Have fun.
- Send Midi notes using Launchpad S grid.
- 5 Diferent Scales to choose from (Mayor, Minor, Flamenco, Blues, Chromatic) plus a Drum set.
- Leds display the root notes (yellow) ant fifths (green) of the selected scale.
- Octave up and down buttons.
- Change the root note of the selected scale by presing a button.
- Send midi to 3 diffecrent midi channels plus an additional channel for drums.
- Change midi channel just by pressing the corresponding button.
- Midi Panic Button.
