Masher - video
The Masher is an FX Sequencer / FX Device made with Ableton Live 8 for the Novation Launchpad. Send any track you want to the masher and start cutting, mashing, repeating, looping, ... This works great for giving a track an extra boost when playing live or even for mixing/mashing two tracks in an original way.
You can sequence 4 different effects and the original track and you have a pad on the LP to flip between the sequenced/effected track and the clear and original track. On top of that you also have 6 master effects and 2 beat repeaters.
