Ableton Push has an amazing sequencer for drums. Live has also said that 9.1 will have a melodic sequencer for push as part of the update. In the mean time you might want to sequence melody, or have another approach to it. Well then this guy has the answer for you. 

 Andrew Orenda has put together this amazing M4L patch to give you some new sequencing skills. It’s called the Audio Modder and is free to download from his site. Below is a video walk through of the device and what it can do.  I’ve played with it a little and love the ease of use and how you can quickly start to sequence melodies with your push.

Thanks Andrew Orenda and keep up the awesome push packs.
