You may already be familiar with the basics of using MIDI in Ableton Live, but there's so much more that it can do than simply recording from your MIDI device and triggering soft synths. In this short video from the course Ableton Live 202: Advanced MIDI Techniques, Live expert DJ Kiva explores some of the more advanced things you can do with MIDI, such as manipulating timing and playback direction.
Kiva starts by directing you to the Note section of a MIDI track, which is where you can access many of the MIDI tools and commands you're going to need. He then duplicates a MIDI drum beat before starting to edit it, so that he has copies of both versions to work with.
Using the Reverse command, you'll see that it's possible to quickly and easily create variations of beats and other parts. With the Invert command, you can swap the positions of the highest and lowest notes, flipping a part upside down. This can be great for chords and melodies. You can even double or halve the tempo of a clip with just a couple of clicks. This course is all about taking control of your MIDI tracks - check out the whole thing for a complete guide to becoming a MIDI master in Live!
