Some hardware like audio interfaces but also some apps give you a free version of Ableton Live Lite. The cheapest way to get your hands on Live Lite is to buy the iPhone app called Triqtraq - Jam Sequencer of Zaplin Music, which is around 7 US$.
So here's what you have to do...
- Buy Triqtraq - Jam Sequencer for 7 US$ from the iPhone app store and install it
- Open Triqtrack on your iPhone
- Press MENU at the right bottom
- Select EXPORT in the menu
- On the next page, at EXPORT AS select Abelton Live Set
- On that same page select "Don't own Live? Get Abelton Live 10 Lite"
- A new page appears where you can fill in your email and submit
- You will recieve an email with a free licence for Live Lite

This is how the pages in Triqtraq look.
