Thanks for the post. I'd like to help! Make sure you're using Ableton Live 9.2 or higher. That added control surface support for the Alesis V and VI keyboards. That means Ableton should automatically map to your controller when connected. On top of that, you need to select a VST inside Ableton to produce sound. Here's a guide to help you out with How to Use VST Plugins in Ableton Live.
