The sounds in Ableton Live Intro, Standard and Suite are nearly identical with only small changes to EQ and delays.
The main difference is workflow and preparation, not performance. In Ableton Intro, you have 8 Scenes and 16 Tracks, and in Ableton Standard/Suite this is unlimited.
This means that in Ableton Intro your layered presets need to be assembled within an Instrument rack instead of spread across an entire Scene.
When you purchase Sunday Keys for Ableton you'll receive an Ableton Live Intro template as well as an Ableton Live Standard/Suite template.
