These Ableton racks are just fantastic.
They can give you out of the box sounds from the simplest of sources if that's what you're after. Similarly, if you want to learn new techniques or develop your existing knowledge, you can use the racks as a jumping off point for manipulating your sounds in your own unique way. You couldn't really ask for a better foundation to start from.
There's something here for everyone to get stuck into, from sound design beginners to seasoned veterans.
A must have addition for anyone using Ableton Live...
