AMG has released a reduced price, content-free, version of ONE and also released a demo version.
Low-Cost downloadable version of ONE
If you're into using loops but really don't feel like you need more of them then the latest version of ONE might be ideal for you. Enjoy all the features of ONE without having to buy any content - just use all your existing REX, ACID, WAV and Aiff files and have the option to add Expansion Libraries for ONE later on when you find titles that are up your street.
The downloadable version is available now for the special introductory price of £60 ($100 / €90).
Demo Version of ONE
The demo version of ONE is available to download in all it's available formats. You can't import anything and it times out but there are a few demo files you can play with that are also available to download.
