I use the sequencer Ambient Works with Renoise.
Regarding the Liquid system, I find him find benefits even if the interface is very austere, it is a little édudier the manual but it's going after.
The sounds are good, but I think they are not very well organized for browsing. The atmosphere did not seem very different at first glance. on the other hand sounds well suited to what I wanted to do music in the style electro-ambient.
I use it for two weeks so it is recent. I think so I could redo this choice because I was looking for surround sound abstract and that is what I wanted.
