I use Ableton LIVE as my main platform and specifically look for great synth and effects devices, (free or paid), that work as direct devices in LIVE (as opposed to VST, AU etc).
I came across a new company called FORS (fors.fm) and got a copy of the Chiral synth which sounds amazing, is well designed, easy to use very unique and supports MPE. It's not like anything else and I plan to buy their other devices based on Chiral, especially Doublet which is only 15EUR.
So many LIVE devices are less than well designed (some just downright awful) and this one is elegant and very well done.
Chiral is totally worth the 29 EUR IMO and I think you need to have Max for Live / Live Suite. YMMV of course but color me impressed.
