Maybe this will help. Yes, I had the free labs version and this immediately sounded sweeter (to my untrained ears) with more flexibility. And the new Cinematic is just under 2 GB
The question maybe between the two Originals offering. Here is what SpitFire is saying...
Originals Felt Piano has a closer, more delicate sound, with three close signals (Condenser, Ribbon and Hammers). It was recorded on the dry stage at Spitfire Studios, performed by jazz legend and Mercury Prize nominee Gwilym Simcock. It features 10 presets, from close to synth-like, plus ADSR and sustain pedal level control.
Cinematic Soft Piano was recorded at Lyndhurst Hall, AIR Studios, performed by Spitfire Audio co-founder and composer Christian Henson. It also provides a Close signal for a more intimate sound, while the Mix signal goes all the way up to a reverberant, widescreen sound.
