The 8 layer dry samples are all 8 layers with AND 8 layers without sustain (or release).
The only 4 layer programs are those with AND stereo AND sustain up AND sustain down AND release samples. These take up all available dimensions and I need an extra tool like Virtuoso (which is almost finished) to add for example release triggered samples to a 8 layered instrument that has both sustain up and down samples.
There is no 16 layer DRY patch yet. I may add it later in an articulation file update.
The introductary offer will stand until Oct. and ships now. The final price has not been fixed yet but will be significantly higher. The cd is added to the PMI online shop last night.
