I've uploaded a free demo version of Signature Piano, the new Kontakt-format C7 from K-Sounds. Two download formats are available: zip (large download size, greatest compatibility) and self-extracting rar (smaller download size, may require software that recognizes rar files to unpack correctly on a Mac).
To download as a zip file, right-click here and select "Save As" or "Save Target As." The download file is 476Mb, and it unpacks to about 765Mb. Use your computer's unzipping functions to unpack the file.
To download as a self-extracting rar file, right-click here and select "Save As" or "Save Target As." The download file is 172Mb, and it unpacks to about 765Mb. To unpack, double-click the file. In the window that appears, choose where you want everything to go, and click Install.
Demo features and limitations:
Notes in the middle two octaves of the keyboard (an octave in either direction from middle C) are like the full version - full unlooped decay up to 20 seconds. Notes outside that range fade-out after about 1 second. All release resonance samples, hammer noises, and damper noises are provided from the full version. All samples are 16-bit, not 24-bit like the full version. The script-based interface is fully functional.
Like the full version, you need to have Kontakt 2.2 or higher. The new, free Kontakt Player 3.5 will also load these sounds, but the player puts time limitations on use.
Edit: Like the demo, the full version is available in both zip and rar formats. Both are included when you order the download version of Signature Piano.
Enjoy the demo!
