Welcome Francis,
I have the #4 board in my at home 7K and it is full of wonderful orchestral sounds - strings, woodwinds and special effects. If I need a sound for my play on location 7K, I just look at what has been done to the board file dupe it and save it in sound memory for transfer to the location 7K.
If you enjoy orchestral arrangements, you will find #4 useful.
