From the website:
Our library of sound samples has been specially recorded by members of the Philharmonia, and is free to use.
It includes all standard orchestral instruments, as well as guitar, mandolin, banjo, and a vast array of different percussion instruments.
The sound samples can be used in spi.
If somebody can give a tutorial on how to convert these sound samples to synth so that usage is easier in spi.
