Since over a year now I am sample content provider for Hammond-Suzuki, the successor of the legendary organ manufacturer. As the instruments like the SK series allow loading sample instruments into the onboard flash-rom every owner of these organs can download new sounds from the Hammond-Suzuki websites (USA, Europe, Germany).
The growing list of sample instruments covers famous synthesizer legends, orchestral instruments, power stacks and more.
More details and the actual download list on the Hammond-Suzuki Europe website here
