”A new generation of modules has been produced to further increase the versatility of the SDS 7. In these modules, the analog section has been replaced with a second digital section, there are separate envelopes for each digital sound as well as a third for the noise generator.

The second sample has a programmable threshold control which allows for second sample to sound at a pre-determined dynamic from the pad, and the click circuit has been re-designed to accent the start of the digital sound, I.E. The ‘click’ part of a bass drum. So for the first time the two distinct parts of a sampled drum sound are controllable. Combined with the filter controls and separate ‘bend’ controls for each sample. This module is the most versatile yet, and places Simmons once again at the fore of multi sample synthesis for percussion.”

“Primarily designed to offer the SDS 7 owner the flexibility of the multi sampled approach for the SDS 9 bass and snare drum, the modules can of course be used for any sampled sounds.”
