the US. After visiting and demoing the SDS-V to music stores in New York, Washington, Los Angeles and Chicago, he secured orders from them all. Manufacturing was ramped up quickly in time for the NAMM Music Expo in Chicago and after staging a series of demos featuring Bill Bruford, dozens more music store owners from all over the country signed up to this electronic revolution, and that expansion quickly established the Simmons name in the rest of the US. More models During the lifetime of the SDS-V, Simmons also produced a compact trigger unit about the size of a suitcase, containing seven small pads. Used in conjunction with the SDS-V brain, this allowed players to add Simmons sounds to an existing acoustic kit without incorporating a set of full-size pads. This unit was used extensively by New Order at the time. Also available at the same time was the SDS-6 drum sequencer, used to great effect by artists such as Howard Jones. Following the success of the SDS-V, Simmons expanded their range in 1984, with another modular rack-based brain called the SDS-7, which features digital sampling sounds on EPROM for the first time, expandable up to twelve modules, and redesigned pads, featuring a skin of rubber to make playing a little easier. The unit uses 8-bit samples and a programmable memory, but is prone to malfunctioning and loss of memory, making it unpopular in a live context. The same year, they also produced the cheaper analog-only SDS-8, which featured a single, non-expandable desktop-style brain with one unalterable factory preset and one custom user preset for each channel. The SDS-8 kit was supplied with four tom pads and a bass pad, using similar hardware to the earlier SDS-V, but in a more budget style, such as using jack leads instead of XLR connectors. The sounds were similar to the SDS-V, but, to the discerning ear, not up to the same quality. However, the kit has remained a popular alternative to the SDS-V for those seeking analogue Simmons sounds. Also available at the time were a number of smaller devices, such as an SDS-EPB E-PROM Blower to write samples onto the chips, a Digital ClapTrap unit, which is a digital clap sound device, a sound very popular in 1980s music. Simmons began to expand their product line with smaller kits and pads, including the SDS-1, which was a single pad with a
