"Finally, the best unit in the DSM range, the DSM 32 x 4 128 Memory Programmable Module. The right hand controls on the restyled, 'hi-tech' unit are more or less identical to those on other DSM's, but don't be fooled - to accomodate the impressive memory functions of this unit, the circuitry has been completely redesigned. Sound generation is now digitally-controlled, and modulation has been added. The result - far crisper, cutting percussion sounds, and thanks to modulation, sophisticated F.M. metal textures. The sound capability is vast, ranging from convincing acoustic and electronic drums through crystal clear bells and effects sounds, to the most outlandish Doctor Who atmospherics.

And this power is supplemented by the '32's memory capacity. 128 separate sounds (and it can come up with at least 100 really different ones) can be stored in the machine's battery-backed RAM, arranged in 4 separate Memories of 4 Banks of 8 locations. (4 x 4 x 8 = 128): any location can be identified by a three-character code, i.e. 1A5, 4D3. Step through Memories, Banks and Locations via the momentary-make front-panel pushbuttons, or the corresponding rear panel footswitches. Current position is displayed by LEDs for each of the Memories, Banks and Locations.

Hit Manual to activate front-panel sound controls, Store to put the resulting din in the currently displayed location. Easy! As before, the footswitch functions are chainable, allowing you to step Memories, Banks and Locations individually or collectively, from a single controlling footswitch, pad, or trigger. Use this 'live' and a typical five-drum kit would come dear (£1500!) but it's as a 'drum expander' that the DSM 32 really come into its own, since the controlling unit (in our case, the Programmer 8) can advance the memories at every beat.

Assuming that you don't want more than two sounds at any one time a pair of '32's are capable of simulating a whole kit, and then some.

This unit, as a powerful (if pricey) supplement to existing acoustic or electronic kits, or to drum machines, will sell and sell. One gripe, though - there's no off-board storage. So don't overwrite your favourite sounds."
