I own a 6 cards version of the SDS-V including the rare Cymbal card. Mine was pre-fitted with a DB15-contact on the empty panel when I bought it and I found out just recently that it was controllable through the Kenton line of midiconverters. I soldered a cable and after some fiddling around it works. No velocity sensitivity though (but Kenton do have a retro-fit available) but I don't really care. The contact was there and I already had two Kenton-converters which didn't make use of the Kadi-port so...

Now, I'm not just a happy SDS-V owner, I'm a happy SDS-V owner WITH ability to midi-control my darling!

The SDS V is a rackmount case that contains up to 7 monophonic analog synths, each on its own card. The case has a simple mixer and various ins and outs to trigger the synths from drum pads or audio, such as a click.

The synths are designed to make different kinds of analog drum sounds; they do this well but are pretty much useless for anything else, since there's no MIDI and I don't think the trigger ins can precisely vary pitch by voltage. In other words, you can't really play tunes on one of the synths.

There are different kinds of synth cards marked "bass," "snare," etc.. Each card has six knobs and is very flexible soundwise, but does not have standard parameters -- So for example, you have a knob for controlling noise generator level, but no way to set the filter cutoff. There are four memories for each card: One preset, one adjusted by the knobs, and two adjusted by little screws (!).

The low end, noise generation, and attack of the SDSV are great, and of course you can use the individual trigger ins to layer the sounds with your sample-based drum machine.

There are Simmons Vs around that have been modified by Vince Gutman; these work fine and were used by pros in the 80s. Note that the XLR pad inputs use a different wiring scheme than on some other instruments. Also note there is a tiny flat plastic piece for each card which sometimes shakes loose inside the case and causes the synth card not to work right.

The SDSV is all analog. The SDS7, intended as the top-of-the-line replacement for the SDSV, is part analog, part sampled sounds on EPROMS. There was a Simmons PROM-blower for making your own sounds. The MTM was a trigger-MIDI converter with extras for the Simmons drum modules.
