SDS7 PWND BY THE 909

YouTube via MADRRRRR.

"Just playing around with my 'new' simmons sds7. The accent of the 909 works on the trigger too and gives random responses.

To bad the analog part of the bassdrum is a bit busted. Some pots react only at the end and one of the toms leaks noise when it set to zero.

But listen to those cem 3340's osc's, the lovely noise and those 8bit crushed & cut up sounds.

Can't find any clues on the filter but it's sweet ! if anyone got any clue about the filter please let me know. Also i would love to have service manuals but i think they're just not there anymore. If anybody got more cards or a 'full' working sds7 let me know too.

thanks to theo parrish for the groove inspiration and 123synthland for pointing at the sds7"

Simmons SDS-7 Vintage Drum Brain

via this auction

"Here’s a Simmons SDS7 Drum Brain made in St. Albans/Herts England in the early 80’s. The state of the art in electronic drums is the Simmons SDS7. The two major developments for this kit are its sound generating capabilities and its programmability. In terms of the sound, it is the first drum synthesizer (electronic kit or drum computer) that uses digital chips and analog synthesis to provide ample control over fifteen different sound parameters for the drums and cymbals.

The SDS7 will store ninety-nine sounds per drum arranged as ninety-nine drum kits. Added to that is the programmable selector pad which gives access to any sixteen of the nine sets at the touch of a finger. I still say that it is the only electronic drum brain out there that can come close to the sound of the SDSV or SDS5 drum brain sound. The brain comes with NO pads or stands. This brain module is in excellent shape, all knobs are there and work. It has a buzz in the main output jack, but if you use the separate output for all channels there's no buzz.

The brain is almost fully loaded with ten modules. It has one Bass module, Bass 2 module one Snare module and Seven Tom modules. It also comes with a selector pad and one very rare vintage Memory Cassettes. These are extremely rare to my knowledge. I have only seen 3 on eBay in over 10 years. With the selector pad, 11, 12 ,15 and 16 work after it's been on for a some time. I never used it much. I know that it is a brain problem and not the selector pad. Number on the back is 72377.

This brain back in the day, with all it's loaded with, would have cost over $5000.00 dollars."

These models, by the nature of the technology, all have their own unique sound. And this one is definitely one of the cream of the crop.

The SDS7 was the Flagship of the original Simmons Electronic Drum Co. during the 80's. If you were a working drummer in the 80's, at any level, you had one of these, or wished you did. And if you were alive in the 80's and 90's, you have definitely heard one. Radio, TV, film soundtracks, etc...

Units like this don't come around every day. If you have ever wanted to own one of these, here's your chance. Doubt you'll find a cooler one in better working order. At least at this price."

"This is a quick demo of the Simmons MTM MIDI-Trigger-MIDI Signal Processor to show that it powers-on, the display works, buttons respond, etc."


via this auction

"For sale is an extremely rare Simmons MTM MIDI-Trigger-MIDI Signal Processor. Sync analog sequencers to MIDI! Control the SDS5!

The MTM was originally designed to control the SDS5 and SDS7 drum sound modules via MIDI or a sequencer. The unit has a number of great uses:

Control any sound source with a trigger-in from MIDI (Simmons SDS5, SDS7, other drum machines, even analog synthesizers)
Use the MIDI to trigger function to sync analog sequencers to MIDI & trigger various sequencer steps
Trigger MIDI devices from any audio source such as acoustic drums

Each signal can even be assigned to more than one MIDI note so whole cords could be triggered from a trigger source. All settings can be saved in one of up to 99 kits, just like the SDS7. The first 16 can be selected by the selector pad.

The unit is in great operational and physical shape (see photos) with some minor scratches commensurate with its age. It has been carefully stored for around 20 years in a climate controlled studio."

Boring Systematic Testing of Simmons SDS7 drum synth modules / insomnia cure

video upload by tonetweakers

"When you deal in vintage synths, attention to detail is essential, because every physical control or electronic component has the potential to be problematic. So we test our gear multiple times systematically over an extended period (with a long burn in test) to make sure we don’t overlook anything. Many of our so called competitors dont, which is why we have many loyal customers. In this video, we are systematically testing the last of 8 Simmons SDS7 modules. Its a boring but necessary process. Anyone familiar with sds7 editing knows that one push of the wrong button and the sound you were editing is erased and you’ve gotta start over. This only happened once while testing this set of modules. 😂

Thanks for watching!

Vintage 80's Simmons SDS7 Electronic Drum Synthesizer System LOADED w 12 Modules

via this auction

"This is a vintage Simmons SDS7 drum synthesizer with 12 modules. All 12 modules have EPROMS installed (please see the last 3 photos). it was removed from a recording studio, and put in storage for awhile. The system powers up, and seems to work as it should. I can press the 'Program' button, and all of the lights blink, allowing access to any of the individual parameters. I don't have any pads, so I can't test it further. Because of this, I'm selling it as-is for parts or repair. No returns."

Comes with everything shown. Tested and working great..."

"This unit has been meticulously refurbished and is working like new again and better than the rest.

In additional to sorting out any problems, we paid our tech to make this unit better than others on the market, a process that took a whopping 30 hours of skilled vintage synth tech time, plus parts costs.

Fully disassembled and cleaned inside and out
Replaced electrolytic capacitors in power supply
Resoldered regulators
Replaced all RAM (6166 x 10)
Installed new battery
Reloaded sounds off cartridge to first 80 kit banks
Cleaned all switch contacts
Replaced many IC sockets
There was a broken XLR connector, so we had to painstakingly remove the original rivets to remove the circuit board, replace the connector, and then Instal new rivets for 13 female XLR connectors - a time consuming PITA
Cleaned and lubed all pots

This unit is intentionally priced at what we believe to be top market value because of the big investment of time, love and money to make it better than others you may find.
