"Awesome rare drum machine from Sequential Circuits. It has the Wine Country upgraded OS 0.4 which adds several MIDI related features. In excellent condition and fully working!"
via this auction "Operating System ROM DRUM 0.5 is installed, it offers OMNI and POLY modes over 16 MIDI channels, MIDI Pads-Out commands & velocity sensitivity via MIDI, tuning information sent & received via MIDI and the ability to synchronize to tape & transmit MIDI clocks. Best version when using Drumtraks as a drum machine for patterns (according to Wine Country Sequential). It comes with all of the original sound chips (sample eproms) installed and is totally stock (no mods)."

"Updated in 1997 by Wine Country Productions of San Jose, CA (run by former Sequential employees after Sequential was bought out by Yamaha) with an alternate TABLA chip in place of one of the toms."
"Batteria elettronica del 1982, prodotta in Giappone da Sequential Circuits Inc (Dave Smith) - Demo audio e uno sguardo dentro...
Tra le caratteristiche all'epoca più apprezzate, la possibilità di intonazione e la regolazione di volume per ogni singolo strumento (programmabile in step o realtime per ogni singola misura). Inoltre la funzione swing e la funzione accento conferivano alle tracce la possibilità di "umanizzare" la dinamica di ogni singolo suono. Infine, ideale anche in studio per le sue 6 uscite separate, che consentivano di processare esternamente e individualmente i gruppi di suoni. Una batteria elettronica che ancora oggi merita attenzione."

"Drum machine in 1982, produced in Japan by Sequential Circuits Inc (Dave Smith) - Demo audio and a look inside ...
Among the features most appreciated at the time, the possibility of tuning and volume control for each instrument (programmable in realtime or step for each measure). In addition, the swing function and the function gave emphasis to the tracks the chance to "humanize" the dynamics of each individual sound. Finally, an ideal studio for his six separate outputs, which allowed the external process and individual groups of sounds. A drum machine that still deserves attention.

"Sequential Drumtraks in extremely good condition. Cosmetically, the unit is very clean and well looked after - as seen by the clean boards. Bought from a recording studio approx 5 years ago and always kept in a smoke free environment, there are no issues such as crackles, misfiring or 'sticky' keys. This is a very reluctant sale and purely due to a change in circumstance. Please note: There is a slight discrepancy between left wooden cheek and metal chassis - as pictured, this has always been present and does not affect the unit in any way and appears to be a misalignment of the external screw."
YouTube via AnalogAudio1 "The Sequential (Circuits) TOM is a great drum machine - similar to the SCI Drumtraks. Also it could be the little brother of the Studio 440. It has a decent MIDI implementation and understands MIDI SysEx. The TOM's memory contains 8 samples; inserting a sound cartridge, you can have 7 additional samples. The crispy 8-bit samples sound great. In this video you will hear the following cartridges: "basic percussion", "special effects", "latin percussion" and "contemporary"."
This is one of my favourite vintage drum machines.
The Sequential (Circuits) TOM is a great digital drum machine made in USA - similar to the SCI Drumtraks. It has a decent MIDI implementation. The TOM's has 8 samples built in; inserting a sound cartridge, you can have 7 additional samples. A shame, that it does not have individual outputs.
The crispy 8-bit samples sound great. The built in sequencer has a 'tight' groove, it grooves like hell!
I don't mean the 'shuffle' function (there is none). It has a very tight timing!"
"Sequential Circuits Tom drummachine + rare Contemporary expansion soundcard with extra drums (electronic set Kick, Snare, Tom, Lazer 1, Scratch, Splash) + original manuals (both user and MIDI guide) + original power supply 220V/50Hz (European). Excellent EPROM drum sound, improved Drumtraks with extra features (reverse, stack, etc.)."
via the seller: "It's in great shape, but cosmetically and working order. It was fully serviced earlier this year by Wine Country Sequential, a company made of the same people who built this unit 30 years ago, and to prove that I will include a copy of the receipt. Since it came back to me from Wine Country it has been kept in a smoke free home studio.
But the thing that sets this particular auction apart is a set of very rare extra sound chips. I've included twenty six extra chips that you can easily swap out with the included original set to create some amazing programs. Includes conga, bomb toms, alter bass, african drum, clang, clave/bell, car horn/dog bark (lol), and many more. There are some I can't even find info about online. Some labels are faded and I can't even tell what they are, it'll be yours to discover. I tried almost all of these and they worked great, but there are some I didn't even get to myself. Swapping the chips is easy, you just undo two screws on the front, pop the original out and the new one in. I'm an electronics simpleton and I can do it in 10 seconds with just a screwdriver."
