“Schweren Herzens trenne ich mich von dem kultigen Drumcomputer “Drumtraks” von Sequential Circuits INC und hoffe, dass er in gute Hände gelangt. Er wird euch treue Dienste leisten.” Link
“The unit functions very well; however, there are a couple of minor issues to note. A piece of one of the side wood panels has broken off (see pictures). The panel itself is still attached and the unit is totally structurally sound. Also, the two screws on the front (side) panel are missing, so you can easily open the unit up to see the circuitry inside (see attached pic); please note this and be careful when pickup up the unit. The DrumTraks can get hot near the power supply during extended/very long periods of continuous operation. I have no idea why this happens, but it doesn’t seem to affect the sound or function of the unit in a major way. The only thing is that the pattern storage memory does clear itself out once in a while. Not sure why this happens or if it’s related to the unit getting hot. Therefore, I’d recommend controlling this unit via external MIDI so that you get the classic sounds without relying on the classic memory function (that’s how I use it).” Link
“I am selling my Sequential Circuits Drum Traks that I got from a guy that was Prince’s Tech in the 80′s.And he said this drum traks was actually used by Prince in Paisley Park Studios.

“8 Bit Kultklassiker as den 80er Jahren mit Midi
Infos auch im Netz oder auf meiner Homepage www()beatboxer()de Zur Auktion steht das dort beschriebene Gerät. Anleitung ist mit dabei. Die Schrauben an der Geräte Front sind wohl nicht mehr Original, da man die Sound EProms durch öffnen des Gerätes tauschen kann. Auf dem Bass Drum Chip steht Linn Bass Drum. Hab leider keine Bin Files für SQC Sound Eproms im Netz gefunden. Wer welche hat, bitte melden, ich kann sie kopieren und brennen.
2.4.2013: Jetzt hab ich Bin Files und auch das SQC Bass Drum gebrannt. Unterscheidet sich auch nur durch 1 Bit vom Linn Bass Drum, sowas 
Dafür gibt es zu dem Linn EProm noch 2x Percussion: AGoGo/Bell und Wood Block/African Bell, sowie die Snare 23/Side EProms mit dazu.
Gerät weißt Gebrauchsspuren auf, dem Alter entsprechend. Auf den Fotos sind leider ein paar Lichtreflexe bei den Reglern. Das sind keine Kratzer oder Lackschäden! Ein Kratzer ist über der Bass Drum Taste.
Witzig der Peace Spruch auf der Platine, die durch die Entwickler angebracht wurden. Angeblich läuft im Bestriebssystem auch eine Mantra Schleife mit ab. Für Esoteriker ist dieses Gerät ein unbedingtes Muss 
8 Bit Knall und Crusty Sounds aus den 80er Jahren, stimmbar und mittels einstellbaren Accent 2 stufig Dynamisch spielbar. Ansonsten weiß ja jeder, was das Gerät kann, der es haben will!
Funkioniert einwandfrei. Siehe auch meine anderen Auktionen” Link
“Here we have the Sequential Circuits Drumtraks 400. This drum machine is in excellent condition and is functioning 100%. I believe all the PROMS are original except the bass drum, which is a Digisound replacement. The battery is good and shows no signs of leakage or corrosion. Interestingly, the Serial Number is 0005, indicating it is the fifth Drumtraks ever made! Cool! Includes version 0.5 of the OS ROM, which makes it ready to integrate into your midi studio/setup without a hitch. This machine is great for interfacing analog and midi gear through simultaneous midi and analog clock outputs.” Link
“Here’s the sought-after Tom drum machine that works! I plugged it in with headphones and everything lit up and worked as you would expect. Excellent condition, with very minor surface scratches, but no damage or dents. This is the one you’ve been waiting for. Power adapter in the picture is included. Plug it in and go. ” Link
“1984 Sequential Circuits Drumtraks in good working condition. OS is version 3, all EPROMS seem to be the original. All lights, knobs, outputs, buttons, and MIDI connections function as they should. Best of all, the battery seems to have been replaced because it holds everything in memory when powered off then on.” Link

” I am selling my classic mid-80s Sequential Circuits DrumTraks drum machine. It’s a real classic as used by Prince in the 80s and still heavily used today by many artists. My second child is due in a few weeks and I need the space. I’m gutted to sell it as it’s great fun! You can adjust the volume and tuning of each voice and it syncs to midi clock.
As you will see from the photos, it’s not in mint condition but it’s not too bad for its age. The wood panels are remarkably good. The main cosmetic issue is some scratches to the front panel. Other than these cosmetic issues, the unit is in full working order. ” Link
“From vintage synth explorer : ” The drumtraks is a very programable classic drum machine from the eighties. While it electronic drum kit sounds may not be as popular as the TR909 or TR 808, the drumtraks exceeds them with superior editing capabilities”. Midi plus outputs for clock signal.
Please note that one of the tempo keys sometimes sticks a little. Other then that no problems. You get what you put into this machine with each drum having the optional output it’s endless what you can do.” Link

” Up for grabs is a PARTIALLY WORKING Sequential Circuits Drumtraks vintage drum machine. The unit makes sound but it does NOT record nor does the metronome work. The “slower” tempo button seems to be stuck, the “faster” button sticks occasionally. The unit DOES make sound both through an amplifier/ headphones. The snare button only fires when the accent button is held, one of the toms will occasionally double fire. The original seller I purchased this from said all the sounds worked flawlessly through MIDI but I did not test this. He also didn’t let me know that the unit only partially functioned and I don’t have the time or resources to restore it. I had a brief communication with a company that restores these devices but didn’t have the time or desire to have them take a look at it. I’d be happy to point the winner in the right direction of a complete restoration!
The chassis itself has some bumps and bruises – there is scratching on the face as well as the bottom. One of the feet had broken in two and was superglued back together before being screwed back on. The side panels have scrapes and nicks. Please look at the photos for the most complete description of the exact condition it is in physically.” Link

“Legendärer Drumcomputer mit MIDI.
Dieses Gerät hat den dicken analogen Drum-Sound der ersten Hälfte der 80er, die neue Emulatoren immer versuchen zu kopieren, aber nie ganz hinkriegen.
Komplett mit original BDA auf Deutsch (selten!).
Der Drumcomputer ist in einem guten gebrauchten, funktionsfähigem Zustand. Aber bitte beachten, dass es sich um Alt-Elektronik handelt, die nicht eben gerade generalüberholt wurde. ‘ Link
“Verkaufe ein Sequential Circuits DrumTraks von 1984.
Die Drummachine ist in einem gebrauchten Zustand. Der Tuning Poti fehlt (wie auf dem Bild zu sehen ist) funktioniert aber noch.
Fast alles funktioniert noch Einwandfrei bis auf eine der Tasten (Ride) die funktioniert manchmal nicht richtig muss wohl der Kontakt gereinigt werden.
Die Sounds können alle über Midi noch abgespielt werden.
Die Sounds sind sehr “Old School” mässig und wurden damals unter anderem von Prince benutzt.
Zusätzlich zu den Standard Sounds gibt es noch weitere Sounds oben drauf, die man auf Knopfdruck umschalten kann. (alternative BassDrum, Toms sowie jeweils ein anderer Sound für Cabassa und Cowbell Taste)
Die Programmierung gestaltet sich supereinfach und auf Wunsch kann ich dem Käufer das Manual per Mail schicken.
Wer auf Drumsound der 80er Jahre steht für den is dieses Teil ein Muss.” Link

“I have a sequential drumtraks that works, but is not without flaws. It is missing the cosmetic load button for the tape as noted by the picture. The button is cosmetic and the pad still works. Midi works good, and seems to be the best way to use this drum machine. The sequencer works, but I found it to be clunky so I used midi. You will probably need to download a manual to figure out how to operate the sequencer. I did not have triggering issues when used with a midi controller. I integrated it into ableton live and it worked great. The pads on the unit itself tend to double trigger. It may be a simple fix, but I did not investigate further. I upgraded the operating system to the latest 5.0. I have included the old operataing systems too as well as documentation on the operating systems. I also have a couple extra sound chips for your use. It originally had four crash chips, but this one only has three. This does not hinder operation, just makes the decay time shorter. It is also missing one of the ride chips and in that case it makes a shorter ride sound. These chips can be found on ebay and wine country. All other chips are in good working order sound like they should. each drum pad makes sound and has a voice chip inside. I had the battery replaced in 2011. Individual outputs work good. All its issues aside, it has a great sound. With a midi controller it can be fun to use the individual outputs with a mixer and some effects. Definitely has that early 80′s Prince sound. Manuals can be found online and you will need one to get midi working correctly. This auction includes the drum traks unit, 2 extra operating systems, and 2 extra sound chips(ride 4 & timbale). ” Link

“Sequential Circuits Drumtraks drum machine. In great condition. To the extent I’ve used it, works with no issues whatsoever (including MIDI). A few cosmetic scuffs that you can see in the photos, but these are minor. Any questions, please feel free to ask.” Link
” This Sequential Circuits DrumTraks drum machine is in good working condition and good cosmetic condition. Please see the detailed pics which are of the actual unit itself. All jacks, buttons and knobs work well. This was recently being used in my smoke and pet free studio. You won’t be disappointed with the cosmetics as this looks really clean. The printing is still bright and clean. There are a couple of small nics but nothing major. I did want to mention that there are a couple spots around the lower lefthand knobs and the Metronome volume knob where the black paint on the metal chasis appears to have been worn off. I think someone who owned it previously must have really pushed the knobs into the machine as they turned and so turning the knobs must have worn off the paint in those spots. The wood end cheeks as you can see are in good shape considering their age.” Link
“This is a gently used vintage Sequential Circuits Inc. DrumTracks drum machine in working condition. The LED lights and displays are working, I plugged this into an amplifier and got great drum sounds from the various channels, the master volume and individual volumes worked fine. I am unable to test it any further but assume it to be ready to go.” Link
“The all time Vintage Classic drum machine: Drumtraks, by Sequential Circuits. Designed in the 80s by the coolest company after Daddy Moog, Drumtraks features all those fantastic Prince-style noises and a few Linn Drum sounds I’ve put in myself. If you’re techie, you’ll know all about this machine already.
I’ve owned this one since 1987, but have to part with her. No space left in the house.
She’s been well used, as you can see from the photos, but still works – up to a point. The ‘Memory Full’ sign comes on when I try to write new beats, and I know the memory’s not full. Also, the traditional Bass drum sound has mysteriously morphed to a Dub Step sound. So she’s gonna need a visit to the Synth Doctor.
The drum sounds are changed by changing the chips, which pop out easily from their sockets. Comes with a couple of spare chips. And the owner operator’s manual!” Link
