"1980s Amdek Rhythm Machine RMK-100 vintage drum machine in exceptional condition and in perfect working order. This early programmable drum machines was produced by Roland under the Amdek (later rebranded to Roland DG) banner from 1981-83, a subsidiary created exclusively to produce early computer monitors and small DIY music kits. The RMK-100 is particularly rare among analog drum machines due to its limited release and the fact that it was only produced in a kit form. It’s a step-write-style drum machine, designed to compete with the likes of the Boss DR-55.

The RMK-100 features Bass, Snare, and Open and Closed hat sounds, all distinctly warm and analog-sounding. Considering its era of production, The RMK-100 is an exceedingly versatile little machine; the Bass drum has internal trimmers for Level and Decay, and the Snare has a trimmer for Noise Level, allowing for excellent tonal sculpting capabilities. It’s a completely programmable machine, with 8 banks of 16-step pattern creation capability.

Controls are relatively simple: the four drum sounds are selected at the four-way “Sounds” switch, and the user inputs the sounds into the 16-step sequence through the two buttons (which also function as Start and Stop/Reset buttons when Play mode is engaged). A unique function of the RMK-100 is the “Filler” switch, which divides each 16-step sequence into 2, 4, or 8-step chunks and then cycles through the resultant sequences at an adjustable rate. The 8 banks are selected at the rotary bank on the right side of the unit, and there are individual knobs for Volume (also functioning as the Power switch), Accent, and Hihat Level."

Amdek DMK-100 Delay Machine

video upload by Geylo Follen

"In 1981 Roland establish a new Japanese division, called AMDEK (Analogue Music Digital Electronics Kits) Although Roland was based in Hamamatsu by the early '80s, Kakehashi established the AMDEK Corporation in Osaka. Their main product lines were small effects units and computer monitors manufactured for Roland.

This DMK100 delay model was released in 1981 sold as a DIY kit and can be built in a couple of hours using only a soldering iron, cutters and screwdrivers.

With delay times from 25 to 300 mS it can produce a wide range of echo, reverb and flanger effects and has a selection of input and output level and mix facilities with a lovely distorted sound if you crank the volume.

I modded my unit by adjusting the Intensity VR5 trimmer to get wild sounds and make the unit go to self oscillation."

"Extremely rare sound module from the 1980s

Basically an even rarer version of the Boss PC-2 Percussion Synth!

Crazy and very diverse analog synth sounds triggerable from the front pad

Excellent sound quality, comparable with the Japanese made Boss equipment of the same era as basically is the same equipment under a different name!

AMDEK was a division of Roland back in the early 1980s which specialized in monitors and other computer hardware but also did a nice line of electronics kits for self assembly which were derived from the Boss pedals available in the day

In 1983 AMDEK changed its name to Roland DG and dropped the entire line of music equipment to concentrate on computer products.

These are very difficult to find and don't come up for sale very often!.."

Roland AMDEK COMPU MUSIC CMU-800

via this auction
"Branded as 'Amdek' but is actual fact exactly the same as the Roland branded cmu-800

'Although Roland were based in Hamamatsu by the early '80s, Kakehashi established the AMDEK Corporation in Osaka. Their main product lines were small effects units and computer monitors manufactured for Roland (but not by Roland) in Taiwan. For a couple of years, the company proved to be surprisingly successful but, as competition mounted, Kakehashi decided not to compete with the large computer companies entering the market, and in 1983 he ceased supplying monitors, simultaneously discontinuing the effects units. But this was not the end for the company. Kakehashi renamed it the 'Roland DG Corporation', and then used it as a vehicle to release a range of the company's own computer and music peripherals.'"

DIY Boss PC-2 / Amdek PCK100 Percussion Synth

YouTube via hotchk155 | June 30, 2010

"see http://hotchk155.blogspot.com/2010/06... for more info

I wanted to build one of these bloopy analog percussion synths based on the schematic and a photo of the Amdek PCB.. and I think I just about succeeded with this DIY attempt.

I used to own a PC-2 so I can tell a couple of things about this one aren't quite right, like the sweep range. I needed to improvise with a BA6110 IC instead of the ultra rare BA662A and find an alternative to the centre-tapped sweep pot, but most components are true to the Amdek kit. See the link above for more info and the PCB template for etching.

Apologies for sound synch issues on the clip"

Anyone know more about this unit?

Update via Jared in the comments:
http://www.keyboardmuseum.com/ar/a/anat/filter.html

via Todd:
"Simply put - this company made devices purely to process incoming MIDI data ... This one would allow you to filter out MIDI "aftertouch", "pitchbend", "controller" data, etc. Not nearly as exciting as the name implies."

Amdek PCK-100 Percussion Synthesizer

Title link takes you to shots via this auction.
"The Amdek PCK-100 has been likened to the Boss PC-2 Percussion Synthesiser and looking at pictures of the PC-2 it would appear to be identical in terms of controls at least and even down the the choice of font! Hmmmmmm. I have read that Amdek was the user-kit division of Boss. However, I have to say I have never done a side by side comparison of the PC-2 and PCK-100 so cannot say here that they are identical in sound characteristics. However I can say that this unit is capable of creating some of the deepest BOOOOMs I have ever heard from any piece of kit. It is also capable of creating some very odd off-the-wall synth percussion sounds as wel as more traditional synth drum sounds and all using true analogue circuity. This is proper cool, no messing.

Included in this auction are the original assembly instructions / user manual, which present detailed instructions for modifications to the circuit to add extra oscillator waveforms or additional modulation possibilities. This unit has NOT been modified so if you are so inclined you can bend it either using the suggested modifications or by going off piste in true circuit bending style."
