Teenage Engineering Eurorack, POM-400 Matrix Kits & Talking to Aliens with a Steiner Masters Touch

Talking to Aliens video upload by Dave Vondle

This is a bit of a triple post. Dave Vondle of wrote in to let me know the final 9 units of the Ghielmetti Pin Matrix Kit for the Teenage Engineering POM-400, previously posted here, have been completed. It's featured in the video above and in a post by Teenage Engineering on converting their Pocket Operator Modules (POM) to eurorack.

That said, first the description for the video above:

"Figured out how to communicate to extraterrestrial organisms.

The Calmset 3 connected to my brain is generating the frequencies - and the Masters Touch is taking breath, bite, and touch into the Teenage Engineering POM-400 (with my matrix kit attached). Breath controls the amplitude and bite/touch modify filter parameters. This all runs through the VOCU tape echo."

See here for some additional posts featuring the Masters Touch including pics. You can also find some info on Patchman Music here.

Second, info on the final batch of Matrix Kits from

"Over a year ago I created a bolt-on kit to turn a Teenage Engineering Pocket Modular 400 into a matrix synth like the EMS Synthi. Instead of using cables to patch outputs from one module into inputs of another, you use the supplied pins to connect a row (output) to the corresponding column (input).

I have completed the final batch of 9 kits, as the manufacturer of the matrices recently went out of business. Teenage engineering just wrote a blog post featuring the kit, so I figured it would be a good time to get these last kits out there.

More info about the kit:

The matrix itself was made in Switzerland by the established patchbay company, Ghielmetti, and the kit simply bolts onto the back of the POM-400 modules with the supplied hardware - there is no soldering required. Once bolted on, it enables you to make 100% of all the patches you could otherwise make using cables, with the added benefit of having virtually no restrictions on the number of available outputs and inputs for each module. Patch cables can still be used in conjunction with the matrix for interfacing the system with external modules and running sound out from the device.

I thought you folks might be interested! For more details and to place an order go to

Bonus Video - Here’s me when I patched a Steiner Master’s Voice into the POM-400, with the kit installed:" [above]

Third: eurorack conversions for Teenage Engineering's Pocket Operator Modules (and euro racking Pocket Operators):

via Teenage Engineering: eurorack is a very common system format when it comes to modular synths. there are tons of modules and manufacturers on the market and the pocket operator modular series is eurorack compatible. this means any POM system can be used together with any other module, from any other brand. while the pocket rack format is slightly smaller than eurorack, you only need some minor tweaks to fit your pocket operator modules in your eurorack system.

here are a few ways to 'eurorackify' your pocket operator modulars and pocket operators, plus a bonus mod to really expand the capabilities of your POM-400.

eurorack front panels for POM
the two companies and jklmnt have joined forces and created custom eurorack front panels for the complete range of modules available in the pocket operator modular POM-400 and POM-170. pick your favorite module and mount that in your existing eurorack system, or create a complete replica of an entire system. the various panels range from 6 hp width, up to 18 hp.

power adapters
they've also made a convenient power adapter that easily converts the power connector from pocket rack to eurorack. no soldering is required and everything above is available through the oddvolt webstore.

pokit for POM-16 by grayscale
the company grayscale makes modules and stylish eurorack front panels for a lot of products. their pokit is a eurorack conversion kit for the POM-16 keyboard. the front panel has a matte black finish and is 42 hp wide. the kit even comes with matching gray official knobs. this is a great option for enabling your system with the 4-channel sequencer, arpeggiator and keyboard that is the POM-16.

pocket operators and eurorack
the usually hand-held regular pocket operators can also be used in a eurorack system. this could for instance be a great way to create a portable and powerful grab-and-go live performance instrument, or to have pocket operators tightly and neatly integrated into your studio setup. here are two examples of how to mount pocket operators in a eurorack case.

Additional SYNTH CITY Listings

"A high water mark for glassine pads, premier brass stabs, and surprisingly present basses, the Roland Juno 106 is well deserving of it's status as a classic synthesizer. All voices have been refurbished, this is a fully working specimen, with all sliders and pots cleaned and working wonderfully.

This model was a Japanese market 100v unit. We performed the following actions for smooth North America operation...

-Replaced hard wired 100vac plug with IEC Jack and chassis grounded.
-Replaced original 100vac transformer with new 120vac transformer.
-Replaced original battery with socket for cr3032 and new battery.

Very good condition overall, includes hard case as photo'd.

"As you can see from the second picture there is a little Bend to the left side of the rack. You could bend it back. There are a few scratches on the unit including one on the top and it stands out more due to the silver medal underneath the black paint, a black permanent marker would make it less visible. It is missing one of the knobs. As for the functioning everything seems to turn."

Demo ONE - Deep Techno & Electronica - Circuit Rhythm Sample Pack by A Force Truly Evil

video upload by Isotonik Studios

"Deep Techno & Electronica is a truly dark, deep and introspective musical force, full of structure and style. Robotic, mechanical and soulful, always looking to the future.

The sound of Deep Techno & Electronica saturated with tape delays, heavy reverbs, ice cold atmospheres, and a strong Dub Techno influence.


64 drum and percussion sounds that cover the territory you'd expect, deep kicks and techy snare drums, classic analog drum machine sounds, 909 and 808 clones, plus a selection of electronic and acoustic percussion.

A selection of 32 synth waveforms

to turn Circuit Rhythm into a synthesiser. With shaping tools like filters, envelope slope and distortion we can obtain multiple variations of each wave. Raw sonic material like basic sawtooth, sine waves and pulses, sub basses, hard-edged digital sounds, along with more complex waveforms like atmospheres, pads, textures and synth chords.

In short, a well balanced sonic arsenal for anyone working in any genre of Techno or electronic music territory.

8 One shot bass samples.

16 One shot Dub chords.

8 Loop samples: Four drum loops and four synth loops. All can be adjusted for pitch and tempo using the slice function. Loops can be sliced and diced to use individual notes or isolated drum hits, or to have multiple instruments in a single track.

32 high quality sessions/project covering from the organic and precise patterns of Deep Techno to the darkest and most atmospheric Dub, passing through the roots and impulses of Detroit to end up in evolutionary and minimalist electronica.

Some sessions include several scenes.

Custom grid effects template for dynamic pattern variations.

All samples except loops are in the key of C.

Wav files are provided so that you can use the samples with your favourite DAW.
