Sascha Haber – Northern Light Modular

1. Favorite knob or fader or switch on a piece of gear and why?

That one is easy… the knobs on my Tegeler Audio Manufaktur Schwerkraftmaschine.

Tegeler Audio Manufaktur Schwerkraftmaschine

I don’t have much outboard gear, but the Tegeler gear is simply outstanding.

They spend a good amount of practical engineering on those motorised pots and switches and seeing them turn while using the plugin is just magic.

And then you touch them during a session and they do not resist, but instead write the automation…

Wonderful german engineering 🙂

2. What bit of music gear are you particularly proud of?

That is my TTSH/1601 combo… the piece of gear that started my soldering career i would say.
I always dreamt of owning and playing with an ARP 2600, and 6 or 7 years back there was no re-issues like today.

But then I hear about this swedish project that was around for a while and ordered a kit from Jon. Little did I knew what it takes to build an instrument! It took like 3 months and occupied most of the living room space all the time.

But there I started to invest in tools like a proper DMM, my first real soldering iron and a scope. I actually managed to finish the project, got it fully working and learned so much in the process.

So I started the Facebook group called TTSH and at some point I did a group buy and talked Behringer into selling us a few thousand fader caps.

3. How do you see your gear in the landscape of music?

Very much as accessories to existing Buchla systems… like Akrapovic makes racing exhausts for Ducati, we make expansions for 4U systems.

When we started Northern Light Modular both Marc and I had a small DIY system.

Well, mine grew at that time as I built each and every kit that i could get my hands on and after a year I had a massive 24U system blinking at me.

But then we looked at things like the Ornaments and Crime, Temps Util or the offerings by Mutable Instruments at the time and thought, that kind of stuff is missing in the 4U world.

And instead of cross patching Euro to 4U we got in contact with Max, and Patrick and of course Emelie and looked into collaborations to port them into 4U.

The 2OC was our first project and at that time in 2017 very much a Euro module behind a 4U panel.

It took another year or two to adapt all the software to work properly in the 1,2V range, revert negative voltages and show proper values on the displays.

But it was a great time, 3D printers allowed us to experiment with front panels and making your own PCBs was exotic and fun.

4. What music has inspired you to produce this gear?

I am a sucker for Berlin synth school…Tangerine Dream etc.
The O_c is in my opinion the best multi tool one can add to a rack, even if it takes a bit of learning .

But once you figured out how to cascade the quantizer playing variations of simple shift register notes, it plays generative music that is not just random noise.
And I like that a lot.

5. Most surprising tip or trick or technique that you’ve discovered about your gear?

Haha… the stuff other people do with my gear compared to what I intended it to be used for always amazes me.

Like, we build this massive 3 voice oscillator, spend countless hours to make it track 8 octaves and FM in sync with each other.

Sounds like angels singing and then someone comes and cross modulates the FM with the sync and all hell breaks loose.

So I am just watching and standing in awe, one part of me wants to yank out the cables and the others is like, that is super impressive, bro.

6. How did you get into music gear making?

Well, after that TTSH adventure, diverse EuroRack modules that came and went i stumbled upon the 4U crowd and how few options they had.

So we talked to Émelie Gillet (Mutable Instruments) and Max Stadler (Ornaments & Crime, Temps, Utile) about porting some of their designs and they were very helpful sharing and helping us up on the horse.

My lovely girlfriend Katrine, who built many of the SMD designs we have now, also is a wizard with the 3D printer and so we could prototype our new modules very quickly.

Like a great danish philosopher once said : 
Life in plastic, it’s fantastic  🙂


7. How do you most often start a new piece of gear? Where do the ideas come from?

Necessity I want to say, but that’s not quite true.

More often it is actually artists airing out ideas, pointing me to existing gear, or just imagining things.

Though the latest thing we’re making, was born from an idea to have a multi effect that works without any cables.
I have had a handfull of different guitar pedals and it really gets out of hand at some point with power and audio and midi cables.

So I wanted to build something that works straight in the Music Easel and can use its modulation.

We made a Kickstarter to found the project, I learned to program with Max/MSP at Notam/Oslo  over winter and BLAM!… we had a multi effect.

8. How do you know when a piece of gear is finished?

Is it ever ?

Most of our modules evolve constantly… either we fix small things here and there or sometimes, when they need a bigger change we made a V2 or V3 like with the Ornaments.
The latest version has input and output attenuators and LEDs indicate the actual level produced…
I think no other O-c in the market has that… and the software still works with that added hardware part.

Every year we also do special edition that we auction off for a good cause, and last year we made one for the international trans fund.

Ekkoflok – Flok… fl*k.. f¤*k.. ^¤*\

1. Favourite knob/fader/switch on a piece of gear and why?

NP-Elektroakustik faders

I generally have a thing for long faders on old analog gear, my favorites being a large Neumann stereo fader and the faders on old NP-Elektroakustik gear (used by Danish Broadcasting)… It’s just so satisfying to move (and even just to look at) them.

Neumann stereo faders

However I must admit that these faders do not really get much use at the moment because I have to “solder them up” – I guess this is the curse of DIY’ing stuff… It’s easy to end up with the soldering iron as your main instrument and a pile of unused electronic junk… But it can also lead you to explore new and surprising sounds and techniques.

NP-Elektroakustik analog mixer

For a more “fun” choice I’d choose the “gear lever” found on a lot of old Scandinavian reel to reel tape recorders. These old machines are largely mechanic and so the transport mechanism is all handled mechanically. I find it oddly satisfying to operate these levers controlling the mechanics

Scandinavian reel to reel tape recorders

For a purely synth-oriented (or functional) viewpoint I’d probably choose the rate knob on the Serge Smooth and Stepped Function Generator (SSG) (when used as a sample and hold) – it is possible to go in and out of perodic and (seemingly) nonperiodic patterns just by fine tuning the knob. This is a way of generating “melodic content” that I have used a lot.

2. Do you have an ‘almost’ perfect bit of kit? What would you change?

Ekkoflok’s homebuilt modular

That has to be my homebuilt modular….. which is ever changing… I started building it from scratch back in 2012. At first I planned on building 40(!) modules… That was before I realized the amount of work needed, I guess.
I also found that my plans/ needs for the instrument changed all the time is I learned more about synthesis and developed my own techniques.

Today I do most of my performances on a part of my modular system. I have found that it actually helps me to not bring to much modular gear, as I find you can do a lot with just a handful of modules. Sometimes I’ve brought to much gear for a live set and felt like I only scratched the surface of the sonic possibilities. When I bring a smaller setup I force myself to think creatively and push the modular to the limit.

3. What setup do you bring on holiday/tour/commute etc.?

I recently bought my first synth (that is – the first one I didn’t build myself) – a Korg Volca FM. It’s so small that can easily fit in even a small bag pack.
I’ve often brought a minimal modular setup, a portable recorder and sometimes just my laptop. Last summer I wanted to get ”away from work” so I only brought my Sound Devices recorder, microphones and headphones. That way I didn’t end up working as if I were still at home (and at the same time it made me long to get home to all the patch cables).

4. What software do you wish was hardware and vice versa?

Cecilia5 – a great tool for sound exploration. I would love to have that in a dedicated box or maybe as an app.

VCV-rack aka. the Gateway drug

With the rise of VCV-rack I think it kind of fulfilled a lot of desire for virtual versions of my modular. Still would love to see a software version of the Neutron Sound Orgone Accumulator along with more esoteric synths like Serge and Buchla. However I still think the physicality is one of my hardware modular’s main strengths. I feel that a few modules can take me a long way.

5. Is there anything you regret selling… or regret buying?

I have a couple of boxes filled with half- (or less) populated PCBs (printed circuit boards). Thinking of all those half finished projects makes me a bit sad.
I sold two (broken) 4-track recorders during corona…. Still sometimes asking myself whether I should have tried harder to fix them, since they were sold very quickly. However I still have two functioning ones… How many 4-tracks do one need??

6. What gear has inspired you to produce the most music?

That must be my homebuilt modular synth. Since 2012 when I devoted myself to that project it has been the pivotal point of my career. It has taught me so much about music and sound. However I rarely approach it with a ”now I’m gonna make a track”, it’s more of an explorative process that often leads me to discover new sounds or form the basis of a new track idea.
My album Lydlandskaber (2017) was made entirely with one-takes and the modular as the center piece, whereas my new album Mosaik is made out of many layers of modular sounds, field recordings, prepared instruments and vocal work.
Actually it took me a long time to figure out how to use the thousands of recordings on my hard drive.
In more recent year I have begun to work more and more with tape, which I also find very inspiring. It feels like it gives me a lot without me doing anything, it sort of has it’s own life. In the digital domain I often find myself wanting to colour things up a bit or a lack of character.

7. If you had to start over, what would you get first?

Well, when I started making music in the 00’s I was using plugins exclusively the first years – it made me dream (and drool) of a synthesizer wall… And back then hardware synthesizers (and especially modular gear) wasn’t very accessible. Since I grew up in a family of artists there wasn’t a lot of money, but lot’s of creativity so it seemed obvious to me that I should build my own synthesizer.

Today there are a LOT of options when it comes to analog synths… So maybe I’d just buy something. However I think it is important to take your time and dedicate yourself to your instrument which might be harder to do if you are constantly hunting for the ”next big thing”. I think a good place to start would be something like a Minibrute, which has all the essentials and then build (or buy) a rack of things to expand on the functionality. And then a 4-track and some tape-loops. I think it is important to try what it feels like to make music without a computer, personally it resulted in me creating an entirely different style of music and it helped me realize how I wanted to use the computer creatively.

PD in dark mode

For example I like working with Pure Data which is kind of modular-modular synthesizer in the sense that it is easy to create your own modules in contrast to VCV-rack which is rather an emulation of a hardware modular. Since I’ve spent so much time with modulars it feels very natural to think in terms of modules and patch cables. I also use Ardour for tracking and mixing but I prefer creating music without being tied to a daw and then use the DAW later in the process for refining and over dubbing.

8. What’s the most annoying piece of gear you have, that you just can’t live without?

Sound Devices MixPre 6

Probably used to be my Zoom H4n which has been upgraded to a Sound Devices MixPre6 – although I love many aspects of it, there are a few annoying things – for example it is so power hungry that I have to use a usb power bank which makes it a bit clumsy.

9. Most surprising tip/trick/technique that you’ve discovered about a bit of kit?

The Serge Dual Universal Slope Generator can double as a clock divider. The Serge DUSG is probably my all time favorite module, it can do so many things, sort of a chameleon module that you can (patch-) program to do (almost) anything. The Make Noise Maths is inspired by this module and is quite similar.

Serge Dual Universal Slope Generator

But back to the question – what I like to do is to have a master clock sending pulses to both sections of the DUSG (used as envelope) using the outputs to control a vca or vcf and then modulating the decay time of the to DUSGs. This can result in some very complex and ever changing rhythms because the envelope doesn’t start over until the cycle is completed. Another favorite of mine is to use the outputs of the DUSG to “ping” resonant filters. That way you can make a percussive sound without needing a dedicated oscillator and vca.

Valdemar Kristensen- aka. EkkoFlok

Where are you from?

I’m born in Næstved but my father lived in Vesterbro, Copenhagen so I guess I have experienced both the boring suburban life and the (at that time) rough atmosphere of Vesterbro with junkies and sex workers on every corner.

How did you get into music?

I think I was around 12 years old when I opened Cubase (sx3) the first time. I was playing drums at the time (and a bit of guitar). I think I heard about Cubase in some TV-show (Boogielisten???) and then I “borrowed” a copy of it. I clearly remember how overwhelmed I was by the complexity of the software, but at the same time fascinated by all the possibilities. At the time I was playing in a band (and very enthusiastic about it) and I thought the other band members were not dedicated enough. So it was a joyful moment, when I found out I could be my own one-man-band with the help of a computer and a DAW. While my friends where playing World of Warcraft I was jamming out in my basement room.

What still drives you to make music?

The music is free space where I can disappear into another dimension and completely forget about place and time.

How do you most often start a new track?

I probably spend the most time on “sound exploration” – looking for something new or exciting (to me). I then try to record (on my Mixpre or tape) as soon as possible.
I have a huge library of sounds from these sessions that I try to combine to form compositions.

How do you know when a track is finished?

It has to feel finished. When I had a more DAW-based workflow it was quite hard to tell when to stop; there is always something to change. Since I changed to working more with one-takes it is much easier I think, and the process feels more immediate

Show us your current studio

I often find myself creating music on the floor. I think it can be very inspiring to build up a new “mini-studio” with a limited amount of tools/ instruments.

Best creative advice that you’ve ever heard?

Probably “do it yourself”… I think this was a recurring theme in my childhood – that I could learn how to do things myself, be it playing the drums, drawing or building a synthesizer.

Gemini Horror – Hot Ambient Mess

1. Favourite knob/fader/switch on a piece of gear and why?

DIY varispeed knob on a walkman cassette

This is my favorite knob, there is something about making something yourself and peeking behind the curtain that is so magical.

2. Do you have an ‘almost’ perfect bit of kit? What would you change?

TC Electronic Flashback

I always go back to this delay, it’s simple and effective and has room to evolve with the toneprint stuff, although I haven’t messed with that yet. I wish the looper had more options, but I think the “X4” one has wayyy more looper options.

3. What setup do you bring on holiday/tour/commute etc.?

iPad with Mood iOS Model D app and cassette tape

Vacation? Holiday? What are those lol? When we’re able to travel again, I’ll probably do something simple like an ipad and a cassette recorder. There’s a lot of untapped power in the ipad world that needs to be explored.

4. What software do you wish was hardware and vice versa?

I guess I wish ableton had more specific controllers, like an operator specific physical controller. I know push offers some control but it would be cool to have all the settings at your fingertips. Honestly though we’ve entered the age where software is like 95% there in my opinion, VST’s and modelers are good enough for me 🙂

5. Is there anything you regret selling… or regret buying?

Korg Volca Modular

I regret buying the volca modular, if you don’t have any modular this is a cool synth to see if you’re interested and there’s some great sounds in this box, but overall I never clicked with it. I would have rather gotten another volca fm or maybe a module.

6. What gear has inspired you to produce the most music?

Telecaster guitar

Hands down the guitar, acoustic or electric. It’s the instrument I learned music on and it will always be my number one!

7. If you had to start over, what would you get first?

I would do it just how I started, a guitar, a DAW, a mic or 2. I think a DAW should be the centerpiece of every musician’s setup along with their “main” instrument.

8. What’s the most annoying piece of gear you have, that you just can’t live without?

Nothing really annoys me that much honestly. I don’t really like mixing/mastering and that is always a big road block between me and releasing music. I should just hire someone to do that stuff but I don’t have the funds to justify it.

9. Most surprising tip/trick/technique that you’ve discovered about a bit of gear?

Ableton Live MaxForLive Randomizer

My FAVORITE thing right now is a maxforlive randomizer. I use it on everything, hardware, software, effects, arps, everything. I found myself in a rut and I was creating similar stuff too often but the randomizer has opened the floodgates on what is possible with gear. I think generally we underestimate the power that things have. Like the randomizer on a microkorg will give you a lifetime supply of sounds and effects that will consistently surprise you.

Where are you from?


How did you get into music?

I took classical guitar lessons in middle and high school along with piano, music theory, and orchestra.

What still drives you to make music?

I’m not sure right now, I think it’s something I have to do to maintain myself and it’s my creative outlet. Without it I think I might die from boredom.

How do you most often start a new track?

There is no one way. Sometimes it’s something I can’t stop playing on guitar and other times it’s an instagram post I liked.

How do you know when a track is finished?

Hahah, tracks are never finished, but they have to leave you at some point.
