Hi there,
sorry for this question, I know it's silly, but i'd rather ask before I do something sillier.
I own both the FK and the FK FX, and I've been planing for a long time to moubt them in my rack.
I've done it with my FK, and it was really easy.
My concern is abut the FK FX : on the original frontpanel, there are some little plastic rods to guide the light from the coloured leds to the surface of the frontpanel.
So I suppose I should take these rods and put them on the eurorack frontpanel.
My question is : is there a good way tu pull the rods out from the former panel and to put them backin the holes of the eurorack panel.
I mean : without breaking them. :)
I thank you in advance

I have a field kit Fx and some days ago I inadvertently plugged in another 9V adapter with reversed polarity...  and since then it hasn't turned on anymore.
I've had it for years so it's out of warranty, but I can try to repair it myself.
I would need to know which piece is the one that may have broken (9v to 12V converter???) and if it may be where it is located.
It works with eurorack power so must be something in the DC power.
Thanks a lot,

I have a problem with the sequencer of my FT 201 filter, which is discontinued and out of warranty. Ive just received an email from Koma to say they will only repair products that are within warranty, which is a real shame as I really hope to get this fixed...

Basically, the filter itself is working fine, but the step sequencer is not moving through the sequence at all, no matter whether its on or off or what speed it is on. If I flick the dial from off to 2 to 10, the light will just randomly jump to another step and then just sit there until I switch the sequencer off and then back on again, when it will do the same thing, jump somewhere else, ad infinitum. 

I would love to get this sorted as I have got a lot of use out of this little box!

Any ideas?

Hey all, I'm having some troubles with my Field Kit sensors from the Sensor Pack A.

They don't appear to be working correctly, or only work occasionally and I'm wondering if the issue is with my Field Kit or the sensors or if I'm missing something?

The only sensors that seem to function (if at all) are the ball sensor and button. When plugged into the SWITCH IN, I have gotten the ball switch to for example trigger the DC Driver, however it only works about 20% of the times I have tried. I plug it in the identical way with the same settings and it doesn't work. I turn it off and turn it on again, sometimes it works, sometimes it doesn't. 

On the signal input, only the ball switch and the button switch have been able to work, and here again the ball switch only works on occasion. Everything else has no impact whatsoever. 

When plugging the connectors in I always make sure they're flush to the sensor and that the D5Gs are correctly aligned. 

Are there any common issues that could cause this? Am I doing something wrong or missing something?

WHAT WE DID??

Early October we teamed up with berlin-based Modular Gang founder Rachel Lyn. Together with her we created a beautiful limited edition of our Dual Discrete VCA module inspired by the aesthetics of vintage appliances and early electronic test equipment like the old control room tucked away in Berlin’s Kraftwerk building.
For the occasion we did for first time since common ground closing a workshop with a little party. (stay updated on social cause more are coming).

   


You can find the limited edition module here :)

Kassiopeia meets Osmium------------------
We've been busy with improving the circuitry of our upcoming motor / solenoid controlling device called Kassiopeia. During the summer we've had the honor of working together with Hildur Gudnadottir, Sam Slater and James Ginzburg from Osmium and develop and modify custom instruments with them for their gig on Unsound Festival in October. We've made ample use of the Kassiopeia prototypes for that occasion and Kassiopeia has now seen the stage light for the first time already!

Hi everyone,
Today, after putting my FX Kit back to the wooden case (changing jumpers) and accidentally plugged 12V adapter my FX Kit is partly broken.
The audio circuit (INPUT via GAIN to MASTER) works fine, but the 'digital' part of the FX does not respond. No lights, no sequence/envelope, no looper/shifter, etc.
Is there any way to try to reset it? I know, I know... this 12V is total FCKP. Too many wires on the desk :/ 
Please let me know about any check-out or recovery procedure I should perform to find out what I've actually done.
Greetings,
Piotr

On the Field Kit I repaired for free, 4 jacks are kaputt. Do you have maybe some spare parts in stock?
If not, could you please give me the reference where to find them.

The owner broke 3 of them previously. Not recommended to block them too tight.
Myself I broke one when I was unmounting the panel. The metal nut came off with the thread when I unscrewed it!

Hello folks, 
I am new here. I´ve just recently bought my FK and few days back finally got into trying it and I encountered a problem with my DC Interface and CV/Trigger in particular. I am actually not certain, if the problem is on my side or not. When I tried to use my solenoid and sync the DC with the LFO the red indicator did not show anything. But after a while my solenoid began to heat up, so I thought that maybe there is just problem with trigger, because when I plugged the LFO into the envelope follower, it seemed to work just fine. Could the problem be somewhere inside? Or maybe I did not take into account some factor or I am just stupid as hell. I tried to do it according to some video from youtube like step by step by it did not work anyway. 

Thanks for any tips

I tried to update my Komplex to 2.3 from 1.3. MIDI update over sysex worked fine, as did sequencer updates for A, B, and D, but sequencer C fails every time. There is not indication during the firmware update process that the update has failed, so during my first attempt I simply moved onto sequencer D which worked fine. 

When out of the boot loader mode sequencer C cannot be played; both start and stop are unlit. Lights on the individual steps for sequencer C are lit, but don't blink. Attempts to check the firmware version for sequencer C fail as well, but work for the other. 

When attempting to re-do the firmware update everything appears to progress as normal, but there is no two-blink confirmation at the end, and when rebooting sequencer C remains not operational. Just for kicks I tried flashing the firmware for A, B, and D onto C to see if anything would work, but none would take. 

When the pandemic first hit I was talking with Christian from Koma Elektronik over email, and his suggestion was to get my hands on an AVR programmer and try flashing the firmware directly on the chip, but then our studio had to close, we moved cities, and by the time we reopened and I finally was able to return to the problem it has been two years. 

So now I have an AVRISP mkII and am keen to get this piece of gear operational, but understandably the folks at Koma Elektronik are unable to provide support for things out of warranty. Does anyone here know how to do this direct flashing procedure?

Hiya KOMA!

I was referred to ya'll by a forum post when I was looking at trying to see if a standard for case to case interconnects existed and attempting to come up with one that might be a good starting point. My design used 4-pin XLRs. The power sources would have a female XLR and the power destinations a male. I was pondering unregulated DC and using linear PSUs to bring the voltages down to +- 12V (and optionally +5V but I kinda ignored that for now since it seems rather rare these days) or using standard +/- 12V and being mindful of cable distance and things due to voltage drop.

That's just what I came up with but then I saw ya'll have what appears to be a Molex style solution. My question was around if you would be willing to share the pinout and design with me and perhaps other folks in an effort to try and get a case to case (and power to case) interconnect standard?

I'm a small boutique case maker which I guess kinda makes us competitors but mine aren't nearly as nice as yours and I'm over in the US so I think we comfortably sit in different market segments perhaps! As a user of Eurorack though, the lack of modular cases has bothered me (I see yours are expandable which is fantastic!). Being able to start with a small enclosure and power supply, then extend to other enclosures (without having to get rid of the old one) and then upgrade the power solution as needed seems to me to be the spirit of modular yet I haven't really seen that? I think there's only one case maker that has any sort of case to case power interconnect (forgive me I don't remember the name, but it's one of the metal case makers).

Anyways just curious as to your thoughts! Sorry if this isn't the right place to ask. I couldn't find a direct contact us link to an email and thought this was better than hitting ya'll up on Instagram.
