Hi all –

Does anyone here know what size of barrel plug the DC interface uses? It’s the same as the 9-volt power source jack, but that doesn’t help too much.

I have an OP-1, Monotribe and a Tascam digital recorder and have realised that the thing I like most is recording loops and mucking around with effects. I wondered if a Field Kit FX (and the extra kit with contact mics, etc.) would be a good way of both getting interesting things to sample in to the oP-1, but also a way of mixing things together.

I guess my concern is not having any other CV gear, is the Field Kit FX still usable? I like slooowly tweeeaking knooooobs, so am OK with hands on controls, which it seems to have. I’m thinking that it might tie everything together in a fun, noodly way.

Any opinions/experience gratefully recieved!

It’s definitely a fun way to get sounds in. One thing though is that the pots are all the skinny poles, which might not be much fun if you like slow, controlled knob tweaking. If you can deal with that though I bet you’ll find some interesting things to do with it.

Wrapping the pots in small rubber bands helps with the small size. Those wmd slider covers are pretty good as well for the fieldkit.

I’m not entirely sure, but these might fit the trimmers:

and these could work for the sliders:

Decided to go for it. Seems like it’ll be more fun than clicking a mouse and adjusting software.

I’m coming from a guitar background (acoustic / resonator / electric), but over the past few years my interests have quickly grown for ambient, electronic, and experimental music. Looking for a first step into this world, and I’m wondering for the koma field kit + field kit fx (and expansion packs) might be a good starting point.

Specifically, I’m curious if the field kits with a contact mic on acoustic guitar might offer interesting options for sound manipulation and feedback.

Has anyone tried this yet? Any advice or alternative suggestions?

(new to lines, so let me know if there is a better place to ask this question)

#217

Yes. You will enjoy it and make interesting sounds.

I use guitar extensively with my field kit(+ expansion and a good amount of pedals). It is a lovely piece of equipment, although a bit noisy(but I like that).

Filed Kit was my first eurorack module and I will never sell it.
I use it all the time for my drone ambient stuff. It’s really on the lowfi side but I love this sound.

@Gahlord @noiserock @felart thank you for the input! It seems like the field kit / field kit fx would be the right direction for me right now

Hello everyone, after a long night and morning thinking there is something wrong with my setup I think I found the culprit - and it seems to be the Field Kit FX - Is it just me or does it have an extremely annoying whine to it?

I currently have patch 43 setup (from the manual) which is the Shifted Delay - when i unplug everything the whine stops, im not sure how I didn’t notice before - perhaps because I was making more noisy stuff, where as im working on something more ambient now.

Has anyone had the same problem?

  • PS I just unplugged the output from the field kit fx and then noticed I could still hear the whine - for a second I thought i was going crazy, then noticed I could actually hear the whine coming from the unit itself! after unplugging and plugging it back in its still whining - surely something isn’t right here!?
#223

Are you using it with eurorack or standalone with its 9v psu? I have just been using mine which has been adapted for euro and there is no whine

#224

two things:

  • if you use this (euro)racked, whine could come from other modules. i installed an antumbra klik in my otherwise quiet case and immediately it all began whining - through the power rails.
  • if standalone then check if you use the power supply that came with it or is it some other adapter. small PSUs of the switching kind emit noise like that. you can hear whine on e.g. korg volca for the same reasons.
#225

I am using it stand alone with the 9v power supply provided by KOMA Elektronik themselves - then going into an adaptor so that it can fit into a UK plug (the adaptor was also provided by the company which I purchased the unit from)

I have tried using a different adaptor but I am still getting the same whine.

I have emailed the manufacturer so I will see what they have to say on the matter

Any help is much appreciated.

#226

I had the same noise with mine when I used it standalone. (similar to you, I didn’t notice it initially)

as soon, as I put it in my Eurorack, the noise disappeared - so definitely its the PSU.

have you tried using a USB battery pack and something like a Ripcord or the Koma Strom Mobile?
If I remove my KFK from the Eurorack, this is probably what I’ll do, not only should it get rid of the noise - but also will make it a nice portable solution.

#227

Its good to know I am not the only one!

I looked up the Strom mobile - what is a Ripcord? similar kind of principle as the Strom mobile?

I will consider this option, however I must say I feel a bit bitter spending more money to get the device to sound as you would expect after spending €200+

Going by this from Koma’s website - 9V centre negative, you could probably try a decent guitar pedal PSU and see what results you get with that. From the manual (“Another 50 ways”) the Fieldkit FX needs 600mA. Do double-check that centre-negative is indeed what is indicated on your PSU - you wouldn’t want to get that polarity wrong.

#229

If you record the output of the field kit (with no audio in) does the whine appear on the recording or it is strictly coming from the unit and going out in the air into your earholes? Is the noise from the unit or the power supply/wall wart? I have definitely heard a wall wart whine before, then fail shortly after and make a steady clicking noise. As others have suggested trying a different power supply might hopefully clear that up either way, but damn.
