I’ve heard you sometimes also fix gear, can I bring my stuff over?

It’s correct that we fix gear sometimes, but this is only on the special Fix-It-Days, we try to host 3 or 4 of those per year and everybody who would like to drop by can come by our office with their broken piece of gear. We will try to fix it for you free of charge, while you drink a beer, have a chat, play with a modular synthesizer, our pedals, the kommander and all the other stuff that is lying around in our office.

The Rules:

  1. You have to come in person with your piece of broken gear.
  2. Please contact us in advance at support@koma-elektronik.com with an overview of the problems so we can assess the situation.
  3. When we cannot fix it, we will try to point you in the direction of somebody who can.
  4. We usually get 7 – 10 people over on one afternoon and we want to help them all, so when you want you analogue synth completely checked, it’s maybe better to look for somebody who is specialized at that and has the time to do it right.
  5. Fun: it is supposed to be fun, so please come and drink our beer and talk with other enthusiasts, we do it to meet all of you!

PLEASE NOTE: We only accept gear for fixing on these special days. Please do not contact us about fixing gear when we did not announce a new Fix-It-Day, since we are very busy with building and giving support for our own products! Thanks in advance and hopefully see you soon on a Fix-It-Day!

KOMMANDER Questions (6)

I can’t fit four 3.5 mm (minijack) cables in all the outputs of the KOMMANDER, what to do?

When you want to use both CV and Gate outputs, so 4 outputs in a row, we recommend Doepfer a-100c cables. They fit beautifully, 100% guaranteed. In Europe? Get Doepfer cables at our dealer Schneiders Laden! In North America? Take a look at the page of our dealer Analogue Haven. We are aware that we are not giving you as a user many options here, but we really needed make sure the output jacks would all fit in the handheld enclosure we had planned… You win some, you lose some…

Does the KOMMANDER interfere with other light sources in my room?

Normally spoken: no, in rare cases some halogen lamps or a very bright sun shining directly on the sensor can produce unwanted side-effects though, so whenever you notice strange behavior of your CV output try to trace down the ‘bad’ lamp or move the KOMMANDER out of the sunlight. When it comes to normal stage light, we tested the KOMMANDER many times in a concert setting and everything behaved like it should, so no worries before you step on stage, big strobe light effects were not in the test budget though, so if you have experience with that kind of power in combination with your KOMMANDER, please let us know!

Can I use my KOMMANDER with a “pedaltank”-like powersupply?

Yes! Make sure the maximum output is 9V / 500 mA per KOMMANDER with a centre negative tip. We advice to use the KOMMANDER with the original KOMA Elektronik PSU.

Can I use my KOMMANDER in combination with a banana jack system?

Yes, make sure that you have right extension cables and give it a go! (make sure that the output voltages match with the input voltages of your synth!) A customer told us he uses his  banana jack system with two KOMMANDERS, that are  powered up with the Harley Benton Powerplant and it provides enough power for both and the earth for the banana jack system.

Do you also offer factory modifications for the pedals?


We can tweak and change our pedals a lot and love to do it!

How to get a modified unit, you’ll find here:

A FACTORY MODIFICATION BEFORE YOU PURCHASED THE UNIT?

First of all: get in touch with us! Let us know which product you want to buy and what you would like to see modified. We will let you know what the possibilities are and what the price / time estimation will be. When you confirm the order, we’ll send you a link for the payment and you will receive your product by mail as soon as the payment is in and we worked our magic. We will modify your unit by hand, so it will take longer than when you order a standard product, but we will keep you up to date about the process!

A FACTORY MODIFICATION AFTER I PURCHASED THE UNIT?

Get in touch with us by email, let us know who you are, what you would like to see modified and we will check if its possible. When we can do it, we will send you a price and time estimation. When you shipped the pedal back to our workspace and you made the payment for the modifications, we will get to work. As soon as the modification is finished we’ll send it back to you. Do not ship your equipment to KOMA Elektronik until you have received an RMA number.

Do your pedals have easter eggs?



That’s the fun part of our job! So: of course! Check the documentation coming with the pedal to figure some of them out (others we’ll keep secret)!

Pedal Questions (3)

My FT201 has an extra hole on the backpanel, is this normal?

This is absolutely normal; the second run of FT201′s has a extra hole in the back which is used by us in the final setting and testing process before we send the pedal out to the customers.

My manual says my KOMA pedal is shipped with a PSU, a manual and a bag of pots, but I can’t find the bag?

In the boxes of the first run of pedals we added a little baggy with 4 (FT201) or 5 (BD101) trimmer shafts to put in the trimpots on the back cover of the pedals. For the second run of pedals we decided that it would be easier for customers to just use a small flat screwdriver instead, this so the setting of the attenuators would stay the same when the pedal is transported.

In the new manuals we wrote about this change, but it seems that a few of the old manuals were sent out to our dealers by mistake.

Do your pedals come with a power supply?



All KOMA pedals sold within North America, Japan and Europe come with a center negative 9V DC linear regulated 500mA power supply.  We recommend you to use your pedal ONLY with this adapter, since we can’t assure the quality of your sound otherwise.

RH301 Questions (7)

I have my DAW as a master clock controlling the RH301 but the tempo is fluctuating. What can I do?

Many sequencer programs and other music software will send all available MIDI information on all available MIDI channels at the same time which can sometimes lead to unstable MIDI clock information because of soundcard or hardware limitations. Try to disable unnecessary MIDI information and choose the right MIDI channel to send your data to the RH301. This will improve the accuracy of your MIDI clock signal going into the RH301.

My LFO will randomly reset while syncing to external clock signals?

Please check your MIDI/DIN Sync/analog clock connections. Many problems arise from cheap or broken cables. Also be sure that you don’t accidentally modulate your LFO rate via a CV signal attached to LFO SPEED and keep in mind that if you do so, the LFO needs one bar to adjust to the new tempo.

I connected my DAW to the RH301 via MIDI but the pedal doesn’t seem to start?

Firstly, make sure that you set the master clock sync source to EXT and make sure that your DAW is sending the correct MIDI signals. The RH301 expects a MIDI clock signal, not a MIDI time code. Furthermore, your DAW should send a start signal whenever you hit play. Sometimes it can happen that programs only send a start signal in the beginning of a song, not every time when you hit Play – for example in Ableton Live you should try to set “MIDI Clock Type” to “Pattern” in the MIDI Sync preferences tab. Your RH301 also won’t start to sync to MIDI when there is a cable plugged into the EXT. CLOCK jack on the patch bay – even if no clock signal is present at that input.

Also, check your MIDI cables. A large percentage of problems with MIDI sync are arising from cheap or broken MIDI cables. If you have the opportunity, try different MIDI cables.

Some of my equipment is starting to hum when I attach a MIDI cable?

This can happen in some setups, mostly involving USB MIDI interfaces or other equipment with a USB MIDI connection (sound cards, hardware MIDI controllers, etc.). Try to prevent ground loops and check your MIDI connections – did we already mention that a lot of problems come from cheap or broken MIDI cables?

When I connect my drum machine to the DIN OUT of the RH301 it starts and stops randomly?

Please check the DIN cable that you use. Like with MIDI, most of the problems stem from defective or wrong DIN cables. Make sure that all the pins on the cable are connected from one end to the other.With some MIDI cables it can happen that only the pins used for MIDI are actually connected through the cable. MIDI and DIN use the same cable and plug but not the same pins on that cable.

I patch my sensor to the CV inputs and it doesn’t seem to change anything?

Make sure you use the correct PSU (9V, 500mA, center polarity negative) for the sensor to work correctly. Have a look at the back of the pedal and check if your CV attenuators are in the right setting. Furthermore keep in mind that the incoming CV signal is added to the corresponding knob on the front panel (LFO RATE and LFO SYMMETRY) and you won’t hear your changes if they are set too high.

I set my RH301 to FREE mode / EXT. mode and sync to an external clock signal but my DAW/synthesizer/drum machine doesn’t start playing?

The RH301 converts incoming start / stop signals from MIDI to DIN Sync. If, however, you miss those start/stop signals because they were sent before you plugged in the cable or none are sent at all you have to create them yourself by pressing the large black pushbutton.

SVF201 Questions (5)

What is the best Gain setting for a clean signal?

The Input Attenuator / Gain control defines the amplitude of the signal that will travel into the filter. At a counter-clockwise (CCW) position there will be no signal going into the module at all, at around 9 o’ clock the signal will be at unity gain and at full clockwise (CW) position the signal will be boosted by about +6dB.

Can I use the SVF-201 with my +5V rail?

If you have a +5V power supply on your bus board rails and you want to use it with the KOMA Elektronik SVF-201 then you can change the second jumper setting from ‘Onboard’ to ‘Bus’. Don’t worry, the two +5V rails can never be connected together, regardless of how you place the jumper.

What are the specifications of the Mix Out CV input?

The Mix Out is a special output of the SVF-201 which contains all three of the outputs (LP, BP and HP). You can sweep continuously through these three outputs with a control voltage signal from 0 – 5V. The diagram below shows the corresponding loudness curves of the filter characteristics in correlation with the CV input. Low pass appears at 0.25V to 2.25V, pure bandpass between 2.25V and 2.75V and from 2.75V to 4.75 you’ll get high pass as an output signal. All outputs crossfade into each other.

The Mix Output has more internal gain than the three different single outputs, so signals taken from this output will have more overdrive / distortion than their respective partners. The signal levels themselves are identical though.

What should I do when I want to switch of the white light around the Cutoff knob?

If you don’t like the white light around the Cutoff knob simply take out the jumper above ‘LED Corona’ (and try not to lose it!).

Can I mod my SVF-201 so I can control the back light via CV?

Yes! Please check out this post.

And yes, you WILL void your warranty (so make sure you know what you are doing!)
