Hello! I just received my Chromaplane from a reseller (thanks, tarriffs!) and I've got a strange issue.

From startup, the "external input" light (the bottom left hole) is always lit, and when I hover a pickup over it, I hear a slightly quieter unison of what appears to be all of the coils in the unit. I have tested this by messing with the tuning while holding over the bottom left coil, and I can hear the oscillators changing tune.

Is this some kind of undocumented secret feature? Could there be something wrong with my unit? It was a B-Stock unit from Perfect Circuit, so maybe it was a pre-production unit?

Thanks!

I'm having a hard time troubleshooting my Koma Komplex. I am unable to get any MIDI in or out of the device to attempt an upgrade to fix the issue. The quantizers don't seem to do anything to the CV Out on any of the sequencers. I have successfully updated all sequencers to v3.1. 

I've tried emailing support a few times the past couple months since I've received the sequencer and have not gotten a response. I'm pretty disappointed if this is the quality of hardware and service I'm getting for a $2000 piece of equipment.

Hi,
I'm experiencing a strange issue with my Komplex after about 30–40 minutes of use.

• CV pitch slowly drifts (around 20–30 cents).
  
• Occasionally one sequencer skips a step without any reset signal.
  
• MIDI clock also becomes slightly unstable at the same time.
  
• Rebooting the Komplex temporarily fixes everything.
  

Hi. Im having problems with the digital delay on my field kit fx 
1. I’m hearing the delayed signal at the output, but not the original input signal.
2. When the delay time is turned above 12 O’clock it emits a series of high pitched beeps which become faster as the time knob is increased. This happens even when there is no input.
Can anyone help? Thanks

Hi. Used to own one of these years ago, and had to sell it. I am trying to buy one from a very nice Reverb seller, who is trying to update the firmware for me.

Wondering if anyone has an idea here. (hoping that he will also post here, and potentially provide more details).

He says that he went through the procedure and that it was successful, but when he checks the firmware on the machine, it still shows the old version. (I don't know which version that is - i suppose that might be relevant. i don't know if it was 3.1 or an earlier one). 

I suspect that there is nothing wrong with the machine, but that there is simply a missing step, or perhaps this is normal.

I really want to buy this, so i hope someone knows what the issue might be. Thanks.

Hi,

I recently received my 'Field Kit' and Field Kit FX' and I don't think I ever had this much fun exploring new gear before.

I did have a little question though, since the Strom Mobile is currently out of stock I purchased these two adapters to power the Field Kits through a powerbank...

I am not expecting this to be a problem but wanted to check with some more knowledgeable people to make sure I don't damage anything. It seems unlikely but I'd rather be sure as I love these things way too much to take the risk.

Thanks in advance,

Hey there,

First time customer here. I submitted an order for a Komplex sequencer in late March and we're now in May and I'm yet to hear from anyone at Koma. I understand that this is a small company so I was just curious what the typical time is between order to the point where you might expect to hear back from someone. (we're not talking about time to delivery - just the time it would take for someone to send out information about the expected wait time) 

Since this is my first contact I'd be happy to hear from anyone with information about how this generally works :).

Thanks,
Tomas

Hi,

Is it possible to power the Strom+ with a powerbank for a portable system?
I am planning a 7U 84HP Flightcase.

Power Consumption of tthe case should be max.
+12V @ 1250mA
-12V @  450mA
5V  @  0mA

I am not really sure what powerbank to use.
There are 15V Powerbanks, but I believe they only support up to 3,6A and I believe Strom+ needs 4,6A?

Maybe there is someone who is running Strom+ already from a Powerbank and can point me in the right direction?

Thanks,

Hello everyone,

I'm looking to use Arduino boards with my field kit sensor section (and other things) and on the Koma website it implies the best way to power an Arduino is with the dc motor interface

"The maximum output-voltage is about 8v. It provides enough current to power an Arduino"

I'm just wondering if it is possible to power an Arduino board from the 5v output and ground output of the sensor section and then use more complex sensors with the Arduino and then just output the sensor data from the Arduino and input to the field kit signal input?

I'd like to use the dc motor and an arduino at the same time if possible for a couple of ideas i have and just wanted to know if the plan was viable or I'd have to rethink slightly.

Hi, many of us have experienced the Divisions knob loosing functionality when updating the OS on older Koma Komplex Sequencers.

I got these instructions from Christian at Koma with the permission to share them on this forum.


Boot into the Testsoftware
• To boot into the Testsoftware hold the following buttons while powering the machine:
• STEP - GLIDE - SSP - GATE
• This will bring you to the "Color Setting Menu" (check the manual if you're interested in changing your colors)
But there is a hidden division calibration too! To enter the correct menu for calibrating your divisions press and hold MODE, then press the first step button (step 1) on all four sequencers. This will bring up the "light show" that we use for testing LEDs. Now press and hold MODE and press step 6 on all four sequencers. Now you're in the Division calibration mode for each sequencer. To set them do the following:

1. Turn the `Divisions` knob to counter-clockwise, until it can't move anymore (to the :32 division).
2. Press the left most `Step` button (Step 1). The LED of the slider above should light up / move to that position.
3. Turn the `Divisions` knob one position further clock-wise. Press the `Step` button to right of the last one that you clicked (now Step 2). The LED of the slider above should light up. (This saves the position of the knob.)
4. Repeat steps 3 until all the knob doesn't move anymore. (You are doing it right, if the LEDs light up from left to right.)
5. Press the `One-Shot Mode` button of the sequencer you just calibrated to save the configuration to the EEPROM, so it is saved after the unit has been turned off. Now all the LEDs in the row should light up. Wait until only one LED lights up again.
6. Move the `Divisions` knob. The LEDs should now move with the position of that knob. Check if every position of the knob has one LED light up. If not, repeat steps 1 to 5.

You need to repeat this for every sequencer (sorry). And then your divisions should work again. Sorry for the hassle. But really it doesn't take very long and will make your Divisions more stable than ever before.

that's it - hopefully this thread can help you if you get stuck like me :)
