I personally think that using mixers in Eurorack are mostly a waste of space and money. 99% of the time I only use them as summing mixers and that's nothing I need to spend 400+ bucks on when there are live (or studio) mixers outside of Eurorack since decades. It's a really low channel for buck rati...

Electrostatic, huh this indeed sounds like a hardware issue... Can you please send me an e-mail to christian@koma-elektronik.com as sometimes also seemingly simple questions can lead to a lot of follow-up questions. Thanks!

One nice trick the SVF-201 can do, is patching one of the outputs back into the input. If you play around with Cutoff and Resonance you can get pretty nice waveforms out of this filter! Put your melody CV into the Cutoff CV in then.

Uff, 10BPM is quite a lot. Which program/DAW are you using for sending the MIDI clock? If it is possible I would suggest that you turn off any unnecessary MIDI information being sent and send the clock alone. I know of many people solving a wonky Ableton MIDI clock (in any context) by turning off an...

Good pint, Dave. I was actually mainly looking for the part number as I forgot it. Google remembered it for me through this website... Did you ever use this IC?

If you're about to research more about hacking CV inputs into your modules, check out the H11F1 http://pdf.datasheetcatalog.com/datasheet/fairchild/H11F1.pdf It's kinda like a vactrol in a chip. Never used one myself though. I just look at the datasheet every few months and think "man, this chip is ...

Easiest would probaly be to simply put a diode in forward configuration into the CV input signal path. But it might also be nice to close an open filter...?

Thanks for all the kind words, guys. The slider is a 100K linear type. Works very well for CV and from our point of view also for audio and even as a on/off switch for any kind of signal as you can rali the slider from one side to the other quite quickly.

Thanks for the info. This sounds quite confusing... the mains power in your area shouldn't affect the wall wart adapter all too much, also because there is usually quite narrow tolerances on the "mains signal" (at least here in Germany...) to make sure appliances keep running at all times. So but wh...

Hey cgorsu , I am very sorry to hear about your problems with the Kommander. You say that you had the same behaviour with another Kommander that you also got from the same store? It can happen in some situations that certain lamps emit a modulated IR signal at the same frequency that the Kommander w...

Hello, machine. There is a trimmer on the backside to adjust the resonance ("Q") but it is set at the factory to the best results. It also affects the frequency response of the filter as a whole. It could be though that someone tampered with it before it got sold. When you look at the four trimmers ...

Well I guess the largest difference between a TV remote control and the Kommander is that the IR LEDs on the Kommander are running full power all the time whereas in your TV remote they literally only flash for miliseconds each time you press them.

It is possible to run the Kommander totally standalone but it eats quite a lot of current (around 500mA) so depending on your battery you would probably have less than one hour of running time and maximum something like two hours. Also, there is no space to fit in a 9V battery. But let me know if yo...

You basically only need your DC signal, a sufficient power supply (one that can deliver the 200mA), a transistor that can handle the 200mA (like the BC337 - can switch up to 800mA) and som good ol' trial'n'error ;) Also, you might google for "transistor emitter follower" or the such.

From a DIY point of view, working with FSRs (force sensing resistors) is quite easy. It is really just a resistor that changes its resistance when pressed. You can easily use them instead of potentiometers. Also you can use two pieces of that foam that ICs are often shipped in and put two copper cla...
