The magic spell to get a video file encoded so that Erogenous Tones Structure can read it:
ffmpeg -i input.mp4 vcodec=mjpeg -q:v 3 -an -vf scale=640:480,yadif=3:1 output.mov
Best to get it into the right aspect ratio in video editing software before running ffmpeg. Also, at the 640x480 size you'll only get 400 frames worth of video clips to load. You can also do 320x240 and get 1600 frames.
Finally, use the system settings to configure which resolution you're using otherwise Structure won't be able to play the files.
That’s what a benjolin sounds like. It’s part of the charm.
When it’s bumming me out I run a tap from the pulse output, invert it, and blend it back in. Doesn’t truly “fix” it and sometimes sounds less fun. But it’s something I try now and then.
It doesn’t fully or accurately work, it just helps minimize the issue sometimes. It works because the undesired sound is the pulse. Copying and inverting the pulse will result in phase cancellation and make it quieter. If a person wants to get intense with it, they might want to be able to delay that pulse or the output signal to get a better match. It isn’t a perfect method and sometimes results in sounds that are less fun/phasey/hollow. But sometimes it results in fun sounds. YMMV.
You can see the trace that connects that pulse to the outputs on your board. I considered cutting mine but I don’t know enough about what I’m doing so I stopped worrying and learned to love the pulse.

Intro to modular series by Nicole Strobach.
- Introduction to Modular
- Audio Modifiers, Control Voltages and Passive Modules
- Patching, Audio Connectivity, Tips
This series is clear and covers the basics well. A perfect introduction for anyone trying to wrap their head around modular synthesis.
An opsec video.
Great introduction video to modular synthesis focusing on just a handful of basic modules (VCF, VCO, S&H, Gate/CV sequencer) presented by Václav Peloušek.
Feedback mixing with drums
You've probably seen/heard it before. This is a technique primarily for filthy filthy drums. It's derived from no-input. On a simple mixer (say, Bastl Dude or something like that), run your drums into the mixer, leave one input channel free with the gain all the way down. Mult the mixer output. Send one of the signals to your recorder/monitor/headphones and the other back into the mixer.
Very very slowly increase the gain on the feedback channel until wierd shit starts to happen. Keep tweaking with all the gain knobs until you have a sound you like.
Experimentation: put effects/filters/etc on the feedback loop, test out mutes to see what happens when sounds are removed because it can sometimes be very dramatic, try including a low pitch drone (in tune with your song, if you like) or an empty feedback-only channel in your mix along with your drums.
For anyone new to no-input mixing, here's a nice tutorial.
The Casper/Bastl Dark Matter is a eurorack module designed around the concept with a focus on percussion. Here's Peter Edwards explaining how it works.
