System Architecture
Documenting complex Eurorack systems or outboard hardware routing usually involves taking blurry smartphone photos or scribbling in notebooks. Recalling a specific modulation matrix weeks later becomes a frustrating process of reverse-engineering your own work.
This matrix provides a structured digital canvas. It uses standard DOM manipulation combined with SVG bezier curves to simulate physical patch cables. You can map out control voltage (CV) paths, gate triggers, and audio routing between oscillators, VCAs, and filters.
Once your signal flow is mapped, click export to generate a clean, high-resolution PDF schematic suitable for archiving alongside your session files.
What is an Analog Patch Matrix?
If you have ever seen a classic modular synthesizer, you probably remember the confusing mess of cables connecting different modules together. An analog patch matrix is essentially a digital version of that. It lets you route audio signals and control voltages to different places without needing a single physical cable.
You can use it to send the output of an oscillator into a filter, or use a low-frequency oscillator to control the pitch of your synth. The matrix grid makes it super easy to see exactly what is connected to what.
How to use the matrix
To make a connection, all you have to do is click on the grid where the row and column intersect. The rows usually represent your inputs or sources, and the columns represent your outputs or destinations. You can also adjust how much of the signal gets sent by changing the depth value.
Frequently Asked Questions
Is this tool for beginners?
It can look a bit overwhelming at first glance, but once you understand that it is just a grid for connecting inputs to outputs, it is actually a lot easier to read than a bunch of tangled cables.
What do the rows and columns represent?
Generally, the rows on the left side are your signal sources (like an oscillator or an LFO), and the columns across the top are your destinations (like a filter cutoff or pitch control).
Can I route one input to multiple outputs?
Yes. That is the massive advantage of a matrix over physical cables. You can send a single LFO to modulate the filter, the pitch, and the volume all at the exact same time.
