<p>A friend showed me the <a href="https://electro-smith.com/products/daisy-seed">Daisy Seed</a>, an Arduino-compatible microcontroller made for developing audio equipment. With a little bit of motivation and absolutely no experience in either programming synthesisers or electronics in general, I quickly got my hands on one and started to toy around.</p>

<p>I split the PCB into four layers, separating power, ground, digital signals (switches and toggle), and analogue signals (potentiometers, audio out). I made some exceptions, such as for the waveform buttons, since they cross the playing key traces.</p>

<p>Alternatively, if your USB-C breakout board does not have CC pins exposed, there's a chance you could still connect pulldown resistors to make it compatible. On <a href="https://www.amazon.de/dp/B09FPZDDD9">this breakout board</a> I purchased on Amazon, I discovered that the third pin from the right exposes a CC connection. Wiring a resistor between this pin and ground enabled C-to-C functionality. If you want to test the functionality before soldering, you can hold a resistor between this pin and either the ground connector on the board or the USB port's outer shell, since that one's grounded as well.</p>

<p>Do keep in mind that this type of connector does not have mounting holes and requires either a more sophisticated mounting mechanism in the chassis, hot glue, or both. Also, soldering to this pin is insanely finicky, since it is VERY small, so I strongly recommend a breakout board such as <a href="https://www.reichelt.de/entwicklerboards-usb-typ-c-adapterboard-buchse-debo-usb-c-f-p376522.html">this one by Soldered</a> that exposes the CC pins.</p>
