Could you build this?
No This is a physical hardware project involving electronic schematic design, microcontroller programming, custom PCB fabrication, and 3D CAD modeling.
What it would actually take: Building a custom hardware synth requires CAD design for 3D printed enclosures, custom PCB schematic and layout design in KiCad, component sourcing, surface-mount soldering, and embedded C/C++ firmware to read analog potentiometers and drive a SAM2695 synthesis chip and I2C/SPI OLED display.
Discussion
20 comments analyzed.
Competitors mentioned: Teenage Engineering PO series (PO12, PO14, PO16, PO24, PO28, PO32, PO33, PO35), Garageband
Concerns raised: Interface is confusing and difficult to use despite good visual design, Fixed clicks don't work with variable scale intervals (major, minor, chromatic, pentatonic), Unclear if plastic materials are safe for children, Soft tooling lacks flexibility for design changes and breaks frequently
Feature requests: Open-source/DIY build option with 3D printer files and component list, Community Discord for builders and parents working on electronics projects

Same idea, different domain
Nobody's really built a hardware & robotics tool for Horizontal yet.
