hsballina / 16n

Sixteen faders, a Teensy, MIDI over USB and jack, CV out, and I2C out. Phew.

16n

Once upon a time, Sean Hellfritsch and Brian Crabtree made a faderbank.

16n is the revised version of that object: it is open-source and ready for you to make, modify, or hack.

It is currently at hardware version 1.34, firmware version 2.1.0.

Repository contents

• firmware is the Teensy source code.
• electronics is schematics and gerber files for the PCB.
• panel is SVG/DXF files for top and bottom panels.
• build is build documentation.
• browser_test is a legacy test webpage to let you test your 16n. As of 16n 2.0.0, the editor should be your point of call for debugging your 16n.

Each directory has further README files in for you to read.

Your first point of call for documentation, however, should be the Github Wiki.

16n Details

• 16 60mm faders
• sixteen CCs over USB-midi
• sixten CCs over minijack midi (with switch to swap between standards)
• sixteen 0-5V CV output jacks, one per channel.
• I2C: monome-style I2C protocol over TRS (tip is SDA, ring is SCL), works with Monome Teletype; also, I2C MASTER mode, works with monome Ansible, ER-301, TXo, etc (may require firmware patching or modification to connected device).

Power from 5V micro-usb into Teensy on left-hand side, or from your computer.

Toggle switch allows you to swap between 'Arturia/Novation' (tip is current source) and 'Korg/Makenoise' (ring is current source) standards; board is labelled such.
