Home - 16n-faderbank/16n GitHub Wiki

16n is a bank of faders for controlling electronic musical instruments. It emits MIDI, control voltage (CV), and I2C data. 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. You can download latest versions from the releases page, where you'll find firmware releases, as well as zipfiles of panels and hardware at the 1.34 release.

The menu on the right --> has links to the user guide, BOM, and more.

16n Details

• 16 60mm faders
• sixteen CCs over USB-midi
• sixteen 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.

Give us a picture, then

BOM

Available on Octopart; a CSV version is in electronics/bom-csv.csv

Most parts you can get from eg. Mouser. I recommend buying PJ-302 jacks from Thonk as an alternative to the more expensive CUI parts. If in doubt, 1% 0805 resistors of any manufacturer will do; caps are X7R with appropriate voltage tolerance.
