XVI 16 Channel Fader Bank with CV, I2C, and MIDI

Regular price $255.00

THIS IS A PREORDER, ITEM SHIPS 1 September 2020

 

XVI is a 16 channel, 44hp control surface for Eurorack

Features:

  • Long throw LED 60mm faders
  • 0-5V, 0-10V, -5 to +5V CV ranges per channel
  • Fully analog CV outputs
  • I2C communications as leader or follower 
  • Fully buffered I2C communication
  • I2C mode and addressing easily set by hardware switches. No coding needed
  • MIDI header for one output channel on the back of the device
  • I2C, MIDI, and CV can be used simultaneously
  • Arduino codebase for further customization of midi output/I2C data
  • Available expander with additional midi and i2c outs
  • Dual Colored LEDs.  Red/Green . Red/Blue, Blue/Pink

Dont forget to order an I2C/MIDI cable if you need one!

Expander Available which adds 3 Midi outputs, 3 I2C ports

 

44HP Width, 20mm Depth
Current Draw: +12V 50 mA, -12V 80 mA

 

Basic Usage instructions:

Front:

Voltage Select switches:  Independent for each channel. Does NOT affect MIDI/I2C data

Slider LED color: To change the LED color, simply remove the cap and rotate the square LED 180s.  Do NOT force the LED back in, it should slide in easily, may require wiggling.

 

Rear:

Power Header: Standard 10pin power cable, there is NO polarity for this connection.  It can be connected either way

 

 

MIDI Out Header: This is a 4 pin header but only 3 or 2 connections need to be used.  To connect to a DIN cable, either GND, 5 (to pin 5, current sink/aka -), and 4 (to pin 4, current source/aka +) should be used.  For internal module to module connections, only pin 4 and 5 should be used.  The ground pin is only for the shield in a midi cable, it is never connected on a midi input and isnt necessary for the short module to module lengths

 

I2C Header: 3 pin header to connect to other I2C devices in your rack, this is an unbuffered connection so cable lengths should be as short as possible (20cm/6" recommended).  There are 4.7k pull up resistors on this connection

 


 

Module Config DIP switch: This allows you to switch between I2C Follower and I2C Leader modes easily.  Simply move the switch to the "lead" position and restart the module (you can press the blue reset button once).  The other 3 positions are for future expansion and not currently implemented.

 

Connector for Expander: This connects the XVI to the I/O expander.  The cable is attached to the expander.  Note the keyway at the top of the part, the connecter will ONLY connect one way

 

FIRMWARE UPDATES:

 

 

Firmware update procedure:  Connect the Mini USB to your computer, power up the module and press the blue reset button on the back of the module twice (quickly).  A new drive will appear on your computer, simply copy the firmware file to that drive (it will give you a warning about copying a file without properties) and thats it.  The drive will disappear once the file is copied and the module will reboot with the new firmware.
