• New code update! Version 1.0.2 allows jumpers to select Gate or Trigger outputs, and to select Up-beat or Down-beat counting. See the manual for more information:
• How to Update your own RCD by yourself: Download the hex file below. Then follow these instructions: Updating Firmware on AVR chips
• Version 1.0.2: hex file
• AVR Studio4 Project directory (in case you want to compile it yourself): rcd_project.zip

If you don't want to buy the AVR ISP mkII and update your RCD yourself, you can either contact the dealer you purchased your RCD from about an update, or purchase one from 4ms directly (scroll down to RCD Chip): 4ms Kits page

• User Manual Version 1.0.2 (updated June 11, 2010)
• version 1.0 user manual (old version)
• How CV Rotation works Graphical!

• 4 H.P. Eurorack format
• Divide-by-1 to Divide-by-64, on 8 output jacks
• CV Rotate jack to shift divide-by amount on each jack
• CV Reset jack to reset/re-sync all jacks
• Optional break-out panels to expand functionality (MIDI, Auto-reset, selectable Divide-by range, Gate/Trigger, Up/Down-counting)

• Clock Input (5V to 15V clock, rising edge triggered), max 3kHz
• CV Rotate (0V to +5V input)
• CV Reset (5V to 15V trigger)
• Divided Clock Outputs (8 jacks):
  • Divide-by-(1+R)
  • Divide-by-(2+R)
  • Divide-by-(3+R)
  • Divide-by-(4+R)
  • Divide-by-(5+R)
  • Divide-by-(6+R)
  • Divide-by-(7+R)
  • Divide-by-(8+R)
  ...where R is the CV Rotation.
• Selectable Gate/Trigger mode:
  
• Selectable Divide range up to Divide-by-64:
  Two jumper pins on the back can be pre-set with jumpers plugs, or used with (forthcoming) breakout panel.
• Selectable Auto-reset:
  Auto-reset will reset the divide counter every 16/24/32 clocks, which keeps the beats more "dance-able" even when using the "weird" clock divisions (3/5/6/7/9/10/11/etc..) Two jumper pins on the back can be pre-set with jumpers plugs, or used with (forthcoming) breakout panel.
