ReArranger CV Randomizer

Note / Gate utility


  • • Create your own multi sampled instruments
  • • Controlled randomization with value displays
  • • Responds to MIDI and CV input

Audio examples

The ReArranger CV Randomizer is a Rack Extension Utility for Reason. It tests whether Note and/or Gate input (CV and/or MIDI) is in range and above threshold. If so, it applies changes to the input values and outputs those values at Out 1. If not, the input is sent unaltered to Out 2. The operation of the device can be interpreted as an if-then-else statement made in programmers code.

Great for manipulating CV and MIDI in a controlled manner, even randomization!
