OSC SYNC mod for Behringer Neutron

A description of how I modified my Behringer Neutron synthesizer,
adding circuitry known from the Prophet 5 rev3, allowing for a much cleaner OSC SYNC
sound than the Neutron’s native one. An added flip-switch on the front panel now allows me to
toggle between the Neutron’s harsh default sync and the smooth, modded behavior that is
also heard in the Behringer Pro-1.

Inspiration / Must-Reads

Sound demo/comparison of native vs. modded OSC SYNC

See this YouTube video.

Requirements

The whole circuit is extremely inexpensive. I had old, used SMD components lying around,
so it cost me nothing except for the €1 flip switch from Amazon.

  • BC859 PNP transistor
    (because I had one at hand; the other guy used a BC858, and the Prophet scheme suggests a 2N4250)
  • resistor 10k
  • resistor 47k
  • cap 100nF
  • cap 200pF
  • 1 flip switch (3-pole, ON-ON)
  • you will also want enough shrinkwrap at hand
