Use only high-quality professional speaker cables with ¼" TS or twist-locking plugs pre-installed. All other installation or modification should be performed only by qualified personnel.
NEUTRON User Manual About the Neutron • Paraphonic, dual analog VCO design which allows for ingenious music creation. • Semi-modular design requires no patching for immediate performance. • Dual 3340 VCOs authentically recreate the classic sound creation. • 32 in/24 out jack patch bay for sound patching experimentation. • 5 variable oscillator shapes with pulse width modulation for high quality sounds. • Blend or switch the OSC & LFO shape. A unique sound creation tool.
NEUTRON User Manual 1. Introduction An ultra-affordable leap into the warm world of analog synthesis, the Behringer Neutron gives you the power to create virtually any monophonic sound imaginable with incredible power and ease. The pure analog signal path is based on the legendary V3340 VCO chip with variable oscillator and LFO shapes which can be blended or switched for unique sound creation.

NEUTRON User Manual 4. Overview This overview will help you set up the Neutron analog synthesizer and briefly introduce its capabilities. 4.1 Connection You can adjust the SHAPE control for each oscillator to select different waveforms, if in blend mode, the waveforms will morph into one another in a smooth transition. The five oscillator shapes are: The Neutron has a ¼" (6.35 mm) mono jack output on the rear of the unit which is also duplicated on the patch bay via a 3.5 mm output.
NEUTRON User Manual 4.5 Filter Section 4.6 LFO Section The Neutron has a powerful 12 dB filter with three modes available: The Neutron LFO has a frequency range of 0.01 Hz to 10 kHz. This allows low frequency modulation up to audio rate modulation using the LFO. (13) (12) The Shape control sets the type of LFO waveform. When selecting the LFO waveform, the control can be set to select between fixed types or to blend between wave shapes.
NEUTRON User Manual 4.7 Delay Section 4.10 Sample And Hold The Neutron has an impressive analog bucket brigade delay section. Delay times of 24 ms to 640 ms can be set. Effects from long dub delays to extreme chorusing can be created. Set the MIX control at 12 o’clock. Then try turning the RATE control fully left with the REPEAT control to the right a little for a long dub style sound.
NEUTRON User Manual 5. User Configurable Options & Features 5.6 Tune Pot Bypass All features in this manual require software version V2.0.X or higher in order to function correctly. Please visit the www.behringer.com to find the latest software version. Press and hold OSC (1 or 2) RANGE and PARAPHONIC buttons until the selected OSC octave LED starts to flash. This indicates that the tune pot for that OSC is now inactive and all notes played are in tune.
NEUTRON User Manual 5.13 VCF Mod Source 5.17 Pedal Mode Long Press VCF Mode then the LFO shape LED wheel will indicate the current mod source selection: Press & hold OSC2, then pressing KEYTRK will toggle the state of of the mode. Not used When the KEYTRK LED is lit - OSC 2 will play the last note played before Pedal Disabled Mode was enabled with each new note played. This starts when any key is pressed. Note-On velocity When KEYTRK LED is not lit - OSC2 will behave normally.

NEUTRON User Manual 6. Eurorack Installation The Neutron synthesizer can be taken out of its factory chassis and fitted into a standard Eurorack case (not supplied). We recommend that this procedure is undertaken only by an experienced service technician, to prevent personal injury, or damage to the unit. The Eurorack case will need its own suitable power supply unit to power the Neutron synthesizer.
NEUTRON User Manual 7. Software Update & Calibration 5. In the VIEW menu, select SysEx... 7.1 Software Update The Neutron DFU (Device Firmware Upgrade) updater can be downloaded by going to www.musictribe.com Please follow the steps documented in the release notes accompanying the update. 7.2 Assign Out Calibration This calibration has been carried out by the factory at the manufacturing stage but instructions are described here if needed. For this, you'll need a 3.
NEUTRON User Manual 7.3 Bucket Brigade Delay Calibration Clock Noise Calibration The Neutron Delay stage is designed to give as much control and variety as possible to the user. With that in mind, it may be necessary to tweak your Neutron to sound the way you want it to. Once the repeats calibration has been completed you may need to dial out some clock noise from the delay output.
NEUTRON User Manual 8. Patch Bay 8.1 Tips and Tricks of the Patch Bay In a patchable semi-modular synthesizer such as the Neutron, inputs and outputs are independent from one another. It is up to the user to patch the modules together as they wish. This is different from a normalized synthesizer where the functions are hard-wired together and the user just changes parameters. Patchable modular synthesizers are more complex to operate but give infinite options.

NEUTRON User Manual 10. Preset Patches 11. Troubleshooting The following examples give you a glimpse into the wonderful world of modular synthesis. Try these patches to show the versatile power of the Neutron. Before turning on the Neutron power, please check that: Default Patch - This is a great starting point for sound creation. No patching required. A standard sawtooth sound will be audible using these settings. Your speakers or headphones are correctly connected.
NEUTRON User Manual 11.5 Buzzing or humming sounds can be heard from the audio outputs. USB and or audio connections made between different devices using different power supplies, sources or sockets can sometimes create ground loops. You can attempt to resolve these grounding issues between computers and the Neutron by following good grounding practice and ensuring all devices use the same ground point.

NEUTRON User Manual 13. Appendix A This table lists the SysEx commands supported by the Neutron. MIDI Control Change (CC) functions Note that the general format of a Neutron SysEx message is: There are 2 MIDI CC functions that the Neutron supports: • Modulation wheel or lever - MIDI CC 0x01 (MSB) & MIDI CC 0x21 (LSB). This is routed to the assign out when selected as the assign out option • Damper Pedal on/off (Sustain) - MIDI CC 0x40.

To use the app, simply download the latest version from the www.musictribe.com website and follow the installation instructions. Any Neutron will need to be updated to version V2.0.
NEUTRON User Manual 16. Glossary NEUTRON GLOSSARY This glossary provides an explanation of useful symbols, terms and abbreviations. 32'/16'/8': Used to describe the range of an oscillator, this term originates from pipe organs. for example, an 8' pipe is one octave higher than an 16' pipe. ADSR: Attack, Decay, Sustain and Release, an envelope with four stages.
NEUTRON User Manual Overdrive: To push to excess or drive too hard. Slew Rate: The rate of change of a voltage or control signal. Parameter: A setting whose value can be changed. Soft Clipping: is a technique for adding warm harmonic distortion to your audio. Parametric EQ: A type of EQ that allows all of the parameters of equalization to be changed, including center frequency, boost/cut in gain and bandwidth.
