Neutron
The Behringer Neutron is an analog semi-modular paraphonic synthesizer featuring dual Curtis-clone CEM3340 VCOs, a two-pole multi-mode Moffat filter, an analog BBD delay, a distortion overdrive circuit, and a massive 56-point Eurorack-compatible CV/Gate patch matrix. Its pure discrete analog signal path produces aggressive leads, paraphonic duophonic chords, and experimental noise textures. NOTE: Voice parameters (such as filter cutoff, resonance, overdrive, and delay time) are controlled by physical potentiometers on the front panel and do not transmit or receive MIDI Continuous Controller (CC) messages. However, the Neutron receives Web MIDI note tracking, pitch bend, gate triggering, and paraphonic voice allocation.
💡 How to configure the Behringer Neutron in closeby.one▼
To connect your Behringer Neutron to your web browser, connect your synth using a USB cable or a dedicated USB-to-MIDI interface.
Open the MIDI Settings panel above, set the Output Port to your connected Neutron device, and select the correct MIDI channel (default is channel 1). Once configured, you can trigger notes, play sequences and arpeggios, synchronize master MIDI clock, and document patch routing sheets directly in your browser.

Physical Patchbay Connections
0 CablesPhysical Discrete Analog Architecture
The Behringer Neutron utilizes a discrete, hands-on analog signal path where timbre parameters (such as filter cutoff, resonance, oscillator waveform mixers, and envelope timings) are wired directly to physical potentiometers. Because there are no digital encoders or DAC-controlled VCAs on the parameter circuits, voice controls do not transmit or receive MIDI Continuous Controller (CC) values.
However, the Neutron integrates seamlessly with closeby.one for Web MIDI note sequencing, polyphonic/monophonic melody lines, arpeggios, and rock-solid MIDI clock synchronization.

MIDI Troubleshooting
🚨 Enabling Paraphonic (Duophonic) Playing
Press the PARAPHONIC button on the front panel (it will illuminate). When sequencing two notes from closeby.one or a MIDI keyboard, VCO 1 will track the lower note and VCO 2 will track the upper note simultaneously.
🚨 Setting the MIDI Channel on the Neutron
The Behringer Neutron uses 4 DIP switches on the rear panel to set its MIDI receive channel (1–16). Set all 4 switches down (OFF) for MIDI Channel 1, or use the Behringer Neutron App over USB to customize channel settings.
🚨 Calibrating VCO 1 and VCO 2 Tuning
Allow the analog circuits to warm up for 15 minutes. To initiate automatic auto-tune calibration, hold down the OSC SYNC and PARAPHONIC buttons simultaneously for 5 seconds until the LEDs cycle.
