Patchbay-Equipped Synthesizers
What is a Physical Patchbay?
Traditional subtractive synthesizers have a fixed, pre-wired signal path (often called a normalled path): the oscillator feeds into the filter, which feeds into the amplifier, controlled by envelopes and LFOs.
Semi-modular synthesizers break this mold by providing a physical patch bay. By inserting physical patch cables (usually 3.5mm TS mini-jacks), you can reroute control voltages (CV) and audio signals to create brand new sound routing maps.
Plugging a cable into an input jack overrides the internal default connection. This lets you modulate the filter cutoff with an envelope output, split an oscillator signal to ring-modulate another voice, or sync complex LFO waveforms across external eurorack setups.
💡 Preset Hub Mappings: Since voice parameters on patch bay synthesizers are typically physical only and do not respond to MIDI CC automation, closeby.one lets you document and store your physical patch cable configurations and usage notes digitally, so you can share and recall your modular patches.
Instruments with Patchbays (10)
MicroBrute
The Arturia MicroBrute is a compact analog monophonic synthesizer featuring a Steiner-Parker multimode filter, multi-wave oscillator with unique shape modifiers (Ultrasaw, Metalizer, Pulse Width), a 64-step sequencer, and a Mod Matrix CV patch bay. NOTE: Voice parameters (such as filter cutoff, resonance, and oscillator levels) are controlled by physical potentiometers on the analog signal path and do not transmit or receive MIDI Continuous Controller (CC) messages. However, the MicroBrute receives Web MIDI note tracking, pitch bend, clock synchronization, and MCC sequencer pattern configuration.
MiniBrute 2
The Arturia MiniBrute 2 is a semi-modular monophonic analog synthesizer featuring a 25-note velocity-sensitive keyboard with aftertouch, an intuitive arpeggiator/sequencer, and a massive 48-point CV/Gate patch matrix. Its 100% analog discrete voice architecture combines dual VCOs with waveform mixing, a Steiner-Parker multimode filter, and Brute Factor feedback saturation. NOTE: Voice parameters (such as filter cutoff, resonance, and oscillator levels) are controlled by physical potentiometers on the analog signal path and do not transmit or receive MIDI Continuous Controller (CC) messages. However, the MiniBrute 2 fully supports Web MIDI note sequencing, clock synchronization, pitch bend, velocity, aftertouch, and MCC configuration.
MiniBrute 2S
The Arturia MiniBrute 2S is a semi-modular monophonic analog synthesizer that replaces traditional keys with a sophisticated 64-step triple-track sequencer, 16 velocity-and-pressure-sensitive pads, and an expansive 48-point CV/Gate patch matrix. Its pure 100% analog sound engine features dual VCOs with waveform waveshapers (UltraSaw, Metalizer, Pulse Width), a 12dB/oct Steiner-Parker multi-mode filter, and the signature Brute Factor overdrive. NOTE: Voice parameters (such as filter cutoff, resonance, and oscillator levels) are controlled by physical potentiometers on the analog signal path and do not transmit or receive MIDI Continuous Controller (CC) messages. However, the MiniBrute 2S fully supports Web MIDI note sequencing, clock synchronization, transport control, velocity, aftertouch, and MCC pattern configuration.
Crave
The Behringer Crave is an analog semi-modular synthesizer combining a classic Curtis-clone CEM3340 VCO, a 24dB/octave Moog-style ladder filter, a 32-step sequencer with 64 pattern memories, an arpeggiator, and a comprehensive 32-point Eurorack-compatible patchbay. Parameters like oscillator pulse width, filter cutoff, resonance, and envelope shapes are controlled hands-on via physical knobs, while MIDI CC controls select parameters like Glide time and envelope times.
Edge
The Behringer Edge is an analog semi-modular percussion synthesizer inspired by the Moog DFAM (Drummer From Another Mother). It features dual analog VCOs with Triangle and Square waveforms, oscillator hard sync, frequency modulation (FM), a switchable 24dB 4-pole low-pass / high-pass ladder filter, a white/pink noise generator, and dual 8-step analog pitch and velocity sequencers integrated with a 15-point Eurorack-compatible patchbay. Parameters are physical-only, responding to Web MIDI clock sync and note/step triggers.
K-2
The Behringer K-2 is an analog semi-modular synthesizer clone of the classic MS-20, featuring dual VCOs, ring modulator, and highpass/lowpass peaky filters.
Model 15
The Behringer Model 15 is an analog semi-modular synthesizer clone of the classic Moog Model 15 modular system, featuring dual oscillators, a legendary 24dB ladder filter, and a flexible patch bay.
Model D
The Behringer Model D is an authentic discrete analog desktop synthesizer inspired by the legendary Minimoog Model D. It features three voltage-controlled oscillators (VCOs) with 5 variable waveshapes, a classic 24dB/octave ladder filter with self-oscillation, an analog pink/white noise generator, an external audio input with overdrive loop capability, and Eurorack-compatible CV/Gate patch points. NOTE: Voice and filter parameters are wired directly to physical potentiometers and do not transmit or receive MIDI Continuous Controller (CC) messages. However, the Model D responds to Web MIDI note tracking, pitch bend, gate triggering, and MIDI clock sync.
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.
PRO-1
The Behringer PRO-1 is an analog semi-modular paraphonic synthesizer recreation of the legendary Sequential Circuits Pro-One, featuring dual Curtis-clone CEM3340 oscillators, a 24dB/oct 4-pole lowpass filter, dual 4-stage envelopes, dual 64-step sequencers, and Eurorack-compatible CV/Gate patch points. NOTE: Voice parameters (such as cutoff, resonance, mixer levels, and envelope times) are controlled by physical potentiometers on the front panel and do not transmit or receive MIDI Continuous Controller (CC) messages. However, the PRO-1 receives Web MIDI note tracking, pitch bend, gate triggers, and paraphonic dual-note allocation.
