Analog Synthesizer Behringer 2600 37-key Semi-modular — monophonic, patchable voice

Behringer 2600 is a 37-key semi-modular analog synthesizer that delivers a single monophonic voice with extensive patchability. Its architecture reproduces classic modular signal flow with dedicated oscillators, multimode filtering, envelope generators and patch points accessible on the front panel. The instrument is designed to provide hands-on control for studio sound design, live performance and experimental patching without the need for internal soldering or module swapping.

Advantages

The semi-modular design offers immediate playability straight out of the box while allowing deep routing via patch cables for customized signal paths. Dedicated front-panel controls for oscillators, filter and envelopes enable precise timbral shaping. The physical keyboard with 37 keys supports expressive manual control, and the monophonic voice focuses processing resources on a single, robust signal path for clear basslines and lead sounds. Connectivity options simplify integration into existing studio setups.

Suitable for

• Studio sound design and synthesis experimentation
• Live electronic performance and modular-style patching on stage
• Creating monophonic basses, leads and effects
• Educational use for learning modular synthesis signal flow

Key specifications

• 37-key semi-weighted keyboard with manual play control
• Monophonic analog voice with patchable signal paths
• Multiple oscillators with waveform selection and tuning controls
• Voltage-controlled filter with cutoff and resonance controls (multimode or classic ladder-style topology depending on model specifics)
• Envelope generators for amplitude and filter modulation
• Extensive front-panel patch points for flexible routing and modulation
• Dedicated modulation sources including LFO and external input options
• Standard audio outputs and synchronization/clock connectivity for integration

How to use

Connect the synthesizer to a mixer or audio interface using the main outputs and power it on. Play the 37-key keyboard to trigger the monophonic voice, then adjust oscillator tuning and waveform controls to set the basic tone. Shape timbre with the filter cutoff and resonance and apply envelopes to control amplitude and filter dynamics. For custom patches, insert patch cables into the front-panel jacks to reroute audio and control voltages, enabling complex modulation networks and signal interactions. Use the LFO and external inputs as modulation sources or sync the unit with other gear via clock connections.

Recommendations

For stable performance in studio and stage contexts, allow the unit to warm up briefly after power-on, use high-quality patch cables to avoid noise in patch points, and set buffer levels appropriately on your audio interface to prevent latency when recording. When exploring modular patches, document interesting cable routings and knob positions to reproduce sounds reliably.
