RAVEN Is A 100% Analog Semi Modular Synth, On Kickstarter Now

Check out this bespoke analog synth voice that the developers are funding now, with earlybird specials available.  

RAVEN is a 100% analog synth being developed by Birdkids, an independent Austrian outfit.  According to the developers, the system-architectural idea was about going back to the basics of subtractive synthesis. They wanted to capture the raw, non-linearity and honesty of a 100% analog circuit. The main engineering challenge of RAVEN was consolidating a highly complex conglomerate of modular, discrete designs into a slim 3U/42HP (Eurorack) form-factor resulting in a uniquely sounding subtractive, semi-modular, high-performance, musical instrument.

RAVEN is comprised of:

  • Dual, wide-range Voltage Controlled Oscillators.
  • The original TheBateleur (â"‡ pending) Voltage Controlled Filter.
  • Two Voltage Controlled Amplifier outputs -
  • A high-performance THAT2162 Blackmerâ"‡ VCA and an
  • Optocoupler VCA reminiscent of legendary West-Coast designs.

"To us, analog is about texture, it’s about depth of emotion - it’s the beauty in imperfection. Those are human values, they're timeless, they enrich our everyday experiences. That is why we've developed RAVEN, a 100% analog, semi-modular, synthesizer voice. 

RAVEN is the synthesizer we’ve always dreamed of making from day one. Building on a legacy of years of technological research, design and manufacturing as well as the tremendous success of our previous modular line, TheBateleur, we had quite a few challenges to face during the creation process."


RAVEN combines the simplicity of a performance-friendly, semi-modular synthesizer voice with fully-modular, infinitely flexible, workflow possibilities by assigning Control Voltage I/O’s at (almost) every point in the signal workflow. Each modular component can be seen as a standalone, self-sufficient entity.
The VCF can be bypassed to allow for a VCO (I+II Sum) to VCA operation and thus used as a standalone VCF or third voice in self-oscillation, perfectly tracking 1V/Oct by choice.


  •     1V/Oct (Pitch tracking) relative and absolute options for both oscillators and VCF.  
  •     FM (Linear Frequency Modulation) per VCO.  
  •     PWM (Pulse Width Modulation) per VCO.  
  •     SYNC per VCO.  
  •     Crossfader between VCO’s.  
  •     External Audio Signal Input.  
  •     VCF Cutoff.  
  •     VCF CV Input.  
  •     VCF Resonance.  
  •     VCA CV Input.  


  • Individual Waveform outs for each VCO (Saw, Triangle, Pulse / Square).
  • Noise Output.  
  • Filter Output.  
  • Clean Out (Linear THAT2162 Blackmerâ"‡ VCA).  
  • Opto Out (Optocoupler VCA, West-Coast style response).  


  • Waveform selection toggle per VCO.  
  • PW position for VCO II.  
  • PWM amount either individually for VCO I or normalized for both.  
  • FM amount either individually for VCO I or normalized for both.  
  • Coarse Tune for VCO I (relative or absolute via jumper).  
  • Fine Tune for VCO II (relative).  
  • Crossfader position VCOs I/II.  
  • External Audio Signal Input Amount.  
  • VCA CV Amount / Initial VCA Gain.  
  • VCF Cutoff position.  
  • VCF Mode switch*
  • VCF CV Amount.  
  • VCF Resonance position / CV Amount.

MSRP: 949 Eur. Numerous early bird deals and bundles available.
