About the Synth Geekery Show

Synth Geekery is a weekly podcast/live stream (YouTube) show about everything synthesizers, drum machines, samplers, sequencers, eurorack and music technology. We take the “one of the masses” viewpoint, where we are also users of gear just like you (read: we’re not influenced by commercial product placement).

The show relies on the generous contributions of the synth community. You can contribute in many ways including supporting us via our YouTube Channel Membership or Patreon. We also have regular and special video guests: if you would like to take part in future shows – please contact me via email on the about page here.


This week’s video guests are:

Andrew Brooks

News from the Geekery

This week we have a big list of new synths and gear:

DivKid Stereo Mix

The latest 6HP module from DivKid – the Stereo Mix: brings a mixer channel strip into your modular. The module offers the following features:

  • Stereo (or normalised mono) inputs – 3.5mm
  • 3 Band EQ with low shelf, mid bell and high shelf response
  • Input level selector for either eurorack or line level input gain
  • 3-way mute toggle switch for on, off or momentary mute function
  • Stereo VCA level control that is CV controllable with level attenuation
  • Manual pan control and CV control of pan and attenuator
  • Output level selector for eurorack or line level

Some stand-out features include the dot indicators on the level knob that helps with 5V, 8V and 10V CV voltage levels (which helps with differences in EG CV outputs). There is also soft clipping on the levels with controls to line level or eurorack level outputs. Because the output is stereo, the module can also be used as a two mono line mixer output.


Price: $220

Oberheim OB-XA

Leaked information sourced from shows the new Oberheim synth as the OB-X8. Here’s the details:


  • 8-voice, pure-analog polyphony with sine, saw, square, triangle, and noise
  • Two discrete SEM/OB-X-lineage VCOs per voice deliver classic punchy Oberheim tone
  • Discrete SEM-lineage VCFs deliver authentic OB-X-style tone and presence
  • Genuine Curtis filters add bold OB-Xa/OB-8 character
  • Meticulously modeled envelope responses match each OB model: OB-X, OB-Xa, and OB-8
  • The 61-key FATAR velocity- and touch-sensitive keyboard allows unparalleled expression and responsiveness
  • Bi-timbral capability allows two presets simultaneously for splits and doubles
  • 400-plus factory programs, including the full set of factory sounds for the OB-X, OB-SX, OB-Xa, and OB-8
  • Integral, fanless, heatsink-free power supply
  • Real walnut end cheeks
  • High-resolution OLED display enables patch management and easy access to advanced features
  • Classic Oberheim Pitch and Mod levers allow expressive note bending, vibrato, and access to arpeggiator functions


  • Additional SEM Filter modes add high-pass, band-pass, and notch functions to the classic OB-X filter
  • Vintage knob allows variable amounts of voice-to-voice variability to emulate the behavior of vintage instruments
  • Velocity sensitivity adds expressiveness to volume and filter
  • Channel Aftertouch adds real-time performance-based modulation
  • Enhanced unison allows variable voice stacking from 1-8 voices
  • Variable triangle wave cross-modulation
  • Over 600 user-programmable preset locations
  • Programmable per-voice pan allows wider stereo presence
  • Variable oscillator and noise levels

Ins & Outs:

  • Stereo and Mono outputs
  • Volume, Sustain, and Filter inputs
  • Arpeggiator clock input
  • MIDI In, Out, Thru
  • USB


Price: $5000

AJH Synths – Multi-Burst Envelopes (MBE)

AJH Synths new 12HP module “Multi Burst Envelopes” can create anywhere from one to forty envelopes in succession. The top knob allows you to choose from eight different envelope shapes. This becomes more fascinating when you put in a CV modulation source and start flipping envelopes in the middle of a burst. The bursts can be triggered from the front panel or via a Gate or Trigger input. This can be done as a one-shot or retriggered to restart the input sequence.

The burst repeat rate is regulated by an internal LFO rate, although it can also be changed externally. The pulse width control or, once again, CV is used to alter the envelope length. Slope adjusts the envelopes’ level, allowing you to fade them in and out over time. Two LEDs at the top display the burst rate as well as the envelope level, which is quite useful.

This type of module has a wide range of uses. From pulsing gates to ratchets and fascinating bursts of filter activity to strumming resonators, the possibilities are endless. You can get some amazing modulations by combining the bursts with creative CV control.


Price: 230 GBP
