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.

News
AMSynths AM1064 TRIG CNTL
AMSynths proudly announces the immediate release of the AM1064 – a versatile dual trigger converter designed to bring expressive control and precision to your modular setup.
The AM1064 responds to gate signals or front panel touch (with latching control), generating two high-accuracy voltages. Each output offers a selectable 10V or 2V range, adjustable smoothly down to 0V, making it perfect for shaping dynamic textures in filters, VCAs, and oscillators. Another nice feature is the on/off momenary push button which latches the CV and gives the module a performance playable control. Additionally, there is a separate gate input which provides a V-trigger with a red indicator LED that shows when the voltages are on.
Whether you’re using a sequencer, keyboard, or manual control, the AM1064 adds depth and nuance to your sound.

Synthetic Sound Labs 1015 Low Pass Gate
The SSL 1015 Lowpass Gate is a modern take on the classic “Vactrol” VCA/VCF concept, inspired by Don Buchla’s iconic 292C module. Depending on the selected mode, it functions as a VCA, a 2-pole lowpass filter, or a combination of both—renowned for delivering warm, natural-sounding plucks and percussive textures. In filter mode, the 1015 introduces a distinctive resonance feedback circuit that opens up a wide range of sonic possibilities, from tightly controlled percussion to untamed oscillations.
Unlike earlier designs that relied on cadmium-sulfide (CdS) photocells—now restricted in the EU and other regions—the SSL 1015 pioneers an environmentally conscious approach. It utilizes an innovative Vactrol alternative that eliminates CdS materials, offering a future-friendly solution embraced by users worldwide.
For users in the USA who prefer the classic CdS character, a special edition with original CdS components is available by direct request for an additional cost.
🔧 Specifications:
| Feature | Function |
|---|---|
| Controls | – OFFSET: Initial VCA / VCF level – RESONANCE: Filter feedback amount (Filter mode only) – CV AMT: FM Input with Inverting Level Control |

Behringer Skies
The Behringer SKIES is a digital Eurorack module that brings granular audio processing to modular synth setups. It is a faithful recreation of the iconic Mutable Instruments Clouds, an open-source granular synthesis module that became a classic for ambient soundscapes, textured audio layering, and experimental sound design. SKIES inherits the powerful feature set of Clouds while delivering it in Behringer’s accessible and budget-friendly format.
This module allows users to manipulate audio in real time by splitting it into “grains,” which can be altered in pitch, size, density, and timing. Ideal for transforming simple sounds into lush, evolving textures, SKIES is suited for both live performance and sound design applications.
Key Features:
- Based on the open-source Mutable Instruments Clouds module
- Granular synthesis engine with real-time audio manipulation
- Control over grain size, density, position, texture, pitch, and blend
- Built-in reverb and pitch-shifting effects
- Stereo inputs and outputs for rich, spatial processing
- Freeze function for sampling and looping short audio segments
- CV modulation inputs for all key parameters
- Four distinct processing modes, including granular, pitch-shift, time-stretch, and spectral effects
- Skiff-friendly Eurorack format
- Rugged build with Behringer’s standard aluminum faceplate
Specifications
| Feature | Data |
|---|---|
| Size | 18HP |
| Power consumption | +12 V 120 mA, -12 V 10 mA |
| Resolution | 8-bit/16 kHz to 16-bit/32 kHz (buffer 1 to 8 secs) |
| USB | Type C socket |
| CV inputs: Position, Size, V/Oct, Blend, Density and Texture | 3.5mm TS jack, -8 V to +8 V range, with impedance at 50 kΩ |
| CV inputs: Freeze, Trigger | 3.5mm TS jack, 5 V peak to peak, with impedance at 50 kΩ |
| Audio inputs (left and right) | 3.5mm TS jack, AC coupled, impedance 22 kΩ |
| Audio outputs (left and right) | 3.5mm TS jack, AC coupled, impedance 1 kΩ |
| Dimensions | 128.5 x 91.12 x 55.7 mm (5.06 x 3.59 x 2.19″) |
| Weight | 187 g (6.6 oz) |
The Behringer SKIES is an excellent entry point into granular synthesis for Eurorack users, especially those who missed out on the now-discontinued Mutable Instruments Clouds.
Price: expected to be $99 USD
