Archaea Exchange Expander
24 Jun 2025 Archaea
Exchange Expander is now available as a 1U module. This module expands the inputs/outputs of Exchange and can send 8 signals across the back of a rack. https://archaea.co.uk/expander-1u 
Teia RipWave
22 Jun 2025 Teia
Introducing RipWave, a compact 6HP Analog VCO designed for rich sonic exploration in a small footprint. At the heart of its design is the Transform knob: a unique, voltage-controllable parameter that shapes the character of each waveform. It offers a wide range of timbral variation, from saturation to wavefolding, harmonic morphing, and pulse width modulation, all in a single control. 
AMSynths AM904C Filter Coupler
21 Jun 2025 AMSynths
AMSynths announces the fabulous AM904C filter coupler for adding amazing bandpass and band reject sounds to your Moog modular. The module connects to the Behringer 904A and B filter modules internally, and requires a small amount of SDIY. Three wires connect to the signal input, output and CV cutoff, with a 6-way IDC cable interconnects the modules from the rear. 
Wildfire Laboratories Kinetic Work
20 Jun 2025 Wildfire Laboratories
The WFL-459 “KINETIC WORK” is a two-input vactrol low-pass gate and distortion module. It’s our take on the classic active LPG module, featuring two inputs, switchable filter frequency responses, and “THE WILDFIRE SPECIAL” - dual infrared LED distortion. Kinetic Work is 6HP and skiff-friendly. 
Radical Frequencies Looping ADSR
19 Jun 2025 Radical Frequencies
New envelope module in 6hp! Radical Frequencies analog ADSR with loop function (instant LFO mode) and with internal jumper to select between slow or fast mode! And believe me this envelope can go very fast and snappy :)
