With a distinctly Celtic twist of inventiveness, the Pas-Isel Eurorack module by Dwyfor Tech is a fascinating exploration into the vistas of filter-based sound modulation. The audacious innovation at its heart, a 'wooly' four-pole resonant lowpass filter, brings an exciting new voice to the modular synthesizer landscape.
Deriving its unique character from an amalgamation of design elements from industry stalwarts, Buchla and Korg, Pas-Isel's diode-based VCF (Voltage Controlled Filter) is engineered to utilize highpass filters in op-amp negative feedback loops. This brilliant bit of engineering results in generating a signature -24dB lowpass response that fits the lively persona of the module itself and has swiftly become its defining characteristic.
The name 'Pas-Isel', translating to 'low-pass' in the Welsh language, is a fitting foreshadowing for the device's sonic capabilities. In keeping with the Celtic theme, the enchanting 'wooly jumper' sound is unique to this module and provides the user with a soundscape rich in texture. It's as if you've clothed your music in a cozy, warm sweater - enhancing its allure and intrigue.
At lower input levels, the Pas-Isel module displays a clean, sophisticated and Moog-esque demeanor that can perfectly integrate into a variety of musical scenarios. Increase the gain, and you can witness the module transform, revealing a compelling saturation that imbues your compositions with a flavor and warmth that's uniquely its own. This tonal versatility allows the Pas-Isel to feel equally at home with chorussy, luscious synth pads or on pungent, aggressive acid basslines with single VCOs (Voltage-Controlled Oscillators).
An essential underpinning of this module’s design philosophy is the focus on playability and user interaction, which is amply reflected in the smartly-spaced and generously-sized knobs. It is a module designed as much for the fingers as it is for the ears, making it an excellent choice for live performances where tweakability and control are paramount.
In conclusion, the Pas-Isel module by Dwyfor Tech is an adventurous and singular addition to the pantheon of Eurorack modules. It is a testament to the endless possibilities available in the modular world. As a four-pole resonant lowpass filter with a rich, warm signature sound, the Pas-Isel is a ‘must try’ to every audiophile looking for an inspiring new piece of gear.
Available for purchase at the Dwyfor Tech store on Reverb, it provides all sound adventurers with comprehensive documentation to help exploit its full potentials. This is an invitation to experience the Celtic charm of Eurorack and infuse your modular journeys with some 'wooly' warmth.
