Bastl Instruments Dark Matter: Voltage-Controlled Feedback Power for Eurorack

The Bastl Instruments Dark Matter is a sound processor and generator module tailored for modular synths, introducing voltage-controlled feedback and dynamic effects into Eurorack setups. Drawing on no-input mixer feedback techniques, the module enables complex, evolving soundscapes and tonalities. Feedback becomes a playable effect, providing extensive voltage control and hands-on modulation across multiple parameters.

Modular Feedback, Reimagined

What sets the Dark Matter apart is its thorough voltage control over not only feedback but also input drive, EQ, and crossfading. Performers can take advantage of an external feedback loop section, a dynamics envelope follower, and a four-mode overdrive circuit—textures range from subtle saturation to intense distortion. As a result, interactive performance possibilities emerge that are seldom found in other Eurorack processors.

Hands-On Controls and Patch Flexibility

With both physical and voltage control for every major parameter, creators can shape sound precisely. Working with the input VCA with soft clipping, voltage-controlled EQ, or crossfader, each function can be accessed from panel controls or via CV for advanced patching.

• Width: 13 HP — fits standard Eurorack cases, integrating easily into existing racks
• Skiff-friendly setups with limited space benefit from the Depth: 24 mm
• Power Consumption: <75 mA (+12V), <75 mA (-12V) — efficient for dense modular systems

Voltage Control for Deep Sonic Manipulation

True voltage control is a cornerstone of the YRS-23, inviting users to modulate parameters like feedback amount, EQ bands, and crossfade in real time for evolving, reactive sounds. Percussive processing and animated melodies both become possible thanks to this flexibility.

• Push signals into dynamic saturation with the Drive: Input VCA with gain and soft clipping, plus Hyper Drive switch
• Shape timbre and harmonic content live using the EQ: 2-band, voltage-controlled bass and treble boost/overdrive
• Establish rich, playable feedback paths via Feedback: Voltage-controlled, with phase and external loop options

Envelope Follower and Performance Dynamics

Tracking the amplitude of incoming signals, the envelope follower generates dynamic CV signals to modulate crossfade, feedback, and gating. As a result, it becomes ideal for ducking effects, rhythmically animated textures, and reactive signal sculpting.

• Envelope Output: 0–5 V — feeds crossfade or feedback CV for real-time dynamics
• Decay Switch: Low/High — tailor envelope speed to suit percussive or sustained material
• Nuanced modulation can be achieved by selecting the envelope source point with Pre/Post Drive Routing

Who Is It For: Creative Modular Synth Artists

This instrument is crafted for Eurorack users, sound designers, and experimental musicians eager to push feedback techniques beyond the conventional. Artists in need of a voltage-controllable, hands-on tool for evolving distortion, gating, and feedback-driven effects will find the YRS-23 indispensable for exploratory sonic work.
