Dynamics Controller Bat

Modern, Variable Decay Low Pass Gate

Both a resonant filter and a VCA, the Pittsburgh Modular Dynamics Controller Bat is a modern reinterpretation of Don Buchla’s famous “lowpass” gate.

Unlike a VCA, which simply changes the loudness of the sound without modifying the harmonic content, the lowpass gate circuit uniquely simulates the characteristics of how sounds interact in natural environments.

When used in lowpass gate mode, louder sounds contain more harmonic content and quieter sounds contain less harmonic content. The result is a more organic, complex, and rounded sound.

Don Buchla’s original lowpass gate (LPG) was limited to a static response time that varied from unit to unit. For better or worse, this made each lowpass gate a little different. Pittsburgh’s research that has made its way into the Dynamics Controller Bat solves this issue. It modernizes Don Buchla's concept by adding a unique voltage controllable response curve and variable resonance to the lowpass gate. This allows for all the sonic depth of the LPG while providing the same kind of sustain control offered by a more traditional VCA. The resulting Pittsburgh innovation is the best of both worlds, natural and alive sound, that's completely controllable.
