Line 2:
The concept of the lowpass gate originated with the [[Buchla, Donald|Buchla]] 200 series [[modular synthesizer]] series, which offered a lowpass gate as a module in the series. The Buchla design used a [[vactrol]] to process the [[control voltage]] input; the vactrol had certain non-linearities which made the lowpass gate a good module for imitating some tuned percussion sounds. By feeding in short bursts of noise, or just impulse spikes, the lowpass gate could be made to produce sounds that resembled hand drums, congas, steel drums, or marimba. The original Buchla module is highly sought after and has inspired a number of imitators over the years.
