Erica Synths Black LPG
Organic Buchla-style low pass gate with built-in envelope
10 HP Eurorack module
The Black LPG is a low pass gate module by Erica Synths combining a low pass filter and VCA in one unit, producing organic, natural-sounding responses reminiscent of Buchla-style vactrol circuits. It features switchable filter, VCA, and combined modes with built-in envelope generation triggered by gate signals, giving percussive plucks, smooth swells, and expressive timbral shaping in a compact package.
