With the Black LPG, Erica Synths is expanding its high-quality Black Series to include a low-pass gate with its own decay envelope and CV control. The LPG functions as a VCA, a filter or a combination of both. Naturally, it also produces the famous ‘wooden’ Buchla bongos; as a bonus, the resonance can be overdriven. The extremely fast decay envelope effectively meets the need for sounds with a percussive character. In addition, an external control voltage can be fed in. If an LFO is used for modulation in VCA mode, this produces lovely tremolo effects with the characteristic timbre of Vactrol components.
