Frequently Asked Questions
Everything you need to know about GNM-23.
GNM-23 is a VST3 plugin that faithfully emulates a legendary 1981 analog BBD (Bucket Brigade Device) delay and reverb unit. Every circuit component is modeled from the original hardware schematics — 10 BBD TDA1097 chips, NE570 compander circuit, VCO clock generator, and analog tone filter.
RTNeural is an open-source neural network inference engine optimized for real-time audio. GNM-23 includes an RTNeural slot for loading trained analog character models.

The VST3 plugin takes up about 4MB. No additional software, servers, or AI models required.
GNM-23 is a lightweight DSP plugin. It uses less than 1% CPU. No GPU required. Works on Windows 10+, macOS 11+, and Linux.
