The Authentic Sound of
Analog Delay
GNM-23 faithfully emulates the Dynacord VRS-23, the legendary 1981 BBD delay/reverb unit. Real bucket brigade character with TDA1097 chip modeling, NE570 compander, and analog clock artifacts.
Circuit-Level Analog Emulation
Every component modeled from the original Dynacord VRS-23 schematics. Not a generic delay — a faithful recreation of a specific machine.
5× TDA1097 BBD Chain
Real bucket brigade device modeling with progressive bandwidth reduction, chip-specific noise floor, and analog clock artifacts per stage.
NE570 Compander
Authentic 2:1 compression before BBD and 1:2 expansion after — models the signal-dependent breathing and pumping of the original NE570 chip.
Echo & Reverb Modes
Dual operating modes from the original hardware. Echo with rhythmic repeats, Reverb with asymmetric multi-tap mixing from the Kopfpoti trimmers.
Self-Oscillation
Push the Regeneration knob past unity for authentic self-oscillation — the same spiraling feedback the VRS-23 is famous for. Tamed by soft saturation.
DAW Sync + Divisions
Lock to your DAW's tempo with musical divisions (1/4, 1/8, triplets, dotted, swing). Or go free with the original continuous delay knob.
RTNeural Ready
Neural network slot for trained analog character models. Capture the exact nonlinearities of a specific VRS-23 unit with machine learning.
Analog Character, Digital Precision
When you turn the delay knob during playback, all existing echoes stretch and compress together — exactly like the real TDA1097 chips. The characteristic pitch glide that makes BBD delays unmistakable. No digital crossfade tricks.

Frequently Asked Questions
What is the GNM-23?
GNM-23 is a VST3 plugin that faithfully emulates the Dynacord VRS-23, a legendary BBD (Bucket Brigade Device) analog delay and reverb unit from 1981. Every circuit component is modeled from the original schematics.
How does the free trial work?
Create a free account and you'll receive a license key. The plugin works with full functionality for 90 days from first activation. After the trial, the plugin still loads but mutes after 60 seconds per session until you upgrade.
Which DAWs are supported?
GNM-23 works as a VST3 plugin on Windows, macOS, and Linux. Compatible with Cubase, Ableton Live, FL Studio, Logic Pro, Pro Tools, Reaper, Studio One, Bitwig, and any DAW that supports VST3.
Can I use it on multiple computers?
The free trial is limited to 1 device. The full license (€29) allows activation on up to 3 devices. You can manage your devices from the dashboard.
Does it work offline?
Yes. The plugin caches your license locally for up to 30 days. No internet connection is needed for audio processing — only for initial activation and periodic license verification.
What makes it different from other delay plugins?
GNM-23 models a specific physical machine at the circuit level — TDA1097 BBD chips, NE570 compander, the VCO clock generator, analog tone filter in the feedback loop. When you change parameters, the behavior is identical to the real hardware: all echoes stretch together, creating the characteristic BBD pitch glide.
