Ursa Major StarGate 323 Reverb
This is my attempt at a digital recreation of my Ursa Major StarGate 323 Reverb.
The ensemble is based on over 18 months of RnD, which included detailed analysis of the actual rom data, a low level emulation of the internal digital logic as well as modeling the frequency response of the analog filters.
Based on the design of the SST-282, the StarGate 323 offers eight different reverb modes, ranging from tight plates to gigantic spaces. Each mode offers a set of custom decay times, including a zero-decay setting. The zero-decay setting disables the reverb tail so that only the early reflections can be heard. This creates interesting stereo widening effects, which vary with each reverb mode. Pre-Delay is adjustable from 0-320ms and can also be used in conjunction with the zero-decay setting to create slap-back effects.

– added parameter names for midi control
– added noise on/off switch
– removed Michael Hetrick’s sample rate reduction macro
– replaced Michael Hetrick’s bitcrusher macro
– matched gain & noise levels with my hardware unit
– internal optimisations
– Happy 1 year anniversary 🙂
– Pre-Delay is now continuously variable!
– reduced CPU usage
– removed legacy 32kHz algorithm
– CPU optimizations
– updated GUI
– modulation input for the wet/dry control
– added delay time interpolation for higher samplerates
– improved anti-aliasing filters
– improved readability of the internal structure
– improved noise randomization
– improved noise modeling
– improved randomization
– improved parameter readout for Pre-Delay & Decay Time
– added the “original” tooltips
– added parameter smoothing
– added input mute & dry only buttons
– updated GUI + Rack ready
– added circuit noise
– I’ve been banging my head against the wall for four months straight just to realize that the reverb feedback signal needs to be inverted. tl;dr today the ensemble finally started sounding like my actual hardware. Enjoy!
– implemented sign inversion logic of the feedback & output taps
– adjusted internal feedback value
– fixed the comb filtering issue
This is not a VST/VST3/AU but a Reaktor Ensemble that needs to be run inside Native Instruments Reaktor to function.
Easiest way to it as an FX:
1. Save the downloaded file anywhere you like.
2. Add NI Reaktor FX (not the VSTi but the FX) to your insert section of the track in any DAW.
3. Inside the Reaktor FX, go to File-> Open and find the Ensemble file (SG-323.ism).
