Drone synth for Norns/Fates heavily inspired Moffeenzeef Stargazer. Much appreciation goes to Moffeenzeef for creating the Stargazer and kergener for their SCgazer Supercollider engine which serves as the backbone for this Norns version.
The hardware Stargazer has some impressive drone capabilities, which are emulated here:
- dual wavetable oscillator with 90 arbitrary waveforms
- sub-octave, detune, volume for second oscillator
- 2 resonant filters
- sample rate reduction
- bit rate reduction
- 3 wavetable LFOs
- CMOS distortion with 100x gain
Here’s brief (albeit limited exposé of all the sonic possibilities available) demo highlighting how it can be used with and without an external controller.
Stjörnuíþrótt can be installed via Maiden’s project manager.
After install or update
SLEEP is required, because Stjörnuíþrótt installs a new engine.
The params for Stjörnuíþrótt are vast. As with the original Stargazer knob twiddling and experimentation are encouraged. However, here’s a table of all the controls and their values (also listed within the params menu).

- Fixed sub-octave and wave selector bugs
- Fixed order of UI elements
- Added LFO res
- Added Midi passthrough
- Added parameter randomization
- v1.0.0 Initial release
1 Stjörnuíþrótt is a crazy name huh? It’s old Norse for Astronomy.
