Ghost Time has shared a series of user oscillators & effects for the Korg Prologue synthesizer (they say they should work with the Minilogue XD & NTS-1, too).
Warped, demoed in the video above, is a lo-fi oscillator, inspired by the sounds of Boards of Canada.
Sneq, demoed above, is described as an experimental oscillator, less focused on tonality and more on rhythm.
Each note can play a rhythmic sequence, which you can customize with controls for sequence length, offset, note probability and more.
Warbly is a user effect that adds an unstable ‘warble’ to your patches:
Other Ghost Time oscillators include Step, a per key arpeggiator; Lapse, a stacked-LFO drone generator; and Slinky, a modulated delay effect.
The Ghost Time user oscillators and effects are available now with a ‘name your own price’ pricing.
