Ultrakiller is a freeware synthesizer instrument plug-in for Windows PC.
ULTRAkILLER is NOVAkILL’s latest uber-synth.
It has two oscillators, each of which offers multiple forms of synthesis. They run through two independant multi-mode filters with multiple routing opportunities. Three envelopes, two LFO and a modulation matrix make for almost endless possibilities.
The Ultrakiller plug-in is available for Windows VST (32-bit).
