Amazing Noises has released Pulsor, a virtual synthesizer instrument for Max for Live.
It is essentially a monophonic synth that produces glitching/pulsing sounds and complex rhythmic soundscapes thanks to its odd circuitry.
It can also create evolving lead synth sounds, monophonic bass timbres and many other unexpected noises.
Pulsor is available for purchase for the introductory price of 15 EUR until July 20th, 2014 (regular 20 EUR).
