Here’s part two of my list: everything but effects and synths. Here you’ll find more of the strange sound generators and tweaked noisemakers, and also some useful samplers and drum machines and loop sequencers.
For MIDI/control sequencers ensembles for Reaktor, see my post about it here.
Noise Toys, Drone Makers, Grooves:
Asonis by Donovan Stringer: Hell sends its regards. Awesome ambient evolving drones.
Sort of the Rings by Program Child: Bubbles bouncing and soundscapes.
DiscoTalk II by Program Child: Some cheeky shit by Program Child, really impressive actually.
Locutus II by Dieter Zobel: Awesome Sequenced Noise maker that makes cool melodies too.
GamelaLiner by Eric Cook: Fun auto-gamelan sounds generator.
Love and Loops by Kris Keogh: Really nice auto-slicer with a bouncing ball style loop chopper thing?? Great included snaps too.
RCA Synthesizer Mark II by Mark Smart: This one completely blew my mind: An emulation of an old punch card computer system that lets you make music in the exact same way as milton babbitt if you want. Truly amazing, if completely impractical.
Spyrograph by Mary Jean-Philippe: Unique, confusing, visually beautiful, sounds awesome.
TG-8k by Nick Petty (based on Lazyfish): mental noisemaker that is easily tweakable.
xi:S (xenakis in my soup) by rachmiel: More amazingness from rachmiel.
Forest by Aleksandr Smirnov: wow. nature sounds. wtf. yessss.
Drox by Julien Caraz: Crazy glitch beat generator
mmmd1 by Martin Brinkmann: Morphing Minimal Drum Machine by
SOKOLOV CompuRhythm by Tom Zellweger: Groovebox and sound sequences
PurPurea by Gabriel Mulzer: Sampler with formant shifting and harmonizing resonators, very cool.
Cloud Splitter by Urs Baumgartner: remix of the splitter ensemble that uses grain cloud, giving it way more juicyness.
Buffeater Lite by Igor Shilov: More of an effect, a nice live granular mangler tool.
Debris Grains by Igor Shilov: A brilliant and intuitive granular sampler.
ColorStrip by Igor Shilov: More excellent granular sampling stuff.
Flakes by Igor Shilov: More awesomeness, one of my favorites. Grain sampler/sequencer.
Frame by Peter Dines: Smooth granular sampler with great interface.
SamplerPack by James Walker-Hall: Very useful samplers with great GUI, standardized across 4 types of sample modules.
White Grains by Florian Erdle: Granular sampler with nice modulation recording system
Orange Grains by Florian Erdle: More granular sampling mangling/EFX madness
