Here comes the the crazy twin-sister of Ruismaker, designed for people who want to design their own percussion sounds from scratch. Ruismaker FM's simple, yet flexible synthesis engine lets you create anything from snaredrums, kickdrums and spacy toms to weird and unconventional percussive sounds and effects. Ruismaker FM is a unique drumsynth plugin (i.e. it does not use samples), which is coupled with a creative Euclidean sequencer when run in standalone mode. The plugin is fully AUv3 (Audio Unit) compatible: - Seamless integration with Garageband and other AU hosts - Audio Unit Instrument: making music on iOS doesn't get more convenient - Supports AUv3 Multi-Out in AUM and ApeMatrix - Each sound is modeled using authentic analog and FM algorithms; - Comes with dozens of unique customizable models - Does not use any samples; all sounds are synthesized in realtime, on the fly - Light on the CPU, so you can run lots of Ruismaker FMs simultaneously - Fully automatable parameters (requires host support) and MIDI CC controllable - Has its own preset manager The standalone sequencer is refreshingly different: - Program patterns using Euclidean algorithms - Powerful random feature and mutation probability settings per channel - Syncs with Ableton Link or MIDI Clock - Exports WAV and MIDI - Compatible with Audiobus 3 (including MIDI IN/OUT mode) - CoreMIDI In and Out - AU MIDI output for on-screen pads User manual available on Ruismaker.com

BLEASS Granulizer is an innovative granular effect processor crafted for musicians, producers, and sound designers who want to transform incoming audio signals into rich, evolving textures and immersive soundscapes. It works by slicing audio inputs into small "grains" and reassembling them through real-time modulation of different parameters that you can visualize thanks to a 3D visualizer: Modulate - Volume - Pan (represented by width in the visualizer) - Size ( = grain’s duration) - Density ( = frequency of grains generation) - Offset ( = the amount of time between record and play represented by the depth in the 3D visualizer) - Backward/Forward Playback Direction - Shape ( = grain’s envelope, represented by the height dimension in the visualizer) - Warmth ( = strength of the distortion applied to the grain) - Tune ( = grains can be pitched up or down according to different modes: “Fine” / Chromatic / Major / Minor / 5th / Major 7th / Minor 7th / Octave. The amount of randomization can be set with the “dice” knobs. Density, grain size, and offset range can be freely synced or beat synced to the host’s tempo. Touching and holding the visualizer modifies pan and density. BLEASS Granulizer takes up to 4 sources from different busses as inputs (compatible host required such as AUM). When multiple busses are on, each grain is randomly extracted from one of the available sources. BLEASS Granulizer is your unique granular texture effect for reshaping any audio source into a dynamic granular soundscape in ways you've never imagined.
