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
