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 Delay is the ideal tool for adding depth, movement and interest to your mixes. Whatever style of music you produce and whatever instruments you work with, its versatility and ease of use help you achieve perfect results with the minimum of fuss. Echoes are just the starting point. The integrated frequency shifter and dual filter give you deep control over the character and sound of every repeat, so you can achieve with a single plugin sound effects that would otherwise require a complete plugin stack and complex routing. BLEASS Delay also includes three LFOs, one each for the delay engine, the frequency shifter and the filters. As well as classic modulation effects such as chorus and flanging, these dedicated LFOs are ideal for creating exciting sound effects and epic, constantly-shifting soundscapes. FEATURES • Delay time synced to your host tempo (note values, including triplets) or set freely in milliseconds • Ping Pong mode with adjustable stereo width • Frequency shifter applied cumulatively to each repeat • Low pass and high pass filters: drag on the graph to set cutoff and resonance • Three LFOs, each with depth, rate and stereo phase offset up to ±180° • Feedback from a single echo to infinite repeats • Dry/Wet control • Preset manager with factory and user presets, plus a preset generator • Clear single-screen interface on iPad and iPhone WORKS WHERE YOU MAKE MUSIC BLEASS Delay is an AUv3 plugin.
