Noises is an experimental instrument with a playful and inspiring interface, designed to bring a vast world of noise into your music and audio production. Available as AUv3 and Standalone. Noises is the fourth plugin we developed together with German composer and “that guy with the sweaters” Hainbach. He crafted hundreds of recordings of rare vintage measurement and tape equipment, analog synths, strange field recordings, electro-acoustic and magnetic field experiments, and more in his lab to create this creative noise instrument with us. It is designed to be fast and inspiring to use, with a big dial at its center inviting you to search for sounds and a sequencer to make them music. This results in a minimum of clicks for a maximum of sound.

Hilda is a Complex Oscillator Monosynth, inspired by the most interesting aspects of both west-coast and east-coast synthesis techniques. You'll find a wave folder, lowpass gate, and audio-rate modulations, but also a 12-mode filter and traditional VCA circuit. All parts of the instrument are carefully circuit-modelled to sound as analog (or digital, where applicable) as possible. It's like a best-of-all-worlds semi modular synth, but without the patch cables. The unique mix of different synthesis components adds up to a unique sounding electronic instrument, which can be used as a playable synthesizer, a MIDI sequencer and an audio effect for external audio - or any combination of those three. - Full Audio Unit compatibility (AUv3 instrument, audio effect and MIDI processor modes supported) - Universal design (iPhone and iPad; iPad Air 2 or higher recommended) - Built-in analog style 16 Step MIDI Sequencer with custom scales - 12 mode filter, based on the Oberheim Xpander design - Drone mode lets you [partially] bypass the VCA/LPG and just go with the flow - DIY Lo-Fi digital delay circuit emulation - Live pads with effects that can be triggered via the UI (or via exposed AU Parameters) - All synth settings exposed a AU Parameters (for automation and MIDI learning in your host of choice) - MIDI Processor plugin mode disables synth to save CPU - Carefully handcrafted by yours truly, to capture the essence of my love for tinkering and experimenting with sound :-) Find the user manual on ruismaker.com
