Get professional audio visualization with your AUv3 host or the standalone app. Scope transforms your audio into stunning visual displays using GPU-accelerated graphics with classic phosphor glow effects reminiscent of vintage CRT oscilloscopes and more. Featuring Scope Linear, Scope Circular, Flurry particle, Spectrum, Spectrogram, Spectrum Equalizer, 3D Spectrum, Semaphore, Sliding Scope, Loudness and Polar Level visualization modes with single and multi-channel split view, plus an Overlap option that draws both channels on one canvas in Scope Linear. Multiple color schemes (including classic phosphor green, vibrant 80s Red and Rainbow) with smooth transitions. Flurry mode renders mesmerizing smoke-textured particles with audio-reactive dynamics, inspired by the classic screensaver. Loudness is an ITU-R BS.1770 / EBU R128 meter with integrated, short-term and momentary loudness, true peak per channel, loudness range and a three-minute history against streaming, podcast and broadcast targets. Polar Level is a stereo vectorscope that plots pan position against level in dB, shows out-of-phase content in red and includes a correlation meter. All visualization modes are fully automatable parameters in your DAW. Optimized for HiDPI Retina displays with dynamic line width scaling, Scope delivers smooth 60fps+ performance for live performances, creative sound design and professional audio monitoring. Whether you are analyzing dynamics during mixing, assisting with sound synthesis or adding visual interest to your sessions, Scope provides the precision and aesthetic flexibility you need. Place it anywhere in your signal chain to visualize audio at any point, though it is typically used last to analyze the cumulative effects of your processing chain.

Solderbox is a compact semimodular synthesizer, made in collaboration with Jakob Haq. It is heavily based on Jakob's own modular rack design (which features a lot of modules made by hand). The app is designed to offer a set of modular functions that is both comprehensive and eclectic, including several tools for generative synthesis, random signals and the surgical mangling of audio waves and modulation signals. A lot of effort went into making everything sound and behave as analog as digitally possible (with the exception of the unashamedly digital Entropy lo-fi effect processor). Additionally, the built-in Instability Engine injects the subtle fluctuations simulating the effects of crosstalk, leaky signals and expired electrical components. This is a living instrument with a soul of its own. - Full Audio Unit compatibility (AUv3 instrument, audio effect) - Universal design (iPhone, iPad, MacOS AUv3) - Built-in Pulsequencer (LFO-based generative melody generator with custom scales) - 4 mode Low-pass filter (6, 12, 18, 24 dB) - 3 voice polyphony - Drone mode - Stackable patch cables - DIY Lo-Fi digital delay circuit emulation - All synth settings exposed a AU Parameters (for automation and MIDI learning in your host of choice) Find the user manual on ruismaker.com
