App Description
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)
