Toppobrillo Triple Wavefolder
The TWF module was designed with multi-use in mind... it is composed of three identical (with the exception of a couple features) direct-coupled waveshaping stages that can be used independently or in series, the operation is selected according to which inputs are used.
The facility for independent control over each folding stage provides multiple processing options for a variety of sources as well as more interesting explorations with timbre modulations/ frequency synthesis
Each stage can "fold" (GENTLY) an input source inward on itself as it approaches a threshold set by the panel controls and cv. For example, a sawtooth or a triangle input from a VCO can be bent into a sinewave, and beyond that- doubled in frequency, at constant amplitude... USE THEM IN SERIES AND THEY FOLD AGAIN AND AGAIN AND...some things you can do with it, under voltage control, simultaneously!
Create complex timbres from audio sources- Possibilities are really limitless. you can control each series of harmonics via the BIAS panel controls. So the overall sweep thru the folds when using the VCALL/ MANUAL controls is very flexible- and since each stage of the folding process is VC'able, you can use different modulation sources simultaneously for wild animation/ phasing/ beating with a single tonesource.
CV PROCESSOR for LFOs, envelope generators, sequencers or any control source. create multiple interesting rhythmic modulation sources from an otherwise dull one(s). useful in creating more complex, continuously variable shapes for modulation or timing.
