CatStretch is a 6-voice polyphonic time-stretching sample playback instrument. It lets you ‘freeze’ a sonic character at a specified position and play it back chromatically with MIDI notes. The position of a sample can be adjusted with the ‘Scrub’ dial. It uses a phase vocoder to achieve time stretching up to total time freeze.
The phase vocoder is a tool used to perform time-stretching and pitch-shifting on recorded sounds. Its name derives from the early “vocoders” (contraction from “voice encoder”), which used a set of bandpass filters in parallel over many frequency bands, to crudely analyze and reconstruct speech. The infamous hardware vocoders of the 1960s and 1970s were based on this technology, and allowed the spectrum of one sound to be controlled by that of another, e.g. a voice. Pitch-correcting software like Auto-Tune, by now widely used in commercial music production, is based on the phase vocoder principle.
Bertha 2 is a polyphonic additive synthesizer with a few extras. With its eight tone generators, and drawbar-style control, Bertha 2 excels at producing sounds reminiscent of vintage Farfisa or Vox transistor organs. The requisite vibrato, chorus and distortion effects, along with the Leslie speaker simulation, let you conjure up all manner of classic organ tones for the garage, the arena, and the church. Going beyond the earthly realm is simply a matter of engaging Bertha 2’s microtonal mode and taking advantage of the device’s full-featured ADSR envelope – fascinating, otherworldly textures await.
