Sherman Filterbank 2x2 RACK Analog Filter

via this auction

"The Sherman Filterbank 2 represents the next evolutionary step of the hugely successful Sherman Filterbank! What we originally had was a basic synth without the oscillators, allowing you to process your flat and lifeless sounds into dangerous roaring crunchy performances. The "2" is essentially the same but with an improved spec, and the kind of modular flexibility that will keep you tweaking for months."

"finally close to finished. after working on this app, i really just want to make music for awhile.
a bunch of samplers which are controlled/triggered like phases of a moon. The vertical 'serpents' create stutter effects. The horizontal 'serpents' control the sequencer(the serpent traverses the orbit into which the moons must enter). In addition, there is a cellular automata matrix sequencer which controls effects' preset-triggering. Effects include a sidechained comp, peaklimiter, filters(lopass,hipass,bandpass,notch), my FFT secretsauce, tempo-synced variable-shape amplitude cutting, and variable ping-pong delays(plus one main output mastering VST plugin option). Fed into the FFT secretsauce(a convolution effect i call RedShift) are a choice of 2 synths to convolve with output from the samplers: one is 'atebyte' which is an 8-bit emulating synth created by Jack A. Perkins and Vlad Spears(modded by me), another is 'noisul8or', a noise-based subtractive synth created by Chris Core(also modded by me).
All this makes for one monstrous spaceship console which I can currently only fly at the recruit level but soon, we will journey through the event-horizon as though the singularity was 1st nature.
