Bit Splitter vs VAPolyEnsemble

BIT SPLITTER A bit-plane manipulator. The input is scaled and quantized to an 8-bit value, then a single bit-plane of that value is used to reshape the signal. Where a bit crusher reduces resolution and hands back a degraded copy of the sound, the bit splitter operates on one specific bit and can either output that bit on its own, use it to gate the input, or mask the signal down to a chosen number of bits. MODES ISOLATE Outputs the chosen bit-plane on its own as a bipolar square wave. The most-significant bit behaves like a sign comparator, producing a hard square that tracks the waveform; lower bits flip more often as the amplitude moves, giving increasingly noisy, aliased fuzz. This is the most literal reading of splitting a bit out. GATE Passes the dry input only while the chosen bit is high, and mutes it otherwise. The signal is chopped by its own bit-plane, producing glitchy, rhythmic gating that still carries the source material underneath. MASK Zeros every bit below the chosen one and reconstructs the result to audio. This is a bit-depth reduction in which BIT sets how many low bits are discarded: at 0 the signal is untouched, at 7 only the most-significant bit survives (1-bit). Closest of the three to a classic crusher, but with arbitrary bit selection. CONTROLS BIT In Isolate and Gate, selects which bit-plane is used, from 0 (LSB) to 7 (MSB). In Mask, sets the lowest bit that is kept, so it acts as a resolution control. Lower bits track fine detail and toggle rapidly; higher bits track the gross shape of the waveform. Range: 0 to 7 THRESH Input drive into the quantizer. The signal is divided by this value before being mapped to a byte, so lower settings push the signal harder into the 8-bit range (clipping into it sooner) while higher settings keep it quieter and more centered. It changes which bits are active for a given input level, and so reshapes the character of every mode. Range: 0.01 to 2.0 MODE Selects the bit-plane operation: Isolate, Gate, or Mask (see above). Switching mode changes what BIT means, so the two are best adjusted together. MIX Controls the balance between the unprocessed (dry) input and the processed (wet) output. At 0% only the dry signal is heard; at 100% only the processed signal passes through. Intermediate values produce a linear crossfade, useful for blending the harsher modes back under the source for parallel-style processing. Range: 0% to 100%

VAPolyEnsemble features a unison oscillator that can produce seven detuned saw, pulse, or triangle waves per voice. It is followed by a stereo resonant low-pass filter, a stereo resonant high-pass filter, and a stereo amplifier. VAPolyEnsemble operates as a stand alone or as an AudioUnit Extension (AUv3) for iPhone, iPad and Mac. Stand Alone supports Ableton Link, MIDI and audio file export. Built-in Effects include delay, chorus, flanger, reverb, eq and compressor. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac. Main Features Unison oscillator that can produce seven detuned saw, pulse, or triangle waves per voice. Stereo VCF and Stereo VCA. Low pass Filter is modeled on cascaded OTA -24dB per octave low pass filter circuit. 3 channel analog style step sequencer. - Maximum 8 voice polyphony. it depends on performance of the device it is running. - Built-in effects and piano roll sequencer. - Audio Export.

Support iCloud Drive to share project files between the platforms. - Support MIDI Foot Pedal (CC#11, CC#64) - MIDI CC Settings are saved. It will be recovered when the app launched in the next time. - Selectable UI Color. - Font size for title of controls are adjustable. - Factory Preset 128 - Effects Preset 40 System Requirements - iOS 17.0 or later - Devices with Apple Silicon are recommended. A13 Fusion or above is highly recommended. - AudioUnit Extension (AUv3) requires host application which support AudioUnit Extension. - AudioUnit Extension is supported by Apple Logic and Apple Garage Band on iOS and macOS. For any other DAW, it depends on the application and some of them don’t support AudioUnit Extension. - Sound may be distorted if CPU of the device doesn't have enough power. If it happens reduce number of voices.
