Read full description

Up to eight pitch shifted voices are created from vocal input or instruments. Separate algorithms for optimal shifting of vocals/monophonic instruments and for any other kind of audio. Position each voice in space ( left and right / front and back ) Modify the voice character from male to female and vice versa. Pitch shift each voice in the range of +/- one octave with preserving of formants for natural sound. Applying separate feedback delays on each voice creates complex rhythmical patterns. Features: • 8 Voice Pitch Shifter with formant correction • Optional shifting algorithm for polyphonic sounds • 8 Independent delay lines with optional sync • Spatial voice positioning • Parametric Equalizer • Integrated Compressor/Limiter/Noise Gate • Ensemble effect • Reverb effect • AudioUnit for AUv3 compatible hosts. • Inter-app audio compatible effect. • Audiobus 2 compatible with state saving. • Support for Ableton Link • Low latency live usage with mic and headphones. • Audio recorder

It supports external MIDI input and features a detailed UI with multiple keyboard options.

Highlights
  • Dual microtonal resonator banks
  • Independent pitch, volume, and modulation control
  • Advanced filter and color parameters
  • Detailed keyboard UI with note information
  • MIDI input support
  • Mix control for dry/processed signal

Read full description

resonatedo is a microtonal resonator bank audio effect for iOS and macOS. It contains two sets of resonators controlled by separate keyboards. Each resonator has independent pitch (set by EDO division value of the keyboard), volume and modulation. Each resonator is a delay with feedback that contains lowpass + allpass and bandpass filters. Each set has a common "color" parameter that changes balance between these filter sets in each single resonator. The "mix" control allows crossfade from dry to fully processed signal. UI features two independent keyboards with: • 4 – 72 keys (voices, steps) per octave, each with its own ring modulator • maximum polyphony equal to the number of voices; max polyphony is 144 voices • 1 – 4 octave range, covering the frequency range of about 8 – 4200 Hz • display with note number (from C), note name, frequency (in Hz), and deviation from 12-TET (in cents) • two sections per keyboard: upper for non-sustained notes, gliding, and velocity; lower for sustained notes and modulation rate • mute button to stop/start all sound • delete/panic button to erase all notes • glide button for smooth sweeps across keyboard frequency range • modulation on/off button • slider to set initial velocity and modulation levels • slider to change velocity and modulation rates for all notes on the keyboard proportionally and to show current velocity and mod rate levels • button to toggle keyboard visibility. resonatedo supports MIDI input from external sources to control each keyboard independently.
