### THIS IS A DEPRECATED PRODUCT. Get KQ Unotone 26 instead. ### If you bought this app recently, you can request a refund. Not just a Toy Synthesizer. Good for make noise. Tweaking knobs is really fun! Double-tap to adjust the knob. - Included: 2 Oscillators, LPF, Delay effector, Ribbon controller - Not included: Envelope Generator - The pitch changes when you tweak Delay Time. - Also acts as a effector. - Audio Unit v3 is supported. - Audiobus is supported. - Inter-App Audio is supported. Attention: You must use either "Instrument" or "Effector" when you connect it via Audiobus or Inter-App Audio. Also Launching the app may be necessary after connection if you use iOS 12.4. Try reducing PEAK or setting FEEDBACK to zero when the sound does not stop or is silent. Delay is not turned off even if TIME is zero. Instead set FEEDBACK to zero.

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.
