Musical inspiration at the touch of your fingertips - from doodle to zen in seconds. Inspired by the Korg Kaossilator and Moog synthesizers, Saucillator transforms mobile devices into a platform for creating, playing, and sharing digital synthesizers. Users use the touchscreen to manipulate oscillators and effects, and can also do live-looping and recording. Our goal is to be beginner friendly while at the same time offering all the deep, complex features traditional synth users love. Saucillator also now supports AUv3 so you can use many of its features in AUv3-supported host applications (tested with AUM, Loopy Pro, Garageband. Note that some host applications only support some output). A multi track looper and beat generator are available to create synth loops and synchronize a beat/click track alongside it. Loops can be modified, toggled, and added as you're playing. Users are able to play custom modular synthesizers using the x-y axes of the touchscreen. The x-axis corresponds to amplitude (volume) and the y-axis corresponds to frequency (pitch). Playback can also be looped, recorded, and EQed using a Parametric EQ. An Arpeggiator play mode also allows the touched notes to be arpeggiated, with customizable rate, pattern, gate, etc. On top of performing, users are able to create their own custom synthesizers, which consist of a custom timbre and user-defined effects. A variety of timbres are included: Sine, Square, Saw, Pulse, Noise, Theremin, "Singing Saw", "Electric Eel", and "Starslide" (among many more). These, as well as any user-created synths, can be mixed and matched at different harmonics, amplitudes, and phases to create custom sounds. Each synth has customizable fx parameters as well, including Envelope (ADSR - attack & release), Vibrato LFO (rate & depth), Tremolo, Reverb, Delay, Chorus, Distortion, Parametric EQ, and Note Lag (Portamento). We also include a Filter (low-pass, highpass, bandpass) that can be modulated using an Envelope or LFO. Custom synths can also be shared with the Saucillator community via an easy built-in sharing tool. Download other users' synths or upload your own, all from in app! Other abilities: -Choose scale: Pentatonic, Major, Minor, Blues, or Chromatic (among others). -Choose the base note for the pad. -Control the grid size. -Record to disk. -Live visualization of waveforms. -Play synths with external midi controllers -AUv3 instrument support Saucillator. I think it's the sauce, boss!
