About this app

Create and play your own custom synthesizers and instruments!

Inspired by the Korg Kaossilator and Moog synthesizers, Saucillator transforms mobile devices into a platform for creating and playing 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.

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.

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, Delay, 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

Special thanks to Garrett Langley (http://dribbble.com/glangley) for helping with design and general usability.

Absolutely incredible, fun, and amazing audio sketch pad. The built-in looper is a brilliant addition. I have spent serval mornings coming up with ideas while having coffee. This synth can tap into early electronic music, think Forbidden Planet. Admittedly, I'm new to the synth app world on Android, however I have yet to find another app that can loop and generate ideas so quickly and easily. I really like creating from a few simple items. This Synth really fits that aesthetic!

Great functionality but oddly poor performance, unpleasant latency, and laggy waveform (even after tweaking settings). My phone is decent but it feels like the whole app is throttled down. Not just the DSP but the response of the grid itself. Other sound apps on my phone like random rhythm trainers and virtual pianos have seemingly perfect latency and response.

hey just letting you know we just launched an update that uses low level audio apis to drastically cut down on latency! thanks for the suggestion

Lots of fun, sounds great & pretty useful as a musical instrument. A reverb & maybe some other effects would be useful. It would also be useful to be able to minimise the synth's settings & use just the keyboard pad in portrait mode, and thus increase the note range. The looper is useful addition but can be tricky to use. I found it hard to record the initial loop without gaps at the start & end. To overcome this I recorded an initial blank loop of the length I wanted & then added the actual

thanks for the feedback! we just added some exciting new fx in the new version (tremolo, distortion, EQ), but reverb is a good one and on the short list for up next.

What’s new

- Massive performance and latency improvements. Total rewrite of the processing engine to use native audio SDKs. (Android only - iOS latency has always been great)
- Add setting for showing note names on the pad
- Add quick share option when you upload a synth to the community.
- Add Instagram link (follow us - we're new! @Saucillator)
- Fixed bug crash related to midi input race condition
