About this app

Turn your Android device into a powerful, customizable control surface for music, video, digital art, and more.

Syntien 2 recognizes a variety of input sources, including touch, movement, and sound, and converts them into data for your creative work. Syntien 2 can connect to other devices and software via MIDI, OSC, and BLE.
It comes with all the standard controls you'd expect -- buttons, labels, sliders, knobs, etc. -- plus a unique set of tools that go far beyond the basics.

- Use an adjustable, resizable Keyboard control to send MIDI note and velocity data, in addition to pitch bend, expression, and more.
- The Touch Pad control takes full advantage of your device's multi-touch capabilities. Track five touches independently on a phone, and even more on a tablet. Transmit data including position, speed, and number of touches. Use a stylus like an S Pen to send highly-expressive data with pressure and tilt sensitivity.
- The IMU control uses data from your device's accelerometer, gyroscope, and magnetometer to transmit your device's acceleration, rotation, or nearby magnetic field strength. Tie the device rotation to a smooth, continuous sound, or trigger interesting gestures with changes in acceleration.
- Use the Level Meter to track audio input levels, and use the Pitch Detector control to detect pitch.
- Transform and scale outputs directly in Syntien 2 without any complex scripting!
- Connect controls to each other using Macros. Use buttons to toggle a Keyboard's sustain pedal, set up a Slider to modulate the frequency of an LFO, and more!
- Create your own interfaces and modify the behavior of controls in-app, on any Android phone or tablet, without the need for a separate desktop editor! You can use one of the built-in presets, duplicate one for a solid starting point, or build your own from scratch. Place and resize controls exactly how you want them using intuitive drag-and-drop gestures.
- Modify controls mid-performance by sending data from your computer to Syntien. Incoming OSC messages are displayed on the screen and color-coded, so you'll know exactly what messages Syntien is receiving and whether or not they're being interpreted.

Now on Wear OS: use your watch as a standalone control surface -- no phone required. Build an interface on your phone or tablet, then send it straight to your watch over local Wi-Fi. On Wear OS, Syntien 2 connects via OSC and BLE (MIDI is available on phones and tablets only).
