About

Syntien 2

Read full description

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. â€Ē Use an adjustable, resizable Keyboard control to send MIDI note and velocity data, in addition to pitch bend, expression, and more. â€Ē The Touch Pad control takes full advantage of your device's multi-touch capabilities. Track multiple touches independently. Use a stylus like an Apple Pencil to send highly-expressive data with pressure and tilt sensitivity. â€Ē 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. â€Ē Use the Level Meter to track audio input levels, and use the Pitch Detector control to detect pitch. â€Ē Transform and scale outputs directly in Syntien 2 without any complex scripting! â€Ē 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! â€Ē Create your own interfaces and modify the behavior of controls in-app, on any iPhone or iPad, without the need for a separate desktop editor! Place and resize controls exactly how you want them using intuitive drag-and-drop gestures. â€Ē 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. Works with Ableton, Max/MSP, SuperCollider, TouchDesigner, and any MIDI- or OSC-compatible software.
