Syntien 2
Read full descriptionHide 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. âĒ Use an adjustable, resizable Keyboard control to send MIDI note and velocity data, in addition to pitch bend, expression, and more. âĒ 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. âĒ 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. âĒ Use the Level Meter to track audio input levels, and use the Pitch Detector control to detect pitch. âĒ Transform and scale outputs directly in Syntien 2 without any complex scripting! âĒ 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! âĒ 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. âĒ 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.
