The Expressive E Touché SE is a MIDI controller optimized for computer use that adds a wealth of previously unknown expressive possibilities to software synthesizers. This MIDI controller reacts to the slightest touch and can recognize 4-dimensions of movement simultaneously: pressure on the front, pressure on the back, as well as movements to the left and right. Up to 8x freely assignable plug-in parameters can be controlled alongside percussive rhythms, rising and falling tones and slides/vibratos can be generated quickly. Touché SE stands out from conventional playing aids such as mod-wheels, joysticks and touchscreens thanks to its sophisticated, patented playing mechanism and haptic feedback inspired by acoustic instruments.

The Lié companion software can be used as a host for 3rd-party VST instruments. It also contains directly playable factory sounds based on the integrated UVI workstation engine. Lié can be used as a stand-alone program or as a plug-in. Only VST instruments are hosted, 250x pre-sets for popular 3rd-party software synthesizers are included.
