UC4 as successor of the UC3 is a universal controller for all kinds of midi controllable hard- and software.
The all-rounder has 8 push-encoders without detents, 9 faders and 8 buttons, all switchable to 8 controller groups that allow to control a total amount of 264 control parameters. A 4-digit-display and 8 leds show the current values of all controls.
Various kinds of midi commands like program change, pitch bend, aftertouch and control change in relative and absolute mode with different acceleration amounts are possible. All these properties are fully programmable on the devices very fast and easy for each control separately.
The encoders can work as high resolution 14bit controllers too (control change or pitch bend) which makes them suitable for sensitive parameters like resonating filter cutoffs or similar things.
Use the internal 18 setups to save your individual settings. Backup and restore of all settings by sysex dumps is possible too.
The factory settings are perfect to control music and video software products out of the box if they are freely assignable. So any additional device programming isn’t necessary for many applications
The little box is also a great extension for your Ableton Live setup.
There you can control all the continues parameters like track volumes, rack macros, send amounts, track pannings and switchable patameters like clip launch/stop, mute, solo, rec arm, monitor and track select. A special control surface script for Ableton Live 8/9 with all necessary mappings is enclosed in the package. With that script you can also use two UC4 devices to control up to 16 tracks simultaneously.
