US4 - Four Keyboard MIDI stack

 

 US4 Peter

The US4 is a four-keyboard stack constructed as a single unit, a higher spec version of the M-Series equivalent (MS2 + MS4B).   There are three main advantages compared to the M-Series equivalent:
- the keyboards are more closely nested
- the pistons are better quality
- the cheeks are wider and profiled
Since the start of 2021, both types of keyboard stack have utilised the M-Audio Keystation 61 Mk3, so there is no difference in touch.

The stack plugs directly into the USB ports of your computer, or a USB hub. Use the stack on its own, or combined with a MIDI pedalboard. Can be placed on a table, desk or other convenient surface, or built into an existing console.

The stack is guaranteed for one year.  See Our Selling Policy for the terms of our guarantee.

Pistons
The 32  pistons can be configured to do almost anything in Hauptwerk. Most obviously they can be used as combination pistons, but they can also carry out menu commands. Particularly useful ones are to advance the registration sequencer, or to start and stop the built-in recording. The pistons are not numbered, but they are grouped into fours for ease of identification.

 MIDI output channel
MIDI output is on channel 1 for all keyboards and pistons,
