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).  Because it is based on the Behringer UMX610, it has the advantage over the M-series equivalent of neater "diving board" white keys. This allows the keyboards to be nested closer together, in accordance with normal organ building practice, reducing the stretch when playing on the higher keyboards (all the more noticeable when there are four keyboards).There is currently less difference in touch between the two types of stack than there was in the past. In any case, touch is a highly subjective matter, so if in doubt, the best policy is to try both types of keyboard before deciding. The other main advantage of the US4 over the MS option is that the pistons are better quality and larger, and the cheeks are wider and profiled. . The US4 is also available without cheeks, please contact us for price.

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.
