Acorn Instruments Masterkey 25

The Acorn Masterkey 25 is a light-weight portable synth style MIDI keyboard controller with assignable controls for mapping to popular recording software. Well built and robust, the Masterkey 25 can easily be transported around for making music on the go, or can be used in the studio as a level entry DAW controller.

The top of the Acorn Masterkey 25 features a 25 key velocity sensitive synth-style keyboard making it the perfect midi controller for making music on the go.

On the left hand side of the usb keyboard is the Masterkey 25's control section. You get 4 smooth assignable rotary knobs which can be mapped to any control such as PAN, reverb delay or any other effect within your DAW software.

The large slider fader is perfect for mapping to volume controls of individual channels while the LED screen indicates the position of the parmeters in use with a 3 digit red display

The three buttons below the screen are for shifting octave up and down with an additional edit button for edting drums or instruments. These controls can be over written and mapped to popular software functions such as stop, play and record.

To finish off the control section of the Masterkey 25 you get two jog style wheels for adjusting pitch bend and modulation.

The back of the masterkey 25 has a class compliant USB port for connecting the keyboard directly to a computer. Class compliant means the masterkey does not require a driver so you plug it in and start making music straight away. The MIDI keyboard powers directly from your computers USB port so no need for additional power supply.
