Vienna Grand Piano can be operated by any keyboard or stage piano. The newly developed MC1 controller makes the selection of piano sounds easy, and, thanks to its compact size (9 x 6 cm) and long cable (5 m), it saves space in any place. The MC1 also filters MIDI data. You can filter out program changes, volume commands, and more — just the way you want them — and then save your personal settings on the MC1. This feature makes it easy to combine the Vienna Grand Piano with any arranger keyboard. Use the keyboard or the controller to select the sound. With the mute button, the Vienna Grand Piano is easy to switch on and off as needed. The MC1 controls the amount of reverb and it provides master volume and master tune controls.
