Inside the instrument are many parameters that allow you to finely adjust the sound elements of the piano, much in the same way that an experienced piano technician fine-tunes an acoustic piano for a particular artist or musical style. These parameters include pitch, volume, tonal characteristics, the extent to which the virtual “lid” is open, states of resonance from the strings and cabinet, and so on. With the Piano Designer app, you can easily control these many elements from the graphical touchscreen on your mobile device. In addition, the app includes many ready-to-play settings, allowing you to enjoy custom sounds created by world-class piano technicians. - Parameters related to lid position, strings, and hammers are listed at a glance, and can be edited and transferred to the piano easily. - Enjoy playing your Roland piano with sounds fine-tuned by famous piano technicians. - Graphically adjust the pitch, level, and tonal character independently for each of the piano’s 88 notes.
