When the instrument is turned off, any unsaved parameters or songs are reset. UPDATING THE SOFTWARE The system software of your C-720 can be updated. From time to time, Korg might release new versions including bug fixes and new features. Please check our website for more information.
The USB port also carries MIDI data, so that you can connect the C-720 directly to your personal computer with a single ca- ble and without the need of a dedicated MIDI interface. A ded- icated KORG USB MIDI Driver is freely available for full use of the C-720’s MIDI features.

Temperaments In addition to the Equal temperament, the C-720 allows you to select nine alternative temperaments, for historically accurate performance of classical music, or experimenting. When se- lecting an acoustic piano sound, the typical Stretched Tuning is automatically selected. Adjustable pitch The Transpose function lets you change the pitch of the piano, and the Master Tuning function allows you to make fine tune adjustments.
