YAMAHA HD-300 Harmony Director 61-key keyboard for rhythm and harmony practice

Yamaha YAMAHA HD-300 Harmony Director 61-key keyboard for practicing rhythm and harmony In wind band practice, one of the major concerns for instructors and performers is that they spend a lot of effort trying to align the rhythm and harmony, and run out of time before they can reach the music they were aiming for. The HD-300 can quickly show accurate tempo and pitch that instructors find difficult to explain in words, and performers can efficiently develop a sense of pitch, tempo, and rhythm by practicing while listening to the sound. The HD-300 supports your performance so that you can learn the basic techniques of playing more efficiently and use your limited time to share the joy of music. [Recording function for interactive learning] The HD-300 incorporates subjective and interactive learning and is equipped with functions that allow players to actively improve. The HD-300 helps bring out the abilities of players and supports them to enjoy the joy of music even more. [Easier to use interface] -Panel design The design has been completely redesigned, so even with the increased number of functions, you can easily find the button you want to use and operate it. -User interface The touch-sensitive push buttons (tactile switches), sliders, and physical dials are used so that you can feel the operation without checking the LCD screen. [Training functions that support efficient practice] 167 JBC Band Study sound data are built in, and by using them in conjunction with the separately sold JBC Band Study, you can effectively improve your basic skills. The HD-300 plays automatically, so you can practice while listening to the correct pitch and rhythm, whether you are practicing in a part or alone, and learn more efficiently. [iOS-only app “HD-300 Assistant”] By connecting the HD-300 to a smart device with the newly developed iOS-compatible app “HD-300 Assistant” (free) installed via Bluetooth, you can easily control the HD-300 body remotely, distinguish chords, check the hum and harmony balance, and more.
