The addition of a mobile app that can act as a stand-alone tuner as well as a hardware controller makes the new HD-300 a complete package that can not only make a teacher's job easier but also help their students play "IN TUNE, IN TONE, IN TIME and at the CORRECT VOLUME."

• Record ensemble performance and play it back for immediate feedback
• Simplified user-friendly interface
• Pre-loaded with 167 musical examples so that students can hear chord progressions, rhythmic exercises and more
