LC4 Controller vs Instant Replay Pro

The exclusive LC4 Controller App gives you full control over the Yamaha LC4 Music Lab wirelessly from anywhere in the room. Music educators now have the freedom to leave their teacher station and visit students individually at their instruments to demonstrate passages, correct technique and posture, all the while maintaining the ability to operate the lab hardware wirelessly. The LC4 Controller App provides convenient access to all of the hardware functions and even adds more features. The app lets you customize and position student icons in the classroom view to match the physical layout of the instruments in the room. The in-app attendance tracker and notepad are conveniently included, eliminating the need for additional software. The LC4 Controller App even accesses the iPad’s music library and allows the teacher to broadcast songs wirelessly to the class. The LC4 Controller App is compatible only with the Yamaha LC4 Music Lab, and requires the optional LC4 WIFI KIT.

Instant Replay is a practice tool for musicians who want immediate feedback. Record a passage, stop, and hear it back right away, without breaking concentration with extra menus or setup. Designed for real practice, the app is ideal for scales, intonation, phrasing, excerpts, and vocal lines. Bluetooth foot pedal support allows hands-free control while you play, and a live waveform provides visual feedback during recording and playback. Instant Replay records high-quality 44.1 kHz AAC audio and keeps the experience simple, with no accounts, no subscriptions, and no ads.
