Solution Introduction Scenario one: The stave file downloaded by the mobile phone or PAD can be sent to the electronic musical instrument loaded with ALX420 through BLE MIDI for performance. In special scenarios, the effect of automatic musical instrument performance can be realized. Scenario two: Music played on electronic musical instruments can be transmitted to mobile phones and PADs through BT audio, which can quickly realize post-synthesis processing of music. Solution Advantages Equipped with ALX420A module, all kinds of electronic musical instruments can be connected with application management electronic equipment to realize two-way transmission of audio data. It supports BT A2DP(SINK+Sourse) and BLE MIDI, with strong transmission stability and fast speed, which can meet the needs of various performances.Solution Architecture |
