7.Support the integration of USB-MIDI and Bluetooth instruments
Digital musical instruments (such as keyboards and blow pipes) can be connected to mobile phones through USB-MIDI ports. After selecting the connected instrument in the "Select USB Instrument" section of the APP, you can play the performance of the digital instrument through the designated channel tone on your phone. Due to the fact that mobile phones often only have one USB port at the bottom, USB can only connect to one digital musical instrument at a time.
If the instrument provides Bluetooth MIDI output, it can also be connected to a mobile phone. After selecting the connected instrument in the "Select Bluetooth Instrument" section of the APP, you can play the performance of the digital instrument through the designated channel tone on your phone. Bluetooth can simultaneously connect multiple digital musical instruments for ensemble performance. Ensemble requires higher hardware configuration for mobile phones, and it is recommended to install this app on newer phones.
8.Provide preview of timbre effects
The APP provides 5 classic music pieces, which can be selected through "Sound Preview Music" in "Sound Effects" ->"Other". On the "Channels" page, you can adjust the tone settings of each channel and preview the effect of that tone by playing a selected song.
9.Provide multiple channel tone presets
The APP has more than ten preset channel tone settings, including piano, organ, saxophone, guitar, bass, string, brass, woodwind, flute, Chinese plucked string, Chinese wind playing, percussion, chromatic percussion, and other ethnic instruments, making it easy for users to select the current channel tone settings. Users can also add their own presets, save their favorite sound effects separately, and activate them with one click.
