BLE Client Problem with Adafruit TinyUSB

Hi. I want set the midi output to adafruit tinyusb host but get compile error. the code:

MIDI_CREATE_INSTANCE(Adafruit_USBD_MIDI, usb_midi, MIDI);

This library was developed prior to Adafruit_TinyUSB and only does MIDI - the Adafruit lib does much more. Why do you want to mix them?

thanks for reply. I want to get BLE midi from a device and send it to ESP32 usb host for android.
