I would greatly appreciate some help on this 🙏

I'm working on an audio project that I need to use PJRC'S AUDIO LIBRARY and ADAFRUIT'S TINYUSB LIBRARY.

1) I need Adafruit's TinyUSB Library in order to easily drag and drop files to the MicroSD card from computer onto project via usb cable plugged into dev board.
2) I need PJRC's Audio Library to play polyphony wav files off of a MicroSD Card via a headphone jack triggered by button presses.

Here's what I'm noticing:

I'd prefer to use use a Teensy (because they're the best) with the Audio Shield, but Teensy doesn't support Adafruit's TinyUSB Library And to my knowledge, there is no easy way to drag and drop files to Teensy's MicroSD card by reading it as Mass Storage Device (MSC) via a USB cable from the Teensy to the computer. I'm in the Apple OS ecosystem, so MTP isn't really compatible with Mac... at least I don't think so?

If I use Adafruit's Feather M4, I can't us PJRC's Audio Library to do polyphony audio Or at least I think I can't? I haven't been able to find a parts to do it...

What are my options for a dev board and "audio shield" that is compatible with both of those libraries or features?

Are there any options for getting files to a MicroSD card without physically plugging it into a computer?

I'm near the end of a project I've been working on for a long time. Been doing it on a Teensy 4.0 with the Audio Shield, but I really need my project to be able to have a way to get files to the MicroSD card other than removing it from the project and plugging it into a convertor each and every time. Adafruit's Boards have the MSC feature I need, but not the power and audio capability that Teensy has.
