• License: MIT License
• Description: Open source MIDI to USB converter hardware

Requested PID Allocation:

• 0x6193: MIDI2USB Converter(for MIDI1.0)
• 0x6194: MIDI2USB Converter(for MIDI2.0)

Justification:
This project provides an open source solution for converting MIDI signals to USB, filling a gap in affordable MIDI conversion tools. The hardware design and firmware are fully open source under MIT license.

Thank you for your consideration.

I notice there's a conflicting PID allocation request (#65 ) that was submitted earlier.
I'll close this PR temporarily and resubmit with updated PID numbers to avoid conflicts.

Thank you for your patience.
