MIDI messages getting lost, stuck notes

[jedgarpark]

I am still getting stuck notes when NoteOff messages get missed. with this example https://github.com/adafruit/Adafruit_CircuitPython_USB_Host_MIDI/blob/main/examples/usb_host_midi_simpletest_rp2040usbfeather.py if i play three or four note chords rapidly one or more NoteOff messages seems to be missed.

What devices are you using?

I've tested with two different MIDI keyboards- Arturia Keystep and Akai MPK Mini plugged into the Feather RP2040 USB Host. Output to a couple of different MIDI synths over UART, the 1010music nanobox fireball and the KORG NTS-1.
I've also tested by sending the MIDI out over USB to my Mac and watched the messages with MIDI Monitor as well as playing software synths VCV Rack, Helm, and Vital.
