Raspberry Pi 4 8GB, serial ttyAMA0 MIDI, USB3 memory stick, HifiBerry Lite DAC, 16x2 LCD, harpsichord sample set, Arturia Keystep as MIDI source.

Consistent 9ms latency (yes, nine milliseconds)! Measured between end of MIDI On bytes and start of sample playback using the Korg NTS-2 oscilloscope.

This is really nice work. Thank you for making this available.
