I once did a MIDI extension for SpeechBasic to program a real time MIDI
sound sampler on BASIC for the C64, for example
$1810 LDA $DEO6
$1813 LSR
$1814 BCC $1810
$1816 LDA $DE07; read MIDI event byte, usually followed by RTS
This are 6 bytes of code, to get a MIDI data byte from the UART.
I did
$1810 LDA $DEO6
$1813 LSR
$1814 BCC $1810
$1816 LDA $DE07; read MIDI event byte, usually followed by RTS
This are 9 bytes of code, but 6 :S

Just to begin with, a C64 is a C64, where as Linux is ARM, x86, AMD64,

A comparison to the C64 is caring it to extremes, perhaps I should

So I can add, I anyway will test to use two PCI cards, at least for
MIDI, for audio would be nice too.

When I bought it, it costs between 19 and 20 €. It's much better when

a musician.
I deeply suspect the USB MIDI device now causing jitter.
