Hey hey,
I wonder if the ALSA sequencer system buffers MIDI events or if it is my
hardware.
When I start a synth and play something or turn a knob and then connect it to
another hardware synth, I often hear a burst of notes or find that some CC(s)
have been sent.
If that is a feature of the ALSA SEQ, can it be cleared?
Best wishes and thanks,
Jeanette

same thing here, but only after booting the system. the first client
to connect to the h/w input devices is showered with a burst of
accumulated events. after that, everything's fine until the next
system boot.
has been like that for years but seemed too benign a problem to
bother. :)

ALSA can buffer MIDI data, but only as long as some program has opened the device.
A USB MIDI device might actually have its own buffer.
can it be cleared?
amidi --port "..." --dump --timeout 0.1 > /dev/null

Thank you Clemens!
I mostly have USB MIDI devices, so this should solve
it.
