I'm trying to use amidi to save sysexes from my USB keyboard controller. I initiate the sysex by hitting the buttons on the controller. Data is definitely getting sent by the keyboard controller, ALSA is receiving it, and aseqdump shows it, but amidi isn't saving it, and says it isn't receiving anything!

What am I doing wrong here?

$ amidi  -p hw:1,0,0 -r keystation-defaults.syx -t 1
	(nothing happens, just sits there, until I Ctl-C it).


$ amidi  -p hw:1,0,0 -d
	(also, nothing happens, just sits there, until I Ctl-C it).

But...

$ aseqdump -p 20:0
Waiting for data. Press Ctrl+C to end.

It's definitely the same device:
