Re: [alsa-devel] Slow/piecewise send of sysex?

I'm using amidi --send-hex to send data to a Commodore 64 via a CLab MIDI interface. The problem is that even with 100 bytes the probability of a buffer overrun is about 30%. I didn't find a way to throttle the send speed.

.syx files do not contain timing information.

In alsa-utils 1.1.3 or later, amidi has an option to insert a delay between F0...F7 messages.

But if your MIDI devices does not handle MIDI speeds at all, you have to put the SysEx data into a .mid file with the proper delays.

I would like to be able to send the data a few bytes at a time in a simple shell loop.

Binay data in the shell is not easy. Why not write a tool in some other language?
