Examples

Before using amidi, it is important to disconnect all ALSA MIDI connections of the port to be used. Then ask amidi for all available ports:

   amidi -l

   hw:2,0,0  MidiSport 8x8 MIDI 1
   hw:2,0,1  MidiSport 8x8 MIDI 2
   hw:2,0,2  MidiSport 8x8 MIDI 3
   hw:2,0,3  MidiSport 8x8 MIDI 4
   hw:2,0,4  MidiSport 8x8 MIDI 5
   hw:2,0,5  MidiSport 8x8 MIDI 6
   hw:2,0,6  MidiSport 8x8 MIDI 7
   hw:2,0,7  MidiSport 8x8 MIDI 8
   hw:2,0,8  MidiSport 8x8 Control^

\ Ensure you have disconnected the ports you like to use using aconnect or a graphical replacement like the ones found on AlsaMidiPatchbays.

\ You can send a sysex file to the port hw:2,0,3 of the example above by executing the following command:

\

   amidi -p hw:2,0,3 -s BankA-Singles.syx

You can send a manually entered sysex command by typing them as hexadecimal code:

\

   amidi -p hw:2,0,3 -S "F0 00 20 33 00 00 01 07 0F F0"

\ You can record incoming sysex data to the file Sysexdump.syx using the following command:

   amidi -p hw:2,0,3 -r Sysexdump.syx

Start the dump using the controls of your device. Press Ctrl - C as soon as the dump is completed.

\ You can also ask most devices to send the desired content using a sysex request command. To do so, open two shell windows. In the first one, tell amidi to record the incoming sysex data as shown in the example above:

\

   amidi -p hw:2,0,3 -r Sysexdump.syx

In the second one, tell amidi to send the desired sysex request. You can do so by sending the request manually...

\

   amidi -p hw:2,0,3 -S "F0 00 20 33 00 00 0F 01 10 F7"

or via sending a matching sysex file containing the matching command:

   amidi -p hw:2,0,3 -s RequestSingleBank.syx

\ After the transmission is completed, precc Ctrl - C in the first shell window.

Info from mailing lists

A snippet from the LAU mailing-list:

I'm trying to upgrade the software version of a Tascam DM-24 digital mixing consol using amidi. The command is: amidi -p ```hw:1,0,1``` --send=flash.mid

Answer: amidi does not support SMF .mid files. Use aplaymidi instead.
