Question about amidi -l output

Hi,

I hope someone can point me in the right direction.

So the Ardour application uses the output of amidi -l to name USB devices. In my case I now have 3 devices all named "Boutique MIDI 1", although they are 3 different types of synth.

I already added the devices to usb-list and system-hwdb so lsusb shows up with correct synth names.

What can I do to make amidi -l show better device names? Where do these names come from? What lib or db should I look at to patch and submit?

I hope someone can help me.

Regards,

Jeroen Baten
