No. There are two layers of routing. The hardware routing specifies how the (hardware) MIDI connectors are connected to each other and/or to the ports made available by the driver. ALSA's routing specifies how these (software) ports are connected to each other, and/or to applications. > (UM-550/UM-880) > In general, is there any way to control this interface in software under > Linux? Chris Pickett already mentioned this is possible by sending SysEx's to the control port. There isn't any point-and-click utility for Linux, but it wouldn't be an overly intricate job to write one. > how stable are these cards (the ones that require your loader) > under Linux?

I don't have any M-Audio device, but from what I've heard, all MidiSport devices work just fine. > Do you see any problems in the future, like - your loader not working > anymore under future versions of the Linux kernel, etc. I don't foresee any incompatible changes to the kernel.
