midiminder & midiwala

midiminder: an ALSA utility to keep your MIDI devices connected
midiwala: a tool for managing connections

The problem

• Using aconnect to reconnect your devices and your software gets old quick.
• If you power cycle a synth... you've got to aconnect it again.
• Bandmate "helps" by unplugging a USB cord to untangle it and plugs it in again: Now your controller is disconnected.

The solution

midiminder takes care of this:

• It tracks what connections were made between ports, and automatically reestablishes those connections when ports reattach to the system.
• You can specify a profile of things to connect and then tell midiminder to reconfigure your system to that profile in one command.
• The whole desired connection state is persistent, even across system reboots, so that the configuration is quickly restored once devices power back up and applications are restarted.

A bonus

midiwala provides an interactive terminal interface for looking at, and modifying the connections on your system. Try it... you won't regret it!

It also includes all the command line functionality of aconnect (list, connect, disconnect), but with very readable output, and improved syntax for specifying ports.
