[linux-audio-user] sending program change to alsa

Hi I need a program that will allow me to send predefined program changes to alsa clients. I imagine something like a chain of programs, grouped together in songs, grouped together in sets, grouped together in bands. Anyways, is there such a program outthere? I'd prefer text-based, and shortcut driven... If not, could anyone point me in the right direction of some documentation on how to write such a program, esp how to register as an alsa-client and exactly what should be send out how for it to be program change. I'd like to write in python, if possible... Thanks in advance. -- peace, love & harmony Atte http://www.atte.dk
