Then I have tried aseqdump, but the two tools (aseqdump and gmidimon) don't give me the same informations. gmidimon give me a number of controller (ie 176) and the other give me a port number (ie 80). I want to know this information in order to use my midi units in ecasound but it doesn't work, I will send an help request to the ecasound list about the confuse (for me) midi implementation.
