Hi there, This may be a very simple question, I am not sure. I am hacking on a buzz-like tracker, aldrin. It is written in Python, but the heavy lifting is done by libzzub, which uses portmidi for midi implementation. At the moment, midi in devices can be selected, midi out are a bit buggy, but I think that should not be too difficult to sort out. The main problem which I would like help with, is that the midi inputs and outputs from aldrin do not show up in with aconnect -lo or -li at all.. Is it possible to get portmidi to work with alsa correctly in this way, or are midi connections always handled within the program, connecting to alsa devices, but invisible to aconnect? The source for both projects is at: http://trac.zeitherrschaft.org/aldrin/browser http://trac.zeitherrschaft.org/zzub/browser All the best, James
