[linux-audio-dev] Alsa /dev/sequencer stuff

Hi all, I was wondering the following: In my app (RTMix) I will be soon implementing multiple midi-input device opens, so that the app can be controlled from as many of the midi controllers simultaneously as possible. One way of devising this was to design a separate thread for every open device (using raw midi /dev/midi etc., although I will be re-implementing that to use ALSA devices directly). However, this might not be the most elegant way of doing this, so what I was wondering is how does the /dev/sequencer correspond to this issue? I mean, does it work the same way like addressing the raw midi ports, are the message formats the same, and most importantly does one SINGULAR /dev/sequencer encompass all of the midi ports that are currently available? I would greatly appreciate any help on this issue, as well as some code examples. Thank you! Sincerely, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico
