Summary: patch for native alsa sequencer midi support
Initial Comment: The patch allows pd to be connected to different sources and sinks of midi messages through the alsa sequencer natively. It lets pd open 1 or more sequencer inputs or outputs. Alsa midi support is selected at compile time, if alsa headers are found alsa midi support will be compiled instead of oss. All midi events work ok, i think probably raw midi does not.

reopened!
attached is an improved version of the alsa-sequencer support, that automatically connects each available device to/from pd. (note: currently it only connects if pd opens just 1 port) this eliminates the need for "external" helpers, like the [aconnect]-external, aconnect, aconnectgui or qjackctl
furthermore i found and fixed some, namely reverting the number of in and out devices.

Hmm, I can't find Guenter's fix... did it really get uploaded?

implemented a first version of runtime switching between OSS-midi and ALSA-midi. i haven't made all the various APIs switchable (as is with audio), because it deemed me too much work...

replaced s_midi_alsa.c with steve's version; this allows more than 1 MIDI output-port (or device) (read: more than 16 channels) and fixes [midiout]

i did a little tweaking of this patch and right now it works on all 8 ports of my midisport8x8, plus sys_putmidibyte is implemented, so [midiout] actually triggers midi instead of an error message. it's a bit of a hack job, but it works great for me (and hopefully you as well).
my modified version of s_midi_alsa.c can be found at http://finkla.com/steve/s_midi_alsa.c if anyone with power to update the files here on sourceforge cares to, please do, but in any case that link should stay alive for quite a while.

I didn't look closely, but I think to do this right would require actually giving a run-time choice between ALSA and OSS MIDI systems. A big job.

Here is the patch and s_midi_alsa.c file as I use it in the Debian package currently. It seems that the author of the patch does not have to time to update it, or probably he just isn't aware of problems, so take it with a grain of salt. Also we have to check for the multiple devices problem steve.long mentions.

apparently [notein] for channels above 16 works as expected, 17-32 coming from the second device and so on, but [noteout] only sends to the first device, chans 17-32 send to device 1 just like 1-16, as do 33-48, etc.

this crashes my system if i don't have an alsa-sequencer (e.g. no modules loaded)

there is a bug when no alsa devices are present (or if they can't be opened). Attached addon patch fixes the problem.

i talked to various people (e.g. fernando (of CCRMA fame) at the ICMC) and all of them agreed that it is a bad thing, that pd doesn't work out of the box with already connected alsa-sequencer devices. so i have added this autoconnector, which tries to connect all available midi-sources to the pd-in and all pd-out to all available midi-destinations.
i have done it in such way, that the autoconnection only takes place when there is just 1 port (input and output are handled separately; so if you have 2 midi-in ports and 1 midi-out port, pd will automatically send to all midi-destinations it finds; in this case, the midi-in still has to be manually connected)
currently there is no real way, how to turn that feature off (apart from requesting multiple ports, so no autoconnection takes place)
i hope this is ok.
furthermore i found and fixed some, namely reverting the number of in and out devices.
requesting 3 midi-in devices resulted in opening 3 midi source-ports (which are really midi-outs)
the patch can be found at https://sourceforge.net/tracker/index.php?func=detail&aid=1060511&gr... (i just re-opened the old thread for natice alsa sequencer support)
