I have not checked it, because I'm away from work, but
I'll try a guess here. Sometimes MIDI devices send
NOTE_OFF messages as NOTE_ON with velocity 0;
If you're not getting note offs but retriggering, that
might be the problem. 

I had a look at the new pmidi.c
and at first, the code on sensMidi() now seems to be
right, as it is picking up the whole message instead of
a single byte at a time. 

It also occurs to me that with the adoption of portmidi,
we will have to change the external midi callback 
description in the API to deal with the portmidi 
message structure instead of raw bytes.

Could someone be so kind as to send me a blow-by-blow instructions to
use virmidi on ALSA/Linux?  I really need a test world for MIDI and I
have no MIDI card on any of my Linix machines; someone introduced be
to virmidi which seems the solution as I should be able to drive
Csound from Rosegarden, but I do not understand aconnect
==John ffitch

Hi John,

I found this on google:

http://linux-sound.org/quick-toots/4-sequencers_and_softsynths/quick-toot-midisynth_howto.html

I've used this toot before to setup virmidi, though that was a while 
ago.  I assume it's still valid.

Hope that helps!
steven

Thanks Steven.  I am a little further forward but I am still
confused.  I see

client 75: 'Virtual Raw MIDI 1-3' [type=kernel]
    0 'VirMIDI 1-3     '
xenakis:~/Sourceforge/csound5> 
ans when I run csound5 with -M3 I see....

**** Pm_CountDevices()=8
0: ALSA, VirMIDI 1-0 (output)
1: ALSA, VirMIDI 1-0 (input)
2: ALSA, VirMIDI 1-1 (output)
3: ALSA, VirMIDI 1-1 (input)
4: ALSA, VirMIDI 1-2 (output)
5: ALSA, VirMIDI 1-2 (input)
6: ALSA, VirMIDI 1-3 (output)
7: ALSA, VirMIDI 1-3 (input)
**** opening MIDI device 3

and then it continues.  However it never reads any MIDI events from
VirMIDI 1-1 when I play a score in Rosegarden.  It maybe that I do not
know how to set up the Rosegarden MIDI (I am really ignorant about
MIDI -- barely understand any of the term).  Should I use a different
sequencer, and if so how/which?  I really want to get the PortMIDI
port done and this lack of testing is a pain.

Hi John,

I also do not use MIDI very much, and the last time I used virmidi I did 
not use aconnect to make connections, but a GUI application, which I do 
not remember off-hand.  (I believe I used 
http://pkl.net/~node/alsa-patch-bay.html, available from Planet CCRMA as 
an RPM).

It seems like you have everything set up (not knowing what the device 
numbers are for 63:0, 73:0, etc.).  If you have pd or vkeybd installed, 
you might want to try those for connecting to csound.  (vkeybd is in 
planet-ccrma and looks to be in debian stable).

I'll also give setting up virmidi a try, though it may be a couple of 
days until I can get some feedback here as I've just purchased a new 
laptop and am still working to get csound5 compiled on the new machine, 
as well as will be flying across the country.

I found the amidi command and used it to send simple MIDI commands to
csound5.  As a result I found (and fixed) a rather trivial error which
meant that the first MIDI event was repeated whenever there was a new
event, substituting for it.  No strong testing yet, but updated on CVS
and the Linux and source snapshot files.  Needs others to check it.
