Sounds very similar to my problem. I also think it's a buffer problem cause when I leave everything on overnight (unused), it still works perfectly fine in the morning. The problems occur after usage. I'll check out the tip from Raphael.
Thanks!

I had the same problem with Windows XP and a RME Hammerfall DSP card using only the normal [notein], [ctlin], [toutchin] and [pgmin] for a sampling synth. I don't think it's the midi interface. RME has some of the best drivers - very stable.
Sometimes after a certain amount of time it started playing notes by itself and didn't seem to stop anymore. It sounded like notes or melodies that I had been playing before. Nothing random.
Could it be possible that midi data is written into a buffer that does not get emptied anymore? Then something might trigger reading out that buffer?
I couldn't recreate why it happened. Most of the time it didn't do it but every once in a while it did.
I had no problem ever running Nuendo for days on that same machine programming midi. The same Pd patch was doing fine on a Linux computer after switching to Linux.

I haven't seen this problem, but I have to admit I don't think I ever ran MIDI into a Windows machine for more than 2 hours at a time (back when I acually used MIDI Windows itself wasn't stable enough to run for that long at a time :)
It's hard to know whether this is the MOTU driver misbehaving in windows
7
or somethig with Pd itself - my only suggestion would be to try either (1) switching interfaces to something more modern than 828MKII or (2) try using some other software to see if the problem is specific to PD.

Dear list,
I have problems with Midi input in PD. I use Windows 7 and make use of a Motu 828MKII soundcard. I receive MIDI via a polytouchin object (make use of FSRs and a
coridium
armmite to translate pressure on the FSRs to Midi messages). All goes fine in the beginning, but sometimes after a while (f.e. 2
hours)
my Midi input starts to be random (FSRs trigger that are not supposed
to
be
triggering). If I restart PD everything is back to normal. Any idea
what
the cause of this problem might be? It's an installation project so it is difficult to restart everything
from
time to time.
Thanks in advance for your help!
