I know, I keep forgetting about it. If it had been called 'current status', then it would make more sense...This link has a good algorithm for running status: http://www.borg.com/~jglatt/tech/midispec/run.htm Martin

HI Martin, haven't talked to you for a while .. Yes I will eventually do this. Just that I have a number of different devices with different code ie. midi to pwm, midi to stepper, emg to midi , accelerometer to midi etc. etc. . Eventually I'll crack open all the boxes and reprogram the chips. I guess I didn't pay close enough attention to the midi spec :-( I was just surprised when they stopped working. For now I'll just send a note-on between transmissions as suggested by Cyrille. Bandwidth isn't a big issue on my next project. Jim
But Jim, can't you change your receiver to handle running status? It''s
part
of the MIDI spec after all... You just need a variable to hold the last status byte received. When you
get
a data byte with no preceding status byte, use the running status. Martin

Thanks Miller,
I'd love to blame this on MSW but it works on version 0.34 in Windows
but
not 0.37 in Linux. I guess I should try 0.37 in Windows to see if the
code
has changed there as well. jim ----- Original Message ----- From: "Miller Puckette" mpuckett@man104-1.ucsd.edu To: pd-list@iem.at Sent: Monday, June 21, 2004 10:21 PM Subject: Re: [PD] Was there a change in how MIDI is transmitted ????
Here's a conjecture... maybe the MIDI driver (or the OS) has suddenly decided to start filtering the extra bytes out. That would be bad, but not the first bad thing I've seen a MSW driver and/or OS do...

I've built a few devices that accept MIDI as a control signal and they don't work with the latest version of PD. I'm not sure but it looks to me like where a ctlout object used to send Channel , Controller Number and Control Value it is only sending channel information if there is a channel change.
Not here: ctlin is sending out all three numbers at every change of a controller value. Maybe there is something wrong with your patch, like hot and cold inlets messed up?
Could you create a test patch that shows the behaviour you get?
