[PD] Was there a change in how MIDI is transmitted ????

[jim ruxton]

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
